I built ProTimer as a time tracker for contract developers using Claude Code. Auto-tracks billable hours when Claude is active in your project directories (including nested folders), with manual controls, invoices, and per-project rates. Everything stays local.

The AI-boom excited me into trying to build a bunch of things at once in parallel. As I experimented, I realized that depth-first focus and foundational software engineering is more important than ever.

Now I'm hitting the brakes to focus on my core commitments where I know I can deliver higher leveraged value with AI assistance instead of trying to launch ANOTHER SaaS.

So ProTimer is fully open source. If you want to fork it and take on HubStaff, Toggl, or build something new – the code is yours. MIT licensed, ready to commercialize.

Some ideas for forks: - Org & team cloud integration - Screen recording for demos

Tech stack: Tauri, Rust, TypeScript, SQLite. Works on macOS (could be ported to other platforms).

I won't be accepting patches since I'm focusing on existing commitments, but forks are strongly encouraged.
