Hi HN! I'm the author of IMPulse.

About two years ago I ran into several issues with Grafana OnCall in practice:

- alert flapping caused numerous unnecessary incidents to be created

- the architecture (5 components) felt unnecessarily complex

- managing large routing trees via the UI was difficult

So I decided to build IMPulse to be IaC-ready, with Alertmanager-like routing and a single-component architecture to simplify operations for DevOps teams.

The first working version took about 3 months and already solved the problems we had internally. Later another contributor joined the project, and now IMPulse is a standalone project and we're continuing to improve it.
