Sentry-compatible error tracking with self-hosted and managed options
NetherlandsEUEU hostedFree plan Ownership reviewed, controller unresolvedScope verdict
Bugsink B.V. identifies itself at Peter Schathof 41, 3533 HZ Utrecht, Netherlands, with KvK number 93064993. Its current self-hosted terms specify Dutch law and courts; the hosted DPA also uses Dutch law. Klaas is described as the solo founder and developer. No official shareholder or control-rights evidence was obtained, so ultimate control remains unresolved.
Bugsink B.V. in the Netherlands develops an error tracker compatible with Sentry SDKs. It groups errors into issues, displays stack traces and source context, and supports chat, email and webhook alerts.
Self-hosting and a managed service are available. The public source uses PolyForm Shield, which restricts competing products; some directories have separate licences. The hosted DPA commits personal data to EU storage and processing.
Self-hosting is advertised free, subject to the licence. Hosted Free includes 15,000 monthly events, one user and 5,000 retained events. Paid monthly plans start at EUR 16 for 75,000 events and unlimited users; 600,000 events cost EUR 50 and 3 million cost EUR 158. Premium support is EUR 15 per user/month.
