About WunderGraph API

WunderGraph Cosmo is an open-source API federation platform designed for platform engineering teams to manage and scale GraphQL APIs across various services and teams. It provides tools and infrastructure to unify fragmented API contracts (GraphQL, REST, gRPC, Kafka) into a single, observable model, enabling faster and safer API changes with built-in guardrails and observability. Cosmo aims to simplify the complexities of GraphQL federation, offering solutions for event-driven subscriptions, integrating existing backends without requiring GraphQL knowledge, and streamlining developer workflows. The platform includes a high-performance Go-based router, a Schema Registry for version control and validation of API schemas, and tools like Cosmo Connect for integrating gRPC services into a federated graph. It supports both GraphQL Federation v1 and v2, is language-agnostic, and can be deployed on-premise or in a hybrid model for compliance. Cosmo also incorporates AI-driven workflows for enhanced productivity, security, and compliance, making it suitable for modern API infrastructures.
