Scratching my own itch to get alerts when a job / task / service has failed and near real-time alerts are needed. You can self host it, you can use email or webhooks for alerts.
My motto for this little project is "just tell me when it breaks". I like to think of it as an anti-observability tool, good devs know where issues are anyway, but they do need to know when stuff has gone down. Hope it helps someone, this is probably the second time I publish an OSS project since LokiJS back in 2014.
Used VSCode / GH Copilot (Sonnet 4.5) for writing tests and some refactoring.
