Overview
Bugsink is a young, deliberately small error tracker. Point any Sentry SDK at it by changing the DSN and it collects exceptions with stack traces, surrounding source code and local variables, groups repeats into issues even when messages contain changing IDs, and lets you search, see trends, resolve or mute issues. Source maps are supported for minified JavaScript.
It is designed to be self-hosted: a single Docker container is enough to evaluate it, it runs on ARM, and there is no per-event billing when you host it yourself, which makes millions of events cheap. Over 1,400 teams use it weekly according to its site.
A hosted service run in the EU is available for teams that do not want to operate it, starting free for evaluation and at $16 a month for 75K events with unlimited users. It does only errors: no tracing, logs, replays or uptime checks.
