In their own words
Fusio
Fusio is an open-source API management platform for connecting business logic and infrastructure to APIs. It is self-hosted and brings databases, microservices, and custom scripts behind a unified gateway that handles routing, authentication, and request validation. TypeSchema models add validation and generate OpenAPI specifications and client SDKs in multiple languages. A developer portal provides documentation, testing tools, and API keys; API monetization features can manage plans, quotas, subscriptions, and billing. AI-assisted development and AI/MCP integration are described as optional. Official adapters cover services and technologies such as AWS, Google Cloud, GraphQL, LDAP, MongoDB, Redis, SQL, Stripe, and SOAP. Worker runtimes are available for PHP, JavaScript, and Python, with SDKs listed for C#, Go, Java, JavaScript, PHP, and Python. Fusio also documents lifecycle management, access policies, and API analytics. Install options include a release archive, Composer, or Docker. The code is licensed under Apache 2.0. Fusio is available for free.
