Overview

Bugsink is a self-hosted error tracking tool created by Klaas van Schelven, a solo Dutch developer, after he found self-hosting Sentry too resource-intensive for a client project.

It is fully compatible with Sentry's open-source SDKs, so teams can switch to Bugsink by changing only their DSN endpoint, with no application code changes required.

Key Features

Bugsink focuses narrowly on crash reporting: automatic error and exception capture, full stack traces, issue grouping, and a triage dashboard. It runs efficiently on minimal hardware, handling millions of events per month on a small VPS without requiring Redis or a separate message queue.

Pricing

Self-hosting Bugsink is always free under its Polyform Shield source-available license. For teams that don't want to self-host, a managed EU-hosted plan offers a free tier (15,000 events/month) and paid tiers starting at €16/month for 75,000 events, scaling with volume at a fraction of Sentry's per-event pricing.

Key Features

Pros & Cons

Pros

  • Dramatically cheaper than Sentry at high event volumes
  • Simple to self-host on a small VPS with minimal infrastructure
  • Drop-in Sentry SDK compatibility with no code changes
  • EU data residency available on the hosted plan

Cons

  • Source-available Polyform Shield license, not OSI-approved open source
  • Narrower feature set than full Sentry (no APM, no session replay)
  • Small, solo-founder-led company, which carries support and roadmap risk
  • Hosted plan is newer and less proven at massive enterprise scale than incumbents
