Pros of Sentry (imho)

  - free open source
  - teams management can be delegated
  - works fine with mac, linux & windows browsers
  - maintenance free self hosted on k8s for 2 years
  - lack of mobile apps has not been issue
  - UX is ok, no complaints
  - requires little end-user support

This is the same list as the Pros for passbolt. And both ’just work’ without much maintenance or support, running self hosted on k8s for free.
