Changelog

Every app, idea, and article added to this register, newest first. Real dates from this site's own commit history, not a rounded-off approximation — an app's date here is the day it was actually reviewed and added, not just the month. RSS feed if you'd rather follow it that way.

New appLinearIssues, statuses, and a board view are the same buildable core as every other task tracker on this register. Linear's actual differentiator isn't a feature — it's that everything feels instant, which is real, sustained interaction-engineering, not a checkbox.New appCursorAdding AI completions to your existing editor via a plugin is genuinely achievable, and this register's own GitHub Copilot entry already covers exactly that. Cursor is a different, bigger undertaking underneath: an entire maintained fork of a code editor, not a plugin layered on top of one.New appPerplexityA single search-then-summarize call is a genuinely achievable weekend integration. A continuously-fresh, web-scale index plus real-time orchestration across multiple frontier models is the entire actual product, and it's server-farm-scale infrastructure, not a bigger version of the same weekend build.

New ideaAn AI Ad Copy GeneratorGenuinely one of the simpler builds here — a prompt template layer over an existing LLM API, not a proprietary model of your own.New ideaA Customer Support Shared InboxA human-staffed shared inbox — support email that becomes an assignable, trackable conversation — is a genuinely different, simpler build than an AI chatbot, closer to a well-organized email client than a specialist support platform.New ideaA Database With Custom ViewsOne table, typed columns, a CRUD UI, and a form to add rows is standard, bounded work — multiple synchronized views over the same data, kept live as you edit any of them, is where the real depth is.New ideaAn E-Signature ToolFor genuinely low-stakes documents, a signature flow is a bounded, achievable build — upload a PDF, capture a signature, flatten it onto the page. The audit-trail and legal-recognition weight of a real e-signature product is the deeper, deliberately out-of-scope part.New ideaAn Employee Time-Off TrackerA time-off request flow — an employee submits, a manager approves, a calendar shows who's out — is genuinely one of the simpler builds on this register, well within reach for a small team.New ideaA Form BuilderA form builder with a handful of field types, storing responses, is genuinely well-bounded — one of the more approachable builds on this whole register.New ideaA Freelance Time TrackerA start/stop timer logging billable hours against a client and project is genuinely one of the simpler builds on this whole register — well-bounded CRUD with a running clock, distinct from volunteer or personal time tracking in exactly one field: a billing rate.New ideaA Kanban Task BoardCards, lists, and drag-and-drop reordering is genuinely one of the more approachable builds here — existing kanban libraries handle the fiddly reordering math, leaving a straightforward schema and CRUD API underneath.New ideaA Markdown Note-Taking AppA markdown editor with live preview and local storage is genuinely one of the simpler builds on this whole register — mature, well-documented libraries handle the editor itself, leaving mostly straightforward CRUD underneath.New ideaA Meeting Booking PageGenuinely one of the more approachable builds on this whole register — Google Calendar and Microsoft Graph both expose free/busy lookups in a single API call, and the rest is bounded slot math and one transactional email.New ideaA Podcast Hosting ToolHosting an audio file and generating an RSS feed is genuinely achievable — it's a specific, simple, well-documented XML format, not something to guess at. Automatic distribution and detailed analytics are the deeper, ongoing part.New ideaA Product Analytics DashboardLogging a custom event and building a simple funnel chart is genuinely achievable — comprehensive behavioral cohort analysis at real product scale is the deeper, ongoing part this stays clear of.New ideaA Read-It-Later AppGenuinely one of the simpler builds here — a browser extension sending a URL to your server, plus an existing readability library doing the hard part of content extraction.New ideaA Simple Bookkeeping LedgerA personal or small-business ledger you use for your own tracking (not tax filing) is a genuinely implementable double-entry data model, the same core pattern behind this register's own QuickBooks and Xero entries.New ideaA Simple Online StoreA product catalog with Stripe Checkout is genuinely one of the more approachable builds here — the same core pattern behind every e-commerce entry in the register, scoped down to what a small storefront actually needs.New ideaA Social Media Post SchedulerA queue, a composer, and a scheduled worker that posts at the right time is genuinely a real day's work for one or two platforms with open APIs — the whole product collapses into a script at that scale.New ideaA Workflow Automation ToolFor a couple of personal services with a linear trigger-and-action, this is genuinely one of the simpler builds here — direct API calls in a small script, not a general routing platform.New ideaA Writing Proofreading AssistantA hotkey-triggered proofreader wrapping an existing LLM API covers most real usage — real-time inline underlining across every app, the way Grammarly works, is the deeper, deliberately out-of-scope part.New article5 Things You Should Never Vibe Code (And Why)Five categories where this register's answer is always the same, not because it's hard, but because of who bears the risk when it's wrong. Real examples.New articleThe 90/10 Rule for Build vs. Buy: We Checked the DataThe 90/10 rule says buy 90% of your software, build 10%. We checked it against 200+ real apps with real buildability scores. The real split isn't 90/10.New articleHow to Write a Build Prompt an AI Agent Can UseThe difference between a vague prompt and a usable one, shown with a real before-and-after from this register's own history, not a made-up example.New articleThe Real Cost of Maintaining What You Vibe Code85% of buildable apps in this register cost $0/mo to host. The real ongoing cost isn't hosting bills — it's the maintenance no calculator prices.

