Integration primitives

Nango provides a set of powerful primitives that you can combine to build any integration:

• Auth: Managed API authorization for 600+ APIs
• Proxy: Query APIs via Nango with credentials injection
• Functions: Build custom integrations in code with a scalable runtime

Flexible use cases

Flexible by design, Nango never constrains the integrations you need to build:

• Tool calling
• MCPs
• Data syncing & RAG
• Triggers
• Real-time webhooks
• Per customer configs
• Unified APIs

Why Nango?

We believe teams should build their own integrations, but with better primitives.

By leveraging Nango, developers can save weeks per integration:

• Fast: Avoid rebuilding hard infrastructure & per-API tools.
• Flexible: Code-based integrations with full access to external APIs.
• Dev-centric: API-first & infrastructure as code for mature development workflows.
• Reliable: Production-ready primitives from day one.
• Secure: Secure handling of credentials and user data.
• Observable: Full visibility into every API interaction.
• Modular: Use only what you need, without vendor lock-in.
• Proven at scale: Powers millions of users for companies like Replit, Mercor, Exa, etc.

Getting started

Authorize any API in minutes:

1. Configure an integration: Sign up (free, no credit card) then set up a new integration in the Integrations tab.
2. Authorize the API: On the Connections tab, create a new connection and complete the auth flow. Later, embed the auth flow in your product:

   nango.openConnectUI({ onEvent: (event) => { /* handle completion */ } });

3. Access the API: Retrieve the API credentials from your connection:

import { Nango } from '@nangohq/node';

const nango = new Nango({ secretKey: '<NANGO-SECRET-KEY>' });

const connection = await nango.getConnection(
    '<INTEGRATION-ID>',
    '<CONNECTION-ID>'
);

console.log(connection.credentials);

Next, follow the Auth implementation guide, make requests with the Proxy, or implement custom integrations with Functions.

Open-source vs. paid

Nango is offered under the Elastic license. Our Cloud and Enterprise Self-Hosted versions let you access all features, according to your plan. You can also self-host it for free with a limited feature set.
