At a Glance:
Nango is an open-source platform for building product integrations with AI, supporting 800+ APIs, managed OAuth, and a proxy for authenticated API requests deployable via TypeScript functions.
Overview:
Nango is an open-source platform that lets developers build, run, and maintain product integrations using AI and TypeScript functions. It provides managed authentication, token refresh, and an API proxy for 800+ APIs, removing the need for per-integration auth and credential handling. Users can write integration logic as functions and deploy them to Nango's production runtime, which handles execution, scaling, retries, and observability. An AI builder generates TypeScript integration code from natural language descriptions. The platform is designed to support AI tool calling, data syncing, webhook processing, and API unification across multi-tenant applications.
Key Decision Points:
Auth is fully managed: Handles OAuth, API keys, token storage, refresh, and multi-tenant connections for 800+ APIs, removing the need to build and maintain these flows.
Functions are written in TypeScript: Integration logic is expressed as TypeScript functions that run on Nango's production runtime, with built-in retries, storage, and observability—not a low-code or no-code abstraction.
AI code generation is reviewable: The AI builder generates TypeScript code you can review, edit, and version control instead of operating as a black-box service.
Supports self-hosting and compliance: Available as open source under an Elastic License, with self-hosted deployment options and SOC 2 Type II, HIPAA, and GDPR compliance.
CLI and API operable: Fully controllable via CLI and API, and compatible with any backend language, AI coding tools (Cursor, Codex, Claude Code), and agent SDKs (MCP, LangChain).
Core Features:
Managed Auth: Provides embedded, white-label OAuth flows, API key storage, and automatic token refresh across 800+ APIs with multi-tenant connection management.
Proxy: Routes authenticated API requests through Nango's infrastructure, resolving the provider, injecting credentials, and handling retries and rate limits.
Functions: Deployable TypeScript functions that execute integration logic on Nango's runtime with built-in API access, retries, storage, and observability.
AI Builder: Generates TypeScript integration functions from natural language use case descriptions, producing readable, version-controllable code with type safety and a testing framework.
Webhook Processing: Reliably receives and processes webhooks from external APIs as a supported integration pattern.
API Unification: Normalizes disparate external APIs into a universal schema defined by the user.
Use Cases:
Developers building AI agents that need to act on external APIs through tool calling or MCP.
Engineering teams that need two-way data syncing from external platforms into RAG pipelines or indexing systems.
Products that embed white-label OAuth flows and authenticated API access for multi-tenant end-users.
Teams standardizing on TypeScript who want AI-assisted generation of readable integration code they can review and maintain.
Open-Source Alternative Value:
Nango's open-source core provides a self-hostable integration platform with managed auth and a proxy for 800+ APIs, letting teams own their integration runtime rather than building these primitives or relying on closed-source alternatives. Developers receive reviewable TypeScript functions from its AI builder instead of opaque, generated integrations, and can operate everything via CLI and API. Self-hosted deployments support SOC 2 Type II, HIPAA, and GDPR compliance, making Nango an alternative for teams that require infrastructure control and auditable code while avoiding per-integration auth implementation.
