Self-hosted alternatives to Sentry
Event-volume pricing means a bad deploy costs you twice — once in downtime, once on the invoice.
Below are 2 open-source projects that cover the same ground, each scored 0–100 on how actively it is actually maintained — commit volume, release cadence and recent trend. 1 of the 2 are currently rated healthy or better. Ordering reflects that score, not sponsorship.

How these were picked
Every project listed here is open source and can run entirely on hardware you control. We start from the categories that match Sentry's job — then rank by health score so that a popular-but-abandoned project never appears above a smaller one that is actively shipping. The scoring method is documented in full.
The scores are recomputed from repository data on every rebuild, so this page reflects the state of these projects as of 1 Oct 2026 — not the day it was written.
Bugsink
Real-time error tracking for your applications with all the details in one place. Easy setup with clear instructions included.
Best fit: Teams looking for an alternative to managed SaaS error tracking who want to keep their application logs on their own infrastructure.
Worth knowing: It uses a proprietary licence, meaning you cannot freely modify or redistribute the source code despite being able to self-host it.
GlitchTip
Error tracking app to collect errors reported by your app.
Best fit: It suits administrators looking for an open-source, self-hosted error collection tool under an MIT licence who prefer Python-based stacks.
Worth knowing: The repository shows minimal recent release activity and low engagement metrics, which may indicate a lack of active community maintenance or unpredictable upgrade paths.
