2 sourcesShow HN: Spooled – Open-source webhook queue and job runner built in Rust
Hey HN,
I built Spooled because I was tired of setting up Redis + Sidekiq/Bull every time I needed background jobs, and watching webhooks fail silently with no visibility.
Spooled is a single Rust binary that handles:
- Job queues with automatic retries and exponential backoff
- Webhook delivery with real-time status via SSE
- Dead-letter queues (failed jobs aren't lost)
- Cron scheduling
- Job dependencies / workflows
- Multi-tenant with API key auth
It's self-hosted, needs only Postgres, and deploys in one command:
docker run -p 8080:8080 ghcr.io/spooled-cloud/spooled-backend:latest
REST and gRPC APIs. SDKs for Node.js, Python, Go, and PHP.
