Announcing Fn–An Open Source Serverless Functions Platform

We are very excited to announce our new open source, cloud agnostic, serverless platform–Fn.

The Fn project is a container native Apache 2.0 licensed serverless platform that you can run anywhere–any cloud or on-premise. It’s easy to use, supports every programming language, and is extensible and performant. 

We've focused on making it really easy to get started so you can try it out in just a few minutes and then use more advanced features as you grow into it. Check out our quickstart to get up and running and deploying your own function in a few minutes.


The Fn Project is being developed by the same team that created IronFunctions. The team pioneered serverless technology and ran a hosted serverless platform for 6 years. After running billions of containers for thousands of customers, pre and post Docker, the team has learned a thing or two about running containers at scale, specifically in a functions-as-a service style.

Now at Oracle, the team has taken this knowledge and experience and applied it to Fn.


Fn has a bunch of great features for development and operations.

  • Easy to use command line tool to develop, test and deploy functions
  • One dependency: Docker
  • Hot functions for high performance applications
  • Lambda code compatibility - export your Lambda code and run it on Fn
  • FDK's (Function Developer Kit) for many popular languages
  • Advanced Java FDK with JUnit test framework
  • Deploy Fn with your favorite orchestration tool such as Kubernetes, Mesosphere and Docker Swarm
  • Smart load balancer built specially for routing traffic to functions
  • Extensible and modular, enabling custom add-ons and integrations

The project homepage is fnproject.io but all the action is on GitHub at github.com/fnproject/fn

We welcome your feedback and contributions to help make Fn the best serverless platform out there.
