## What it is
fx is a self-hosted Function as a Service (FaaS) tool that turns stateless functions into container-based HTTP services in seconds. It supports deploying functions written in many languages (Go, Node, Python, Ruby, Java, Rust, PHP, and more) onto either a Docker host or a Kubernetes cluster.

## Use cases
- run serverless functions on my own server
- deploy a python function as an http api
- self-hosted aws lambda alternative
- turn a stateless function into a containerized service
- deploy functions to a kubernetes cluster
- faas tool supporting multiple programming languages

## When to choose
- you want a lightweight, self-hosted FaaS without the complexity of OpenFaaS or cloud offerings
- you need to deploy functions in many different languages quickly
- you already run Docker or Kubernetes and want simple function deployment

## When to avoid
- you need production-grade autoscaling, monitoring, and event triggers at scale
- you prefer a managed serverless platform like AWS Lambda
- you need an actively developed project with frequent releases
