How it works
Nango gives you 2 primitives that cover every integration pattern:Auth
Embed a white label, managed auth flow in your app. Nango handles OAuth, API keys, token refresh, and credential storage for 700+ APIs. Never deal with auth plumbing again.
Functions
Write integration logic as TypeScript functions and deploy them to Nango. Functions execute on a production runtime with built-in API access, retries, storage, and observability. Use the AI builder to generate them from a description of your use case.The runtime handles per-tenant isolation, elastic scaling, and predictable execution. Deploy like you deploy your app, with CI/CD, git, and a CLI.
What you can build
Nango supports every common integration pattern:AI tool calling & MCP
Give AI agents the ability to act on external APIs.
Data syncing
One or two-way sync for RAG pipelines, indexing and triggers.
Webhook processing
Receive and process webhooks from external APIs reliably.
API unification
Normalize APIs to your own universal schema.
Actions
Write data and execute operations on behalf of your users.
Per-customer config
Customize integration behavior for each of your customers.
Why Nango?
AI-generated, human-controlled code. Nango’s AI builder generates TypeScript integration functions from natural language. Unlike black-box solutions, you get readable code you can review, edit, and version control. With full type safety and a built-in testing framework. Production-grade infrastructure. Nango processes billions of API requests. The runtime provides per-tenant isolation, elastic scaling, automatic retries, and rate-limit handling. Battle-tested by hundreds of companies in production. Auth for 700+ APIs, out of the box. OAuth flows, token refresh, credential storage, and multi-tenant support handled for you. Connect to any API without building auth from scratch. Open source and self-hostable. Nango is fully open source. Run it on Nango Cloud or self-host on your own infrastructure. SOC 2 Type II, HIPAA, and GDPR compliant. Fits your workflow. Fully operable via CLI and API. Compatible with any backend language or framework, AI coding tools (Cursor, Codex, Claude Code), and agent SDKs (MCP, LangChain).Get started
