passkeys

Developer Duarte Santos released openGym, an open-source, self-hosted gym and body-weight tracker built in JavaScript. Users can plan routines, log workouts including supersets, warm-ups and cardio, and see which muscles are trained, fatigued or detraining. It supports importing data from FitNotes, Strong and Hevy, offers passkey login, and keeps all data on the user's own server, a privacy-focused pitch that is drawing interest from the self-hosting community.
