In simple English
When your server breaks in the middle of the night, someone needs an alert on their phone. This tool collects those warnings from monitoring systems and wakes the right person up. If they do not answer, it calls the next person on the list. It also uses artificial intelligence to write a summary of what went wrong. You run it on your own server for free instead of paying a monthly fee.
What it is
An open-source on-call management and incident response platform written in Go (a compiled programming language designed by Google for fast servers). It serves as a self-hosted alternative to PagerDuty and incident.io.
What it is good for
Solo developers and small teams who want professional on-call schedules, alert routing, and incident summaries without paying expensive per-user monthly subscription fees.
- No per-user licensing costs, unlike commercial alternatives.
- Supports bringing your own artificial intelligence keys for incident summaries.
- Includes one-click migration from PagerDuty and Grafana OnCall.
- Requires Docker and a server to host and maintain yourself.
- Uses AGPLv3 (GNU Affero General Public License v3, which requires you to open source your changes if you offer the software as a network service).
- Setting up chat integrations like Slack requires public network tunnels or webhooks.
