## What it is
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

## Facets
- artifact type: service
- maturity: maintenance
- function: serverless, http-server, container-runtime, deployment, cli
- domain: cloud-computing, backend, self-hosted
- platform: windows, go, self-hosted, cloud
- tags: faas, functions-as-a-service, serverless-platform, lambda-compatible, event-driven, container-native, devops, containers, docker, kubernetes, linux, macos
