Everything you need to know about APIgen, generated source code, and pricing.
APIgen generates complete, customizable REST APIs powered by Fusio alongside a modern Angular CRUD frontend interface.
You can design schemas manually or use our AI Architect to convert plain natural language descriptions into structured types, properties. The output is clean, production-ready source code you can host yourself or extend as a solid foundation. Take a look at our demo page to see reference apps.
Unlike typical Backend-as-a-Service (BaaS) platforms that lock you into a proprietary backend or runtime, APIgen uses a generative model. You design entities in our generator, or prompt our AI, and we synthesize complete, standalone PHP/Fusio and TypeScript/Angular source code.
You own 100% of the generated code with zero vendor lock-in, meaning you can deploy to your own servers, customize business logic, and modify endpoints freely.
Getting started is free, you simply need to register an account to start building and generating schemas. For power users and teams building larger multi-entity projects, basic and pro plans are available.
Fusio is open-source software (Apache 2.0). If you'd like to support the ongoing development of the open-source ecosystem, please consider making a donation.
If you encounter bugs, template generation issues, or unexpected errors in the output, please open an issue directly on the corresponding GitHub demo repository:
