What is OpenFaaS?

OpenFaaS makes it easy to deploy event-driven functions and microservices to Kubernetes without repetitive boilerplate. Created by Alex Ellis in 2016, it has grown into a mature platform with both a free Community Edition and commercial Pro/Enterprise offerings.

Functions are packaged as OCI-compatible container images, meaning any language or binary that can run in a container works with OpenFaaS. The project provides official templates for popular languages to get started quickly, but custom Dockerfiles are fully supported.

OpenFaaS Pro adds features like scale-to-zero, Kafka and SQS event connectors, Single Sign-On, RBAC, and monitoring dashboards. Enterprise customers use it for multi-tenant function platforms, ETL pipelines, and as sandboxes for customer-provided code.
