OpenFaaS

OpenFaaS is an open-source platform that enables serverless functions on Kubernetes, simplifying deployment and scaling of event-driven workloads. It solves the complexity of managing infrastructure for functions, including autoscaling, queuing, and event triggers. The platform targets developers, DevOps teams, and enterprises that need to run functions on-premises or in the cloud, with support for multiple languages and existing microservices. It is positioned as a portable, production-ready alternative to managed serverless offerings, with commercial support and enterprise features available.
