## What it is
Fusio is a self-hosted, open-source API management platform and gateway written in PHP that turns databases, microservices, and custom logic into professional REST API products. It includes a developer portal, SDK generation, monetization, analytics, and native MCP support for exposing APIs to AI agents.

## Use cases
- expose a legacy mysql or postgresql database as a rest api
- set up an api gateway in front of my microservices
- self-host an api management platform with a developer portal
- generate client sdks and openapi docs from my api
- monetize my api with subscription plans and quotas
- expose my backend logic as mcp tools for ai agents
- add rate limiting and authentication to my apis

## When to choose
- you want a self-hosted alternative to commercial API management platforms
- you need to expose databases or microservices as managed REST APIs with docs and keys
- you want to monetize APIs with plans, quotas, and billing at the gateway
- you want to make your backend logic available to AI agents via MCP

## When to avoid
- you only need a lightweight HTTP router or micro-framework inside a single app
- your stack is not PHP-friendly and you prefer gateways like Kong or Tyk
- you need a fully managed SaaS API gateway rather than self-hosted infrastructure
