Show HN: Nango – Open unified API for product integrations

Today customers expect every SaaS product to integrate with the other tools they use. Nango is a tool for engineers at SaaS companies to help them ship integrations fast, without compromising on the integration’s depth and quality. It supports more than 100 APIs out of the box.

Other integration companies have focused on building a lot of pre-built integrations. These are fast to ship and low maintenance, but they limit how deeply you can integrate with the external APIs.

We take a different approach: we make it easier for developers to build and maintain product integrations in code. This lets you create exactly the integration your customers need without compromising on speed and maintainability, and without having to build complex infrastructure (OAuth, retries, rate-limit handling, change detection, monitoring & logging, alerting, etc.).

Our platform has two layers: (1) An API-agnostic infrastructure built with Temporal and Postgres, and (2) lambda function-like integrations written in typescript by any developer.

Integrations are rarely more than 50 lines of code (here is an example: https://bit.ly/nango-example), thanks to the developer tooling we’ve built in: authentication, pagination, retries, change detection, rate-limit handling, monitoring, Slack alerts, etc.

We have pre-built integration templates you can clone and extend—or you can build entirely custom integrations. Your integrations live in your repo and are tested and deployed to Nango with a CLI.

In your product, you use a single API to interact with all your integrations. This lets you easily grow the available integrations with minimal code changes in your product.

As a community-driven project, anybody can contribute integration templates and APIs to the platform. In fact, more than 30% of the APIs we support today have been contributed by our community.

Nango grew out of a “universal OAuth” project called Pizzly and powers the integrations of 100+ SaaS products today. We have an active community of 800+ developers (https://nango.dev/slack).

All auth-related features are free forever, and we monetize with sync-related features. The entire code base and all integrations are source-available: https://github.com/NangoHQ/nango.

We hope Nango can help connect all SaaS products together and look forward to your feedback!
