The core infrastructure backend (API, database, Docker, etc). (by bitwarden)

Project mention: Lastpass no longer accept payments for subscribers with ProtonMail domains. | /r/ProtonMail | 2023-06-05

I'd suggest moving to Bitwarden. Free and Open Source ($10/year for pro features)
KeeWeb

Project mention: 1Password alternative...? | /r/macapps | 2023-05-09

Project mention: Has anyone tried PassBolt? | /r/MykiSecurity | 2023-05-12
Padloc

8 2,271 8.6 JavaScript

A modern, open source password manager for individuals and teams.

Project mention: Bitwarden Raises $100M | news.ycombinator.com | 2022-09-06

I just looked at your CI. Very very few automated tests. It isn't a deal breaker (Bitwarden honestly isn't much better), but it doesn't instill much confidence in your application either.
