fusio

Overview

Fusio is an open-source API management platform that transforms backend services into scalable API products. It acts as a bridge between internal infrastructure and external developers or AI systems. With native MCP integration, Fusio exposes APIs as tools for AI agents, enabling autonomous systems to interact with your backend logic. The platform offers features like database API gateway, microservice orchestration, custom API logic development, and AI-assisted development, making it comprehensive for both traditional API management and AI ecosystem integration.
