A European Alternative to Sentry

Error trackers help you debug production errors by providing as much information about the context as possible. That automatically means they store sensitive production data. Where that data is stored — and by whom — matters.

If you need a European alternative to Sentry, Bugsink is a Sentry-compatible error tracker. Compatible means: just swap out the DSN and you’re good. For an existing Sentry setup, that can be a one-minute change.

European means: built by a European company and, when we run it for you, hosted on European infrastructure. Or, if you prefer, Self-Hosted on your own infrastructure, so the error data never leaves your systems.

Bugsink focuses specifically on error tracking: grouped issues, stack traces with local variables, alerting, and triage information. The Error Tracking page covers each of these and many other features.

Hosted in the EU

With the hosted service, we run Bugsink for you in Europe. We provision your instance at name.bugsink.com and take care of the infrastructure, certificates, upgrades, storage, and retention. You point your applications at Bugsink; we take care of the rest.

The hosted service is supplied by Bugsink B.V. in the Netherlands. We store and process all hosted personal data in the EU, using EU-based subprocessors for application data. We make those commitments in our DPA.

Pricing

The Free plan is limited to one user and one team. Paid plans start at $16 per month and include unlimited users and teams. Higher plans also increase the number of events accepted each month.

Events/month Price/month
15K Free
75K $16
600K $50
3M $158
15M $568
50M $1,288

Bugsink is cheaper than Sentry at every paid level. For example, 600K events per month costs $50 with Bugsink, while Sentry Team costs about $132 for 500K.

At higher volumes, the difference grows even further: Bugsink is up to 5× cheaper than Sentry. At 50M events per month, that’s $6,441 for Sentry Team versus $1,288 for Bugsink.

Self-hosted

Bugsink can also be run entirely inside your own infrastructure. Self-hosting means the error data never leaves systems you operate yourself. For organizations with strict data handling rules, this can be the simplest answer.

Unlike many observability platforms, Bugsink is designed to run with minimal infrastructure. In the simplest setup it runs as a single container. If you want to evaluate Bugsink locally, you can start a temporary instance with Docker:

docker pull bugsink/bugsink:latest

docker run \
  -e SECRET_KEY=dfA7qSxmxxQFbrviftzz0JIGaAT83wpZ6cGgHQIx4QPnjfH0Qn \
  -e CREATE_SUPERUSER=admin@example.org:admin \
  -e PORT=8000 \
  -p 8000:8000 \
  bugsink/bugsink

Visit http://localhost:8000/ to log in.

Full installation instructions are available in the documentation.

Migration from Sentry

Already using Sentry? You don’t need to change your application code.

Bugsink accepts standard Sentry SDK events, which means migration can be as simple as updating the DSN.

  • Same client libraries
  • Same event format
  • Change the DSN and start sending errors elsewhere

This makes it possible to migrate incrementally or all at once.

Why this matters more now

The concern itself isn’t new. GDPR has applied since 25 May 2018, and error trackers routinely store stack traces and request context that can include personal data. Keeping that data inside the EU avoids the entire “international data transfer” discussion.

More recently, the topic has widened beyond compliance. European governments increasingly talk about digital sovereignty and cloud exit strategies — the ability to run critical infrastructure without depending on foreign-controlled services.

Recent geopolitical events reinforced that concern. In January 2026, the U.S. administration again discussed taking control of Greenland, and earlier sanctions against the International Criminal Court showed how infrastructure and jurisdiction can intersect with politics.

For developers and organizations handling production systems, the takeaway is straightforward: where software runs and who controls it matters.

Conclusion

Error trackers get to see a lot: the context they collect includes your code (stacktraces), and arbitrary data from your production systems. That is what makes them useful, and it is also why you care who runs them. Where that data goes, and who controls it, matters more than ever.

Bugsink is a European alternative to Sentry, with EU hosting and a self-hosting option. It is compatible with the Sentry SDKs, so you can migrate by simply changing the DSN. So stop reading and Sign up for free.
