Open-source OAuth service for 40+ APIs
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…

In plain words
Nango is an open-source OAuth service that handles authentication flows, token storage, and automatic refresh for over 40 APIs. Built for developers integrating multiple third-party services, it eliminates the complexity of implementing OAuth manually by providing pre-built templates that account for each API's specific quirks and non-standard behavior. The service manages the server-side authentication dance, token security, and frontend redirects, letting developers focus on their core application logic.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
