Cosmo by WunderGraph is an open-source GraphQL federation solution that unifies distributed APIs into a single federated graph, giving platform teams observability and control while enabling service teams to ship independently. Cosmo Streams converts existing event streams into GraphQL subscriptions, handling authorization, filtering, and fan-out in the Cosmo Router while keeping subgraphs stateless. Cosmo Connect extends the router with TypeScript to run custom logic inside the router, and Subgraph Check Extensions enforce custom schema rules before deployment.