New appWispr FlowA hotkey that records your voice, sends it to a speech-to-text API, and pastes the result into whatever field you were typing in is a genuine weekend build. What you won't match in a weekend is the latency, and latency is the entire experience.New articleHow Much Does It Cost to Build a SaaS With AI?Real numbers from 173 reviewed apps: what an AI agent build actually costs in agent usage and hosting, not a guess.New articleMVP Scope: What to Build First (and What to Cut)The single most common reason a vibe-coded weekend project fails isn't the code — it's scope. Every idea on this register splits its build into an MVP and a v2 for exactly this reason.New articleSaaS Apps With Real Moats: 5 Reasons to Just PayEvery JUST PAY verdict on this register has a specific, different reason — not just 'it's hard.' Five real categories of moat, with real examples.New articleAI Coding Agents: Subscription vs. Pay-Per-UseThe two ways to pay for an AI coding agent lead to genuinely different decisions about what's worth building. Here's the actual tradeoff, not a tool recommendation.New articleThe Vibe Coding Stack: What to Actually UseThe same handful of tools show up in almost every build prompt on this register. Here's what they are and why, including where this site itself draws the line at 'just use this instead.'

2026-08-17

New appBannerbearGenerating a branded image from a template by swapping in text and data is well-documented compositing work — genuinely achievable, closer to this register's QR-code and background-removal simplicity than a design tool's rendering-engine complexity.New appDeepLSending text to an existing translation API and returning the result is a thin, honest wrapper — you're integrating an existing translation model, not building one.New appObsidianThe core app itself is free — local markdown files with backlinks parsed between them is genuinely achievable, well-documented work. The paid tier is really just their optional sync and publish add-ons, not the note-taking itself.New appSenjaA form collecting a quote or short video, and a widget displaying them, is genuinely simple CRUD plus a file upload — one of the more approachable builds in the whole register.New appZeroBounceChecking whether an email address is likely valid is a well-documented pattern combining format checks and a mail-server handshake — genuinely one of the more approachable builds on this register.New appApifyFor your own small-scale scraping needs, a headless-browser script genuinely works well and costs nothing — the same 'self-hosted covers personal scale' pattern as this register's Algolia entry. Reliable scraping across thousands of hostile, anti-bot-protected sites at scale is the real infrastructure.New appClerkyFilling a standard incorporation document template shares this register's DocuSign-style build pattern. Cap table math and legal correctness for equity issuance carry real financial and legal weight that basic templating doesn't cover.New appElevenLabsShares this register's text-to-speech idea's exact shape: calling an existing voice-synthesis API is a thin, achievable wrapper. Cloning a specific real person's voice is a different, more sensitive capability with real consent stakes.New appGongRecording and transcribing sales calls shares this register's Otter.ai build pattern closely. Extracting genuinely useful sales-coaching insights from that transcript — not just words, but what actually predicts a deal closing — is real, separate applied analysis.New appLobCalling an existing print-and-mail API to send a physical letter or postcard is a bounded, well-documented integration. Actually running the print facilities and postal logistics behind it is real physical infrastructure, not something to replicate.New appResendRecommended constantly throughout this register's own build prompts as the email component, and worth reviewing honestly: sending one email via SMTP is trivial. Reaching real inboxes reliably at any volume is an ongoing reputation problem, not a one-time build.New appSmile.ioA points ledger and reward redemption is genuinely bounded CRUD. Integrating cleanly across many different e-commerce platforms, each with their own checkout flow, is the real, ongoing depth.New appAdobe Premiere ProShares this register's video-editing moat: a real-time, frame-accurate video editing engine handling multiple tracks, effects, and color grading is specialist rendering engineering refined over decades, not a weekend feature.New appChatGPT PlusThe honest, humble entry: a chat UI calling an LLM API is genuinely simple, this register's own ideas do it constantly. Training a competitive foundation model from scratch is a different order of magnitude entirely — genuinely not a weekend, or a year, project.New appDeelShares this register's Ramp and Bench reasoning: a payroll dashboard is buildable software. Correctly navigating employment law and tax withholding across dozens of countries is regulated compliance infrastructure, not a coding project.New appHelloFreshThe app half — browsing recipes, planning a week, generating a shopping list — is exactly what this register's own recipe-organizer idea already covers. Sourcing, portioning, and cold-chain shipping real ingredients to someone's door is physical logistics, not code.New appLinkedIn RecruiterA candidate database and outreach tracker for your own contacts is genuinely buildable, similar to this register's Apollo case. LinkedIn's real value is a professional network hundreds of millions of people already maintain — that has no code equivalent.New appRobinhoodA portfolio dashboard showing your own holdings is genuinely buildable. Being a licensed broker-dealer that executes real trades on real exchanges is heavily regulated financial infrastructure that individuals cannot legally operate without registration.New appSpliceShares Spotify's exact problem: a file browser and audio player is simple software. The catalog — millions of licensed, royalty-cleared samples from real producers — is the entire product, and that's licensing, not code.New appSplineShares Figma's canvas-rendering-engine problem, with a third dimension added — a real-time, precise 3D scene editor in the browser is genuinely harder than 2D, specialist graphics engineering most builds never approach.New appStripeReferenced in nearly every build prompt on this site as the payments component, and worth reviewing directly: PCI compliance, banking partnerships, and fraud detection at real scale are regulated financial infrastructure that individual developers cannot legally or practically replicate.New appSupabaseGenuinely nuanced: the database engine underneath (Postgres) is free, open-source, and referenced constantly in this register's own stack recommendations. What you're paying for is managed hosting, auth, and realtime layered on top — convenience, not the core technology.New appVercelThis site's own build prompts recommend Vercel or Cloudflare Pages constantly — worth being honest about why: global edge infrastructure, instant preview deployments, and automatic scaling are precisely the kind of thing you rent, not build, even for a site whose whole premise is build-it-yourself.

