Nango

Nango is a developer infrastructure platform designed for building product integrations, enabling teams to authorize and access APIs on behalf of their customers. The platform provides pre-built authentication for over 500 APIs, allowing developers to integrate their products and AI agents with external services using a code-first approach with full control and a powerful SDK.

• API Auth for 500+ APIs provides embedded, white-label authentication UI with secure credential management, automatic token refreshing, and webhook notifications when credentials become invalid.

• Two-way Syncing enables continuous data synchronization from external APIs to your application, with support for reading and writing any data with full platform support.

• Request Proxying seamlessly injects credentials into API requests, eliminating the need to manually handle authentication for each request.

• Actions & Functions allow you to encapsulate use cases into reusable actions and run custom integration logic in production with auto-scaling infrastructure.

• LLM Tool Calling & MCP Server exposes your integrations as tools to any LLM or AI agent, making it easy to build AI-powered workflows that interact with external services.

• Webhooks let you listen to webhooks from any API with a universal interface, simplifying event-driven integrations.

• Observability provides detailed real-time logs, metrics, and OpenTelemetry integration for full visibility into every interaction with external APIs.

• Local Development keeps integrations in your codebase, tracked with git, and testable locally using the CLI before deploying to Nango's production infrastructure.

To get started, sign up for a free account, install the Nango CLI with npm i -g nango, and create your first integration using nango create. The platform supports AI-assisted development, allowing you to use any IDE and AI agent to generate integrations. Deploy your integrations with nango deploy and Nango handles running them reliably at scale with sub-100ms execution times and automatic scaling for traffic spikes.
