About Nango

Nango is an open-source platform that helps teams build integrations into their products. It covers more than 1,000 APIs and is compatible with any backend language, AI coding tool or agent SDK. Integration logic is written as TypeScript functions, or generated by AI from a description, and deployed to Nango's production runtime, which handles authentication, execution, scaling and observability.

It is organized around three primitives. Auth provides managed OAuth, API keys and token refresh, with a white-label flow you can embed in your app, plus credential storage and multi-tenant connection management. The proxy sends authenticated requests on behalf of your users, resolving the provider, injecting credentials and handling retries and rate limits. Functions run integration code with API access, retries, storage and observability built in.

The README lists use cases including AI tool calling and MCP, one-way and two-way data syncing for RAG pipelines, webhook processing and API unification into your own schema. A hosted runtime is available, and the repository lists the licence as Other. Topics point to OAuth, access and refresh tokens and unified APIs.
