Koppl
Privacy-first time tracking you can self-host on a Pi
Most time-tracking tools lock your team's data in someone else's cloud. Koppl doesn't. Staff clock in/out from their phone with GPS, track breaks and shifts, and request leave. Managers get monthly summaries, CSV export, and built-in EU labour-law compliance (DE/CH/AT/NL) with auto-checkout. You choose where it runs: a subscription in German data centres, or fully self-hosted on your own hardware — even a Raspberry Pi. Privacy by design, GDPR-compliant, your data stays yours.
Hey Product Hunt 👋
I built Koppl because every time-tracking tool I looked at wanted to put my team's attendance data in someone else's cloud, usually outside the EU. For a lot of businesses — especially here in Germany — that's a non-starter: GDPR, labour-law rules, and simply not wanting to hand that data to a server you don't control.
So Koppl runs two ways: a managed subscription in German data centres, or fully on-premise on your own hardware — small enough to run on a Raspberry Pi. Same app either way: staff clock in/out from their phone with GPS, track breaks and shifts, request leave; managers get monthly summaries, CSV export, and automatic labour-law compliance (DE/CH/AT/NL) with auto-checkout so nobody forgets to clock out.
It's a solo build — API, web app and mobile app — with a live demo you can poke at without signing up.
I'd love feedback, especially from anyone who's fought the "where does our data actually live" battle: what would make you trust a self-hosted tool over a big cloud SaaS?
Thanks for taking a look 🙏
