As a designer who freelances on the side, I kept hitting the same two annoyances with time trackers:

- The good ones are proprietary, cloud-only, and charge
**per seat** the moment you grow.
- There's always an awkward gap between
*"hours tracked"* and *"invoice the client actually pays."* You track in one tool, then re-type everything into an invoice somewhere else.

So I built [Logr](https://logr.work) — a free, open-source, self-hostable time tracker where the timer, per-client rates, and invoicing all live on **one screen**.

##
What it does

- ⏱️ One-click timer with an automatic, live day timeline
- 💸
**Built-in invoicing** — turn unbilled sessions into an invoice in a couple of clicks
- 🔗 Shareable invoice & report links (your client just opens a URL — no account)
- 👥 Per-client / per-project billing rates
- 📥 Import your history from Toggl (CSV)
- 🤖 A built-in
**MCP server endpoint** — so you can query your own time data from an AI assistant

##
Why open-source + self-hostable

Your time entries and client data are sensitive. With Logr they live in **your own Supabase database** — not on a vendor's servers. The whole codebase is **AGPL-3.0**, so you can audit it, fork it, or host it yourself. No per-seat pricing, no feature gating, no lock-in.

##
The stack

-
**Next.js 16** (App Router) + **React 19**
-
**Supabase** (Postgres + auth + RLS)
-
**Tailwind v4** + shadcn/ui
- Deploys to
**Vercel** (one click), **Docker**, Fly.io, or any Node host

Self-host it in ~5 minutes
