Toggl vs Harvest: could you build either?

A timer, a table and a report. Harvest costs more because it bolts invoicing on top — which is the one part of this rebuild that adds real work.

These two split: Toggl is the more realistic rebuild, Harvest the one to think twice about. Toggl is an evening of work against a weekend of work for Harvest. Harvest lists at $13.75/mo against $9/mo for Toggl, a difference of $57 a year.

Why Toggl gets 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

Why Harvest gets Borderline

  • The timer and project-tagging core is identical, simple work to Toggl's
  • Generating an invoice from a date range of tracked time is a query plus a PDF template
  • Basic expense line items attached to a project are ordinary CRUD

Where the builds overlap

Both rebuilds are made of parts from the Vibe Codeability Database. The shared ones are work you'd do once either way — the split ones are what actually separates these two.

What you lose leaving Toggl

  • 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

What you lose leaving Harvest

  • Their forecasting/resource-planning module (who's available for new work next month) is a separate, deeper feature
  • Approval workflows for team timesheets add a small workflow layer beyond solo tracking
  • Payment collection on the invoice (accept a card) needs a real payment integration if you want it

Questions

Is Toggl or Harvest easier to build yourself?

These two split: Toggl is the more realistic rebuild, Harvest the one to think twice about. Toggl is an evening of work against a weekend of work for Harvest. Harvest lists at $13.75/mo against $9/mo for Toggl, a difference of $57 a year.

Can I build Toggl?

Build it. 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.

Can I build Harvest?

Borderline. Timer tracking is the easy part, same as Toggl. Harvest adds invoicing straight from tracked hours and expense tracking on top, which is a genuinely reasonable weekend rather than an evening, but still well within reach.

What do Toggl and Harvest have in common technically?

Both rebuilds need landing page, crud database, user login. That shared foundation is why they score similarly on the parts they overlap on — the difference comes from what each one adds on top.
