GlitchTip

GlitchTip is a simple, open source error tracking application. It collects errors from a project in real time, organises them and sends alerts when and where needed.

It is compatible with the Sentry client SDKs, so existing instrumentation can be reused, but is designed to be easier to run. Besides error tracking, it monitors performance and checks site uptime in one place. It can be run on an organisation’s own server or used as a hosted service.

GlitchTip is free and open source under the MIT licence. The hosted service has a free tier and paid subscriptions.
