Nango is an open-source integration platform that connects products and AI agents to over 800 APIs, handling auth, token management, and multi-tenant connections.

It provides three core primitives—Auth, Proxy, and TypeScript-based Functions (including AI-generated functions)—to build, run, and scale integration logic on a production runtime. Nango supports use cases such as AI tool calling, data sync, webhooks, unified APIs, and per-customer configuration, and can be run on Nango Cloud or self-hosted under an Elastic License with both free and paid feature tiers.