New ideaAn AI Quiz Generator From My NotesSending your notes to an LLM API and asking for quiz questions back is a well-crafted, achievable prompt. Getting genuinely good, non-repetitive questions across many study sessions takes real prompt-tuning care.New ideaAn AI Text-to-Speech Narration ToolSending text to an existing text-to-speech API and returning an audio file is mostly a thin, honest wrapper — you're integrating an existing voice model, not building one.New ideaA Call Recording and Transcription ToolRecording a call and running it through an existing speech-to-text API is genuinely achievable. Actually connecting to phone lines to capture the call in the first place needs real telephony infrastructure, not just transcription.New ideaA Citation and Bibliography ManagerStoring sources and formatting them into a citation style is mostly well-specified templating work — citation formats are documented standards, not a research problem.New ideaA Custom Quiz/Trivia Game AppA host screen and player screens synced over WebSockets, showing a question and tallying answers, is a genuinely achievable real-time build — the entertainment counterpart to this register's live-polling idea.New ideaA Digital Tip Jar / Donation PageA page with a Stripe payment button and a thank-you message is about as simple as accepting money online gets — genuinely one of the more approachable builds here.New ideaAn Event Ticket Sales PageA page describing an event with a Stripe Checkout button and a generated ticket is genuinely simple — one of the more approachable builds in this library.New ideaA Group Decision Polling ToolA poll with a few options and a shareable link is genuinely simple — the same shape as this register's Doodle build, just deciding on an option instead of a meeting time.New ideaA Personal Subscription TrackerA list of your own subscriptions with renewal dates and a running total is genuinely simple CRUD — fittingly, given this whole site exists to help you decide which of those subscriptions to keep.New ideaA Pet Health Record TrackerVaccination dates, vet visit notes, and weight logs for a pet are a small, well-understood data model — genuinely one of the simpler builds in this library.New ideaA Product Changelog PageA list of dated entries describing what changed is about as simple a content tool as exists on this whole register.New ideaA Raffle/Giveaway Winner PickerCollecting entries and picking a random winner is about as small a build as this library has — a form, a list, and one call to a random number generator.New ideaA Recipe Organizer and Meal-Prep PlannerSaving your own recipes and dragging them onto a weekly calendar is well-bounded CRUD with no AI generation involved — genuinely simpler than an AI meal planner, just organizing recipes you already have.New ideaA Rental Property Management ToolTracking tenants, leases, and rent payments for a handful of properties is genuinely bounded CRUD. Automated rent collection and maintenance-request routing add real, separate scope.New ideaScheduled Time-Capsule MessagesWrite a message now, deliver it by email on a future date — genuinely one of the simplest ideas in this whole library, just a form and a scheduled job.New ideaA Simple CRM for Real Estate AgentsLeads, showings, and a deal pipeline share this register's general CRM build spec closely — the buildable core is the same, just with real-estate-specific fields and a showings calendar layered on.New ideaA Split-Bill Group Expense ToolTracking who paid what and computing a simplified 'who owes whom' balance across a group is genuinely well-specified arithmetic — a real, achievable weekend build.New ideaA Study Session Pomodoro TimerA countdown timer alternating work and break intervals, with a log of completed sessions, is genuinely simple — one of the more approachable builds in this whole library.New ideaA Subscription Billing Management ToolStripe Subscriptions handles the actual recurring charge and card storage for you — the real work is your own dashboard for plans, upgrades, and what happens when a payment fails.New ideaA Team Password ManagerShares 1Password's exact reasoning: a form storing text is trivial, but encrypting it correctly enough that a breach doesn't expose every password is applied cryptography most teams should rent, not build.New ideaA Two-Factor Authentication ServiceGenerating a time-based one-time code is a well-documented, simple algorithm. Being the trusted identity layer other applications rely on to keep their users' accounts secure is a different, much higher-stakes undertaking.New ideaA Voice Memo App With TranscriptionRecording audio and sending it to an existing speech-to-text API gets you a real transcript quickly — that part is thoroughly solved. It's the same well-bounded core as Otter.ai, just aimed at quick personal notes instead of meetings.New ideaA Volunteer Hour TrackerVolunteers signing up for shifts and logging hours worked is genuinely simple CRUD — a small, well-bounded scheduling-and-logging problem for a nonprofit or community group.New ideaA Warranty and Receipt TrackerPhotographing a receipt and logging its warranty expiration date is genuinely simple CRUD with a file upload — one of the more approachable builds here.New ideaA Website Uptime MonitorA scheduled job pinging a URL and emailing you if it fails is genuinely simple — this register's UptimeRobot itself scores near the top for exactly this reason.

