I just finished Sparrow, an open-source (MIT) webhook delivery platform built with Go. You send it events, and it fans them out to your customers’ endpoints with retries, signing and full delivery history. It’s a self-hosted alternative to Svix, Hookdeck and Convoy.</p> <p><strong>Go bits:</strong><br> • One binary with the dashboard embedded. Postgres is the only dependency: River runs the job queue in the same database, so there’s no Redis or broker<br> • The OpenAPI 3.1 spec is generated from the Go handlers with huma on chi, and served at /docs<br> • Per-subscription Go templates reshape payloads for each receiver (Slack, Discord, PagerDuty and others ship as recipes)<br> • Standard Webhooks signing (HMAC-SHA256 and optional Ed25519), secrets envelope-encrypted at rest, SSRF checks on every outbound request<br> • OpenTelemetry traces through slog, plus Prometheus metrics<br> • A CLI with sparrow listen to receive deliveries locally, and an MCP server</p> <p><strong>Try it:</strong> curl -O <a href="https://raw.githubusercontent.com/sarathsp06/sparrow/main/deploy/docker-compose.yml" rel="noopener noreferrer">https://raw.githubusercontent.com/sarathsp06/sparrow/main/deploy/docker-compose.yml</a> &amp;&amp;
