WunderGraph is an open-source API developer platform that allows developers to build and deploy APIs with a focus on ease of use, scalability, and security. It's built using Golang and TypeScript and provides a framework for building microservices-based applications. The platform offers features such as multi-mode GraphQL schema composition, collision-free schema stitching via API namespacing, cross-API joins, and built-in RBAC. WunderGraph also has a strong focus on collaboration and community, with tools like WunderHub allowing developers to share APIs and collaborate on open-source projects. The platform is designed to be zero-ops, meaning that developers can simply "git push" their changes to deploy their APIs. With its emphasis on ease of use, scalability, and security, WunderGraph aims to revolutionize the way APIs are built and deployed.
