OpenFaaS (Functions as a Service) is a framework for building serverless functions with Docker which has first class support for metrics. Any process can be packaged as a function enabling you to consume a range of web events without repetitive boiler-plate coding.

  • Portable - runs on existing hardware or public/private cloud - Kubernetes and Docker Swarm native
  • CLI available with YAML format for templating and defining functions and featuring easy install via curl and brew
  • Auto-scales as demand increases
  • New: Kubernetes support via FaaS-netes plugin
  • New: Windows function support
  • New: Asynchronous/long-running OpenFaaS functions via NATS Streaming - Follow this guide


OpenFaaS is an independent project created by Alex Ellis which is now being built and shaped by a growing community of contributors. Project website: openfaas.com.
