Updated May 2026
What you gain
- ✓Self-host error tracking with no per-event or per-seat pricing as volume grows
- ✓Keep stack traces and user data inside your own network for privacy
- ✓Full access to raw error data and your own retention rules
- ✓No vendor lock-in on how errors and releases are tracked
What you give up
- △No Bugsnag-managed ingestion that scales without you thinking about it
- △No Bugsnag stability-score and release-health dashboards out of the box
- △You run the error backend, storage, and upgrades yourself
- △Fewer prebuilt mobile SDK integrations tuned by Bugsnag
Switching Cost
Bugsnag's data is portable, but its release-health and stability-score views are not, so expect to rebuild dashboards in Sentry. For most teams Sentry is the like-for-like move and can self-host, though it is heavier than Bugsnag to operate. A small team can stand up Sentry in a day or two; the deeper cost is keeping the ingestion pipeline healthy under load. The hidden cost is the on-call team learning a new error UI while production keeps throwing exceptions.

Drop-in Replacements
Ranked by feature coverage
Sentry
7185% coverageDeveloper-first error tracking and performance monitoring
Sentry catches errors in production and tells you the user who hit it, the browser they used, and the sequence of events leading up to it. Sentry catches errors in real-time and gives you everything you need to fix them.
Highlight
7765% coverageFull-stack monitoring: error monitoring, session replay, logging
Highlight captures errors, session replays, and logs together so you see the full picture when something goes wrong in production. Basically Sentry plus LogRocket combined, but open source.
Sentry is the closest self-hosted replacement for Bugsnag, and Highlight adds session replay on top. SigNoz, Uptrace, and PostHog cover errors as part of a bigger observability or analytics story. What you can't self-host away is the managed scaling Bugsnag handles for you. If you have someone to run it, Sentry is the answer. If you want it handled, that's what Bugsnag charges for.

Building Blocks
Bugsnag is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
