GlitchTip vs Bugsink
GlitchTip and Bugsink occupy the same niche: small, self-hostable error trackers that speak Sentry's SDK protocol, for teams that want Sentry's SDKs without Sentry's platform. People weighing one are usually weighing the other, so this page compares them directly on license, hosting footprint, hosted pricing, and scope, each claim sourced to the vendor's own site or repository and dated.
Sentry SDK compatibility
Have
accepts events from existing Sentry SDKs; switching is a DSN change
Have
point your existing Sentry SDKs at it by updating the DSN, per its own site
Open-source license
Have
MIT-licensed
Partial
source-available under PolyForm Shield 1.0.0, which is not an OSI-approved open-source license; its own comparison pages say so plainly
Self-hosting footprint
Have
self-host for free with Docker; runs with a Postgres database and workers
Have
one container, no Redis, no queue, no frontend/backend split; SQLite works out of the box, per its own site
Hosted free tier
Have
a free hosted tier with a monthly event allowance
Have
hosted plans start free at 15,000 events a month
Tracing, performance, and session replay
Not published
not confirmed either way on the pages we fetched
Don’t have
deliberately unsupported by its own account: traces, performance monitoring, and session replay are not available
Uptime monitoring built in
Have
GlitchTip ships basic uptime monitoring
Don’t have
error tracking only, by design
Where RealUptime Errors fits
GlitchTip and Bugsink are both credible, currently shipping error trackers, and this page does not pick between them: if OSI open source matters, that favors GlitchTip; if the smallest possible self-hosting footprint matters, that favors Bugsink. RealUptime Errors sits beside both as the hosted, no-servers option: it is not Sentry-SDK compatible (it ships its own SDKs for JavaScript, Go, PHP, Python, and Ruby), it is scoped to error tracking exactly as narrowly as these two, and its free tier is 10,000 events a month with uptime monitoring and status pages in the same account. Whether that or either product above fits better is a decision this page leaves with you.
