What is Lyftr?

A workout tracker you fully own. Log workouts, build reusable programs, run a guided gym session with a rest timer, and track nutrition and bodyweight, all self-hosted and lightweight, with your data in a single SQLite file on your server.

No subscription. No lock-in. No "your export is a Pro feature."

Features

🏋️ Workouts	800+ exercise library, program builder, guided active mode
📱 Gym Mode	Full-screen, one exercise at a time, with a rest timer
📈 Progress	Personal records, progression charts, muscle diagrams, dashboard
🍎 Nutrition	Calories, macros, barcode scan, food search
⚖️ Weight	Trend graph, lbs / kg across all data
🔒 Yours	Self-hosted, a single SQLite file, all data on your server

Quick start

No clone, no build, just Docker:

curl -o docker-compose.yml https://raw.githubusercontent.com/Cawlumm/lyftr/main/docker-compose.yml
curl -o .env https://raw.githubusercontent.com/Cawlumm/lyftr/main/.env.example
# set a strong JWT_SECRET in .env, then pull the prebuilt images and start:
docker compose pull && docker compose up -d

Open http://localhost and create your account.

📖 Full guide: configuration, HTTPS, backups, the mobile app, and troubleshooting live in the docs → lyftr-app.pages.dev.

Try it

• Live demo: lyftr-demo.fly.dev · [email protected] / password123 (resets hourly; that account is demo-only, your own install has no default login)
• Android: download the APK from the newest release, then point it at your server (mobile docs). iOS is planned.

Translations

Help translate Lyftr into your language. See CONTRIBUTING.md for how.

Contributing

Bug reports, feature requests, translations, and PRs are welcome. Open an issue before large changes. Start with CONTRIBUTING.md for setup and conventions, and docs/TESTING.md for how the test suite is organised.

Beta: actively built, expect rough edges and frequent updates. The software equivalent of going to the gym for the first time.

Support

Lyftr is free and open source under the MIT license. Run it on your own hardware, no subscription.

The most useful things you can do are free: file a reproducible bug report, fix a doc page that was wrong, or tell another self-hoster it exists.

If you'd rather help with the running costs, sponsorship covers the demo server (~$4/month) and the developer accounts Lyftr needs to reach more platforms. The iOS app is blocked on a $99/year Apple Developer account, not on the code.
