onotify: A scalable, flexible Alertmanager
summary
onotify is a serverless replacement for Alertmanager built on Cloudflare Workers using durable objects, designed to be backwards compatible with Alertmanager HTTP API and config while adding built-in authentication via Cloudflare Access, paginated endpoints, and alert histories stored indefinitely. A routing tree is restructured into a DAG to memoize regex evaluations, dropping evaluation time from about ten seconds to around 300 milliseconds. The demo sends, acknowledges, and shows full alert history successfully, and webhooks sync acknowledgements with downstream sinks.
