Fusio

Self-Hosted API Management for Builders.

📡

Unified API Gateway

Connect databases, microservices, or custom scripts into a standardized API. Fusio handles the infrastructure routing, authentication, and request validation so you can focus on core execution logic.

🧠

Schema-Driven Automation

Define your data models once using TypeSchema. Fusio uses this metadata to enforce strict validation and automatically generate OpenAPI specifications and multi-language client SDKs.

Lifecycle Management

Manage the entire API ecosystem with a built-in developer portal, granular rate limiting, and a native monetization layer to handle subscriptions and billing directly at the gateway.
