Bugsink

Bugsink helps developers detect, understand, and resolve application errors by providing stacktraces, local variable inspection, issue grouping, alerting, and tag-based search.

It is a drop-in alternative to Sentry, teams can point existing Sentry SDKs at Bugsink by changing a single DSN setting. The platform supports all major languages and frameworks.

Self-hosting is free and runs on modest hardware; the managed hosted plan stores data in the EU and is priced predictably by event volume rather than per-seat.

Bugsink is built and operated by a solo Dutch founder under Bugsink B.V., headquartered in Utrecht, the Netherlands.