2026-08-15

New appCarrdA single-page site with a hero, some sections, and a contact form is about as simple as this register gets — Carrd's whole pitch is being the simplest possible page builder, which makes it a very reasonable evening build.New appCopy.aiShares Jasper's exact shape: a prompt-and-template layer over an LLM API, no proprietary model to replicate, just a clean UI for a call you can make yourself.New appCraftStructured, document-style notes with nested blocks are the same well-bounded editor pattern as Bear's — genuinely one of the more approachable builds on the register.New appFomoA small popup showing 'someone in Austin just bought this' is a tiny script and an event feed — genuinely one of the simplest builds on the whole register.New appOriginality.aiSend text to an existing AI-detection or plagiarism-checking API and show the score — a thin, honest wrapper, the same shape as this register's simplest API-integration builds.New appQR Code GeneratorGenerating a QR code is one line with a mature open-source library. The paid tier is really selling a dynamic, trackable, editable-after-printing redirect — which is just a URL shortener wearing a different hat.New appReadMeRendering API documentation from an OpenAPI spec into a browsable, testable page is well-documented, mechanical work — several open-source tools already do most of it.New appRemove.bgUpload an image, call an existing background-removal API, return the result — genuinely one of the simplest builds on the whole register, a thin, honest wrapper around someone else's model.New appTermlyFilling a legal-document template and generating a cookie-consent script is genuinely mechanical work — the templates themselves, not the code, carry whatever legal weight they have.New appActiveCampaignShares Mailchimp's buildable sending core. ActiveCampaign layers behavioral automation on top — if a subscriber does X, wait, then do Y — which is a small workflow engine, the same challenge every automation-capable tool on this register faces.New appApolloTracking outreach to your own contact list shares this register's CRM build spec. Apollo's actual differentiator is a huge, continuously-verified database of other companies' contact details — a licensed-data problem, not a build problem.New appAppcuesA tooltip pointing at a button, shown once per user, is a well-bounded UI pattern. A visual no-code builder letting a non-engineer design onboarding flows for any app is a much deeper, different product.New appBeehiivShares Substack's exact shape: writing and sending posts is genuinely buildable. Beehiiv adds real growth tooling — referral programs, ad network placement — on top, which is a second, separate product.New appBonsaiContracts, invoicing, and time tracking for freelancers are each independently buildable — the real work is stitching three genuinely different small tools into one that feels coherent.New appClickFunnelsA single landing page is Unbounce's easy case. A multi-step funnel — landing page, upsell, downsell, each tracked and connected — is a genuinely bigger, if still bounded, build.New appFrame.ioUploading a video and letting a team leave timestamped comments shares this register's video-hosting buildable core. Frame-accurate scrubbing and annotation drawing on top of the video are the fiddlier part.New appGitHub CopilotA code-completion tool wrapping an existing LLM API is genuinely achievable — this whole site is built on the same idea. Training your own competitive code-generation model from scratch is a different universe of effort entirely.New appHeadspaceA meditation timer with your own recorded sessions is a genuine weekend build. A large, professionally-produced library of guided programs with a personalization layer is closer to Spotify or Audible's licensed-content case.New appHootsuiteShares Buffer's exact pattern: a queue and a scheduled worker is genuinely buildable. The real cost is on the platforms' side — each network's posting API has its own approval hoops, not a code problem.New appMakeShares Zapier's exact profile: one trigger, one action, genuinely buildable. Make's visual flowchart-style branching adds real workflow-engine complexity beyond a linear automation.New appMicrosoft TeamsShares Slack's exact shape: channels and real-time chat are genuinely buildable. What you'd be giving up