Kimai
Kimai is open-source time-tracking software built by Austrian developer Kevin Papst in Vienna. Self-hosting is free with unlimited users, and the optional Kimai Cloud plan is hosted in Germany.
Quick facts
Self-hosting is completely free with no cap on users, and the hosted and self-hosted editions run the exact same open-source code.
It's run by a single developer rather than a company, which is worth weighing as a support and continuity risk even with the open-source safety net.
Why does it score 100?
Run from Vienna, Austria – a full EU member state.
Operated solo by developer Kevin Papst, with no outside investors or holding company.
Kimai Cloud is explicitly hosted in Germany, and self-hosting lets you choose your own server entirely.
Fully open source under AGPL-3.0 and GDPR compliant, so the whole codebase behind both editions is auditable.
