Our verdict

Last verified Aug 25, 2026

Free, real and actively developed (v1.5.0 July 2026, 236 commits on GitHub) with perfect pricing transparency and a clear bar-manager focus, but no direct integrations and no independent review footprint yet (reputation scored from the public GitHub activity of a very young project).
