Nango (https://github.com/NangoHQ/nango) provides pre-built OAuth flows, secure token storage and automatic refreshes for 40+ APIs and counting. Why we built Nango: We built Nango to solve the pain of accessing OAuth APIs. Despite OAuth being a standard protocol in theory, it remains a major burden to implement it, even with the help of a library. You still need to add endpoints and logic to your app for the server-side dance, implement token refreshes, build & secure your token storage, deal with redirects on the frontend etc. But the worst part is that (almost) every…

Hey HN! Happy to finally launch Stack. We made it because we like to put apps into production quickly, and authentication & user management was taking up way too much time. We have components like and that automatically adapt to whatever theme & design system you're using. Check the blog post to see the example with Radix UI and Joy UI. Also, there's an admin dashboard for monitoring and editing accounts. Stack is 100% AGPL/MIT-licensed, so you can self-host it. Cheers!

Hey HN, we’ve been working on a way to simplify authentication with third-party APIs. This started because my co-founder andreterron (https://news.ycombinator.com/user?id=andreterron) and I both built personal dashboards to track different health and productivity metrics, but it’s such an annoying chore to integrate with new APIs. First you read their docs to learn their authentication method, then build and deploy a custom server to receive OAuth callback requests or deal with CORS, register an app with them, then finally you can send the first request to their API. After the…
