OpenFaaS Gateway Documentation

repository·master·Indexed Apr 15, 2026

https://github.com/openfaas/faas

The OpenFaaS Gateway is the central entry point for serverless functions, providing a REST API, a built-in UI for deployment, and integration with Prometheus for metrics. It manages function lifecycle, handles request routing, and supports tracing via unique call IDs. The gateway acts as a proxy between clients and upstream providers like Kubernetes, Swarm, or Nomad. Key features include auto-scaling from zero, custom alerting via AlertManager, and a UI for invoking functions or deploying from the Function Store. The repository includes API specifications, provider status guides, and community resources for production use cases.
