What is Fusio?

Fusio is an API gateway and backend platform written in PHP. You describe logic as actions, either PHP classes or worker actions in JavaScript or Python, and bind them to HTTP operations. It can expose MySQL or PostgreSQL tables as REST endpoints and route traffic to microservices. Around that sit a self-service developer portal, generated client SDKs, subscription plans with quotas, and usage analytics. Since version 7 an agent can draft actions from a text prompt using Ollama, ChatGPT or Gemini, and APIs can be offered to AI tools through the Model Context Protocol.

Good fit if

  • You want to publish an existing database or service as a documented API for outside developers.
  • You plan to charge for API access and need plans and quotas in the same tool.
  • Your team already writes PHP.

Look elsewhere if

  • You only need a high-throughput gateway in front of existing services: Kong or Tyk.
  • You want instant GraphQL over a database: Hasura.

Before you adopt it

Fusio moved from AGPL-3.0 to the Apache-2.0 license in July 2023, and the repository has no paid parts; the marketplace for apps and actions is a separate service. It belongs to the apioo organization, but a single developer made every commit in the last 90 days. Installation needs PHP, a MySQL, PostgreSQL or SQLite database, migrations and an Nginx or Apache setup for production; a web installer is also available.
