About this project

OpenFaaS is a framework for packaging and running event-driven functions and microservices on Kubernetes. Developers wrap code or an existing binary in an OCI-compatible/Docker image to expose a scalable endpoint with auto-scaling and metrics, avoiding repetitive boilerplate. Key capabilities described in the README: - One-click install and a UI portal for ease of use. - Write functions in any language via a Template Store or a Dockerfile; official templates include Node.js (node20), Python 3 (python3-http) and Go (golang-middleware). - Build and ship code as an OCI-compatible/Docker image. - Portability: runs on existing hardware or public/private cloud by leveraging Kubernetes (faas-netes). - A CLI with YAML format for templating and defining functions. - Auto-scaling as demand increases, including scaling to zero. - Trigger endpoints via HTTP or event sources such as Apache Kafka and AWS SQS. - Built-in queuing and background processing for async tasks. - GitOps quick-start via OpenFaaS Cloud. - Deployment to Kubernetes or OpenShift, plus faasd as a lightweight alternative. - Integration with service meshes such as Istio or Linkerd through featured tutorials. - Grafana dashboards for observing auto-scaling. Licensing and editions: this repository is part of OpenFaaS Community Edition (CE), licensed for individual exploration and hobbyist use, with a 60-day limit for commercial proofs of concept. Commercial and production workloads require OpenFaaS Standard or OpenFaaS for Enterprises, which are separate commercial products with commercial support and CVE maintenance. The README states CE has usage restrictions and more basic capabilities than the commercial versions. Project background: OpenFaaS is written in Go and was created by Alex Ellis; it is hosted by OpenFaaS Ltd and is a registered trademark in England and Wales. Third-party contributions to the source code are made under the MIT license, while contributions from OpenFaaS Ltd fall under the OpenFaaS CE EULA. The README notes that public repositories form OpenFaaS CE and that product development occurs in private repositories, so GitHub activity does not represent the full product.
