Side by side

What it does

A single sign-on and two-factor portal that sits in front of web apps through a reverse proxy, and also acts as an OpenID Connect provider.

A gym and body-weight tracker for planning routines, logging workouts and seeing which muscles were trained, with imports from Strong, Hevy and FitNotes.

Watch out

No admin UI for users; they live in a file or LDAP, which suits homelabs and small teams better than large organisations.

Only a few months old despite its star count, and AGPL licensed.
