Bugsink is an error tracking service that collects exceptions from running applications and presents them centrally so developers can investigate failures in production. The product is available as a hosted service or for self-hosting, using the same product and SDKs in either setup. Bugsink was created by Klaas, its solo founder and developer, after he found self-hosting an existing error-tracking platform unnecessarily difficult. Bugsink B.V. is based in the Netherlands, and its hosted service runs in the European Union.
