Nango

Nango is an open-source product integrations platform that enables SaaS companies to build native integrations with third-party APIs quickly by providing pre-built OAuth flows, token management, rate limiting, and data syncing infrastructure that eliminates the repetitive plumbing work of building each integration from scratch. Its unified integration framework handles the complexity of hundreds of API quirks and authentication patterns so product teams can focus on integration logic rather than infrastructure. Product and engineering teams building SaaS products that need to integrate with dozens of third-party tools use Nango to ship native integrations ten times faster than building custom integration infrastructure for each.
