Sentry alternatives compared
Bugsink edges GlitchTip 93 to 32, and most of the difference is commit activity: 191 commits in 90 days against 3 commits in 90 days. Bugsink also has the largest following, at 2.2k stars.
The most recent release is Bugsink 2.6.2, published 8 days ago. GlitchTip publishes no tagged releases, which costs up to 25 of the 100 points. GlitchTip scores under 40, so check recent activity before adopting it. By stack, Python (2) is the most common. GlitchTip is permissively licensed. Bugsink and Telebugs are source-available rather than open source, which limits commercial reuse. Telebugs is not hosted on a forge Repoly can read, so it has no measured score yet.
