An open-source platform for building product integrations with AI, handling auth, proxy, and functions for 700+ APIs.
Nango is an open-source platform for building product integrations that supports over 700 APIs. It allows developers to write integration logic as TypeScript functions or generate them with AI, while handling authentication, execution, scaling, and observability. The platform solves the complexity of connecting products with external APIs and managing integration infrastructure at scale.
Developers and engineering teams building product integrations with external APIs, particularly those working on SaaS applications, AI agents, or data synchronization pipelines. It's also suitable for companies needing to manage OAuth flows, API credentials, and multi-tenant connections.
Developers choose Nango because it combines AI-generated integration code with full human control and type safety, while providing production-grade infrastructure that handles scaling, retries, and rate limits. Unlike black-box solutions, it offers transparent, editable code alongside managed auth for hundreds of APIs.

Nango's AI builder creates readable, type-safe TypeScript functions from natural language, allowing developers to review, edit, and version control integration logic, as emphasized in the README.
Handles OAuth, API keys, and token refresh for over 700 APIs with white-label flows and multi-tenant support, eliminating the need to build auth from scratch for each integration.
Provides per-tenant isolation, elastic scaling, automatic retries, and rate-limit handling, proven by processing billions of API requests for companies like Replit and Ramp.
Fully open source under the Elastic License, with options to self-host or use Nango Cloud, ensuring adaptability to different deployment and compliance needs, including SOC 2 Type II.
Integration functions must be written in TypeScript, which may not align with teams using other backend languages or preferring different programming paradigms, limiting flexibility.
The free self-hosting version has limited features, and managing the infrastructure requires additional overhead, as noted in the documentation about plan differences and configuration.
Relies on Nango's runtime for function execution, which could lead to vendor lock-in and make migration difficult if requirements change or costs escalate.
While AI aids code generation, customizing advanced functions, understanding the proxy system, and debugging production issues require significant time and expertise beyond basic use.
