openGym
openGym is a local-AI tool - Self-hosted gym & body-weight tracker — plan routines, log workouts (supersets, warm-ups, cardio), see which muscles are trained, fatigued or detrained, import from FitNotes/Strong/Hevy, passkey login. Your data, your server.
Overview
A self-hosted gym and body-weight tracker you actually own.
Plan your week, run guided workouts, log every set and your body weight, on your phone, synced across your devices, behind your own passkey login.
Most workout apps keep your data on their servers, push you towards a subscription, or vanish when the company does. openGym runs on your own box, keeps your data in a folder you control, and is yours to fork. It still behaves like a modern app: installable on the home screen, passkey sign-in, works offline, syncs between your phone and your laptop.
No account on someone else's server, no subscription, no ads, no telemetry. One 'docker compose up' and it's running.
The in-browser demo is the real app with example data, if you want to try it before installing anything.
openGym is open-source, written primarily in JavaScript, with 13,560 GitHub stars under the AGPL-3.0 license. The latest release is v1.4.1 (2026-10-10).
