Bug reports, feature requests, 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.
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.
