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.
