Package Manager for APIs (REST & GraphQL)

What it does

Build and run your supergraph with governance and no lock-in. WunderGraph Cosmo is an enterprise-ready platform for teams scaling from their first subgraph to thousands of daily operations.

Open-source router, self-host or managed, no usage penalties, audit logs & RBAC. Design with your team, create proposals, live traffic checks and get sign-off.

  WunderGraph – open-source API Developer Toolkit2022 · ▲63

  Dear HN Community. We're Bjorn, Dustin, Stefan & Jens, the founders of WunderGraph. More than two years ago, Jens started WunderGraph as a Side Project. The initial idea was to solve the problem of integrating multiple disparate DataSources into a single, unified API Layer. While solving this problem, Jens realized that his mental model of APIs was wrong. Most API tools treat APIs as abstract things or just endpoints, in a very imperative way. At some point, he realized that there's a better model to think about APIs: APIs are dependencies and we should treat them in a declarative way! And…

  Hi 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…
