What is TimeTracker?

It is the web UI and API for everything from solo freelance retainers to multi-team shops: timers, Kanban, expenses, mileage, and client-ready invoices under your domain. When GDPR, SOC questions, or client contracts say “no external time SaaS,” you still get a modern product experience. Try the live demo →

Common questions

Short answers from our FAQ—see the full FAQ for detail.

Is TimeTracker really free and open source?

Yes! TimeTracker is completely free and open source, released under the GPL-3.0 license. You can use it, modify it, and distribute it without any cost. There are no hidden fees, subscriptions, or premium features locked behind a paywall.

Do I need technical knowledge to set up TimeTracker?

Basic technical knowledge helps, but TimeTracker is designed to be easy to deploy. If you're comfortable with Docker, you can have it running in minutes. We provide comprehensive documentation and step-by-step guides to help you get started, even if you're not a developer.

What are the system requirements for self-hosting?

TimeTracker has minimal requirements. You need a server with Docker support, at least 512MB RAM, and a few GB of storage. It works on Linux, Windows (with WSL), and macOS. The application uses SQLite by default, but you can also use PostgreSQL for larger deployments.

Can I use TimeTracker for multiple clients or projects?

Absolutely! TimeTracker supports unlimited projects, tasks, and clients. You can organize your work by client, project, or task, track time for each separately, and generate invoices for specific clients or projects. Perfect for freelancers and agencies managing multiple clients.

How does the invoicing feature work?

TimeTracker's invoicing feature lets you generate professional invoices directly from your tracked time. You can select specific time entries, add expenses, set hourly rates, and export invoices as PDF. The system tracks invoice status (draft, sent, paid) and supports multiple currencies.

Self-Hosted by Teams Worldwide

Teams adopt TimeTracker when SaaS renewals, data residency clauses, or per-seat math stop making sense—and they still want timers, reports, and invoices in one place.