is everything living inside the Microsoft 365 ecosystem it's bundled with.New appMonarch MoneyShares YNAB's exact profile: budgeting logic is clear, well-specified arithmetic. Live bank-account sync is the one piece worth respecting rather than hand-rolling.New appOptimizelyBasic A/B testing — split traffic, track conversions, compare — is genuinely simple. Statistically rigorous results at enterprise scale, with feature-flagging and team workflows layered on, is a different, deeper product.New appScreaming FrogCrawling your own site and flagging broken links or missing meta tags is a genuinely bounded weekend build. Screaming Frog's depth — hundreds of technical SEO checks refined over years — is a different scale.New appShippoCalling a few carrier APIs to compare rates and buy a label is a bounded, well-documented integration. Doing it across dozens of carriers with reliable, up-to-date rate tables is real, ongoing maintenance.New appSlidoA live poll with results updating in real time on everyone's screen is a genuinely achievable WebSocket build. Handling thousands of simultaneous audience members reliably is where the real infrastructure care lives.New appStreamYardA multi-guest call room built on an existing WebRTC SDK is genuinely achievable. Simultaneously broadcasting that call live to YouTube and other platforms is real, separate streaming-protocol work.New appSynthesiaTurning text into a video with an AI avatar is mostly a well-crafted API call to an existing text-to-video model — a genuinely different situation from most video tools on this register, closer to Jasper's case than Loom's.New appVidyardRecording and hosting a video shares Loom's buildable core. Vidyard's real differentiator is viewer-level analytics wired into a CRM — who watched, how far, and when a sales rep should follow up.New appWhen I WorkA shift schedule with a grid of employees and time slots is genuinely bounded, well-understood CRUD. Handling shift swaps and conflict-free scheduling across many employees is where the real fiddliness starts.New appWherebyA simpler case than Zoom's: no-download, browser-based video calls built on an existing WebRTC SDK are genuinely achievable for small groups, though real-time video infrastructure at any real scale remains the hard part.New appWistiaShares Loom and Vidyard's exact pattern: hosting and playback are buildable, viewer-level analytics tied to marketing tools are the real depth.New appAdobe InDesignShares Photoshop and Illustrator's exact problem: page layout at print quality, with precise typography and color management, is specialist rendering-engine work refined over decades.New appAudibleShares Spotify's exact problem: an audio player with a library is simple software. The catalog is the entire product, and audiobook publishing rights aren't something a rebuild acquires.New appBenchThis isn't really software you're paying for — it's a human bookkeeper's monthly labor, delivered through a nice dashboard. No amount of good code replaces a person reconciling your books.New appCulture AmpSending a survey and charting the results shares this register's NPS-survey build pattern. Culture Amp's actual value is benchmarking your scores against thousands of other companies' data — that's licensed, aggregated data, not a build.New appDuolingoA flashcard app with a streak counter is a weekend project. A spaced-repetition algorithm tuned against hundreds of millions of learner interactions, across dozens of professionally-designed courses, is a different scale of product entirely.New appEtsyA single-seller storefront is genuinely buildable — this register proves it repeatedly. Etsy's real value is the marketplace network: millions of shoppers already browsing for handmade goods, which no new storefront starts with.New appHireVueRecording a candidate's video answers is buildable — this register's video build spec covers it. Automated AI analysis of interview responses to score candidates carries real bias and fairness stakes that make this a genuinely different kind of project than most on this register.New appKajabiThe course-and-paywall core shares Teachable's buildable shape. Kajabi's actual pitch is bundling that with email marketing, funnels, and a website builder — the same integration-ecosystem moat that makes HubSpot a JUST PAY, not any single hard feature.
