Why switch
Why teams move off Sentry
Self-hosting is not only about saving money. These are the reasons people make the switch.
Own your data
Your data lives on a server you control, not on Sentry's infrastructure. No surprise policy changes and no lock-in.
No per-seat pricing
Open-source alternatives to Sentry are free to run for as many users as your server can handle. A small VPS often costs less than a single subscription.
Customize and extend
Read the code, add plugins, connect it to your own tools and automate it through open APIs. When you need a feature, you can build it or fund it.

What is the best open-source alternative to Sentry?
Sentry Self-Hosted is the most popular open-source alternative to Sentry, with 45,479 GitHub stars. Bugsink and Rustrak are also strong choices. Compare features, license and recent activity to find the best fit for your team.
Is there a free alternative to Sentry?
Yes. All 4 apps on this page are open source and free to self-host, so you can run a Sentry replacement without per-user fees. You only pay for the server, and a small VPS is usually enough for personal use or a small team.
Can I self-host an alternative to Sentry?
Yes. Bugsink, Rustrak and Langfuse ship a Docker image, so you can run them on a home server or VPS with Docker Compose in a few minutes. Your data then stays on hardware you control.
How do I migrate from Sentry?
Start by exporting your data from Sentry, then check the import options of the app you pick, since many projects ship importers for popular formats. Run both side by side for a week before you switch so nothing is lost.
