Fn is an open-source, event-driven Functions-as-a-Service (FaaS) platform written in Go that runs anywhere Docker runs, on any cloud or on-premise. It treats any Docker container as a function, supports all programming languages, and can import and run AWS Lambda functions.

Use cases

• run serverless functions on my own infrastructure
• self-hosted alternative to AWS Lambda
• deploy functions as docker containers
• event-driven compute platform for any language
• run lambda functions outside aws
• build a faas platform on kubernetes or swarm

When to choose

• you need a self-hosted, cloud-agnostic serverless platform
• you want to run functions as plain Docker containers without vendor lock-in
• you need to port existing AWS Lambda functions to your own infrastructure
• you want multi-language function support via container images

When to avoid

• you want a fully managed serverless offering without operating infrastructure
• your team is standardized on a more actively developed FaaS like OpenFaaS or Knative
• you need deep integration with a single cloud provider's ecosystem
