About Bugsink
Bugsink captures production errors and surfaces the exact code path that failed — delivering full stacktraces with local variables and automatic issue grouping so teams can triage quickly. Designed as a drop-in Sentry replacement, it works with existing SDKs across Python, JavaScript, Ruby, PHP, Java, Go, and Rust, and is positioned to be up to 80% cheaper at scale.
The platform ships as a single Docker container that teams can self-host on their own infrastructure, or run via the managed EU-hosted service. Bugsink speaks the Sentry protocol, so no code rewrites are required — switching is a config change. Sourcemaps, release tagging, and tag-based filtering all work out of the box.
Key benefits:
- Sentry-compatible SDKs for drop-in migration without code changes
- Self-hosted Docker deployment with unlimited users on the free tier
- Automatic issue grouping that collapses duplicate errors into one
- Sourcemap support for readable stacktraces from minified JS
- Release and environment filtering to pinpoint regressions fast
- Alerting and search across issues, tags, and user context
Bugsink is built and hosted in the European Union, offering a GDPR-friendly error tracking stack with full data sovereignty. With 800+ teams using it weekly and an open development model on GitHub, it is a transparent, EU-native alternative to Sentry for teams that want control over where their crash data lives.
Why choose Bugsink over Sentry?
The decisive argument is data jurisdiction. Sentry is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes — the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Bugsink removes that overhead. As a Netherlands-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors — health, public administration, finance — that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
