In plain words
WunderGraph is a GraphQL backend-for-frontend tool designed to aggregate multiple APIs into a unified GraphQL interface. It includes built-in OpenID Connect authentication and caching capabilities. The platform enables developers to combine disparate data sources and manage authentication centrally while improving API performance through intelligent caching. It is intended for teams building applications that need to integrate several APIs without managing authentication and data fetching complexity at the client level.

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. As your graph grows past 20 subgraphs, Cosmo keeps every team shipping independently, without stepping on each other. When every field has an owner and the graph is explorable, teams move faster. 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. Connect any service, stream real-time events, and expose your graph to AI agents, without adding infrastructure complexity. Backend teams write plain…from wundergraph.com

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…

Hey, I'm Jens, founder of WunderGraph. Over the years of working with REST & GraphQL APIs, I found that some aspects of using it are way too complicated. Here's a list of problems I believe could be abstracted away: - Aggregating multiple GraphQL, REST, etc. APIs into a simple to use API (Backend for Frontend) without writing code - adding Authentication & Authorization to APIs you don't have full control over - adding efficient and easy to use Caching to GraphQL APIs without writing code - adding persisted queries for security and performance reasons without making my application code and…

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…

Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t…
