Can I code Toggl?

A start/stop timer tagged to a project, saved as a row in a table, is about as simple as this register gets. The reporting on top is a handful of grouped queries. This is a genuinely easy evening.

Why CanICodeThis says Build it

  • A timer is a start timestamp and a stop timestamp — the whole feature in one sentence
  • Tagging time entries to clients and projects is a foreign key
  • Weekly/monthly summaries grouped by project are a standard aggregation query

What you give up building Toggl yourself

  • Their browser extension and idle-detection features add real polish beyond the raw timer
  • Team-wide reporting and billable-rate calculations across a company are more than solo use needs
  • Integrations with a dozen other tools (auto-start a timer from your calendar) are per-integration work

How to build your own Toggl

Genuinely one of the simplest builds on this whole register: 1. A timer is a start timestamp and a stop timestamp — the whole feature in one sentence. 2. Tagging time entries to clients and projects — a foreign key. 3. Weekly/monthly summaries grouped by project — a standard aggregation query. That's a real, complete time tracker. Out of scope: browser-extension and idle-detection features, real polish beyond the raw timer, and team-wide reporting with billable-rate calculations across a company, more than solo use needs.

What it actually costs to build

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.

AI agent — with a subscription (Claude Pro/Max, Cursor, etc.)$0 marginal
AI agent — pay-per-use API, no subscription$16–$27 one-time
Hosting, once it's running$0/mo (free tier)
Domain name, if you want your own~$12/yr

Toggl costs $9/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 3 months.
