Nango

Nango is an open-source unified API platform that simplifies building product integrations by providing a single interface to connect with over 250 third-party APIs. Rather than spending weeks building and maintaining individual API connections, developers use Nango's pre-built connectors and managed authentication layer to ship integrations in hours.

The platform handles the most painful aspects of integration development: OAuth flow management across providers, token refresh and credential storage, rate limit handling, pagination, and real-time webhook processing. Nango maintains a continuously updated library of 250+ pre-built API connectors spanning categories like CRM (Salesforce, HubSpot), communication (Slack, Microsoft Teams), file storage (Google Drive, Dropbox, Box), accounting (QuickBooks, Xero), HRIS (BambooHR, Workday), and many more.

Nango's unified API approach means developers write integration logic once using a consistent data model, and the platform translates requests to each provider's native API format. This dramatically reduces the code surface area for multi-integration products. The sync engine supports full and incremental data synchronization, allowing applications to maintain local copies of third-party data that stay current without polling.

As of early 2026, Nango powers integrations for thousands of companies ranging from startups to enterprises. The platform processes billions of API calls monthly across its managed infrastructure. The open-source core (available on GitHub with 10,000+ stars) can be self-hosted, while the managed cloud offering adds infrastructure scaling, monitoring dashboards, and enterprise support.

Key technical capabilities include a TypeScript-based integration scripting framework, built-in error handling with automatic retries, structured logging for debugging, and environment management for development/staging/production workflows. The platform provides both REST API and native SDKs for Node.js, Python, and other languages, making it accessible regardless of tech stack.

Nango is particularly well-suited for SaaS companies building customer-facing integrations, data pipeline teams needing reliable third-party data ingestion, and AI application developers who require structured data from external tools to feed into LLM workflows. Its managed OAuth eliminates the need to build and maintain authorization flows for each provider individually — a task that typically accounts for 40-60% of integration development time.
