Cloud native FaaS platform for running Serverless workloads with ease

OpenFunction is a cloud-native open source FaaS (Function as a Service) platform aiming to let you focus on your business logic without having to maintain the underlying runtime environment and infrastructure. You only need to submit business-related source code in the form of functions.

OpenFunction features include:

• Cloud agnostic and decoupled with cloud providers' BaaS
• Pluggable architecture that allows multiple function runtimes
• Support both sync and async functions
• Unique async functions support that can consume events directly from event sources
• Support generating OCI-Compliant container images directly from function source code.
• Flexible autoscaling between 0 and N
• Advanced async function autoscaling based on event sources' specific metrics
• Simplified BaaS integration for both sync and async functions by introducing Dapr
• Advanced function ingress & traffic management powered by K8s Gateway API
• Flexible and easy-to-use events management framework

OpenFunction manages its components in the form of Custom Resource Definitions (CRD) throughout the lifecycle of a function, you can find more details in the Concepts section.

OpenFunction Events is OpenFunction's events framework, you can refer to OpenFunction Events for more information.
