The Fn Serverless Project is Now Available

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

The Fn project is a container native serverless platform that you can run anywhere —on 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.
  • FDK’s (Function Developer Kit) for many popular languages.
  • * Advanced Java FDK with JUnit test framework.
  • * Lambda code compatibility — export your Lambda code and run it on Fn.
  • 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 is available on GitHub today at:

We welcome your feedback and contributions to help make Fn the best serverless platform out there. It’s an open project with an Apache 2.0 license, so use it however you wish!
