OpenFaaS

OpenFaaS turns any code into a managed serverless function on Kubernetes with a focus on portability and developer experience.

OpenFaaS simplifies the deployment of event-driven functions by abstracting the complexities of Kubernetes behind a clean REST API and CLI. It supports any language through OCI-compliant containers: simply write a handler, define your dependencies, and use 'faas-cli up' to deploy. The ecosystem provides built-in auto-scaling (from zero to many), a dedicated UI for management, and native integration with Prometheus for monitoring. By utilizing standard industry tools like Helm and the Kubernetes Custom Resource Definition (CRD), OpenFaaS avoids proprietary lock-in while maintaining the agility of a serverless workflow.
