Lifecycle API management platform for federated GraphQL, covering schema registry, composition checks, routing, analytics, metrics and tracing.
Breaking a GraphQL schema into subgraphs owned by different teams solves an organizational problem and creates an operational one. WunderGraph Cosmo handles that second half, taking a federated graph from schema registry and composition checks through to routing, analytics, metrics and tracing.
Cosmo supports monolithic architectures as well as federated ones, so adopting it does not require having federated already. It runs fully on-premise or as a managed service, and the whole platform is Apache 2.0 licensed, which is what keeps the on-prem path free of vendor lock-in.
The repository is organized around who is evaluating it.
- Developer: compose a federated schema locally from several services and run the Cosmo Router.
- Architect: bring the entire platform up with Docker Compose to evaluate it for an organization.
- Platform engineer: deploy the platform to Kubernetes through the official Helm chart.
- CLI: a documented command line client for driving the registry and the rest of the platform.
- Managed service: a hosted Cosmo for teams that would rather not operate the control plane themselves.
Getting started is a clone, then picking the example that matches your role. The team publishes engineering writeups on scaling the router for the Super Bowl, minifying GraphQL ASTs, federated subscriptions over NATS and an efficient dataloading algorithm for federation, which are worth reading before committing. It suits organizations that want a unified graph across teams and intend to keep the control plane in their own hands.
Schema registry and analytics platform for GraphQL federation, available as a managed cloud service or self-hosted on your own infrastructure.
Hive Console registers GraphQL schemas and reports on how they are used, whether the API is federated, stitched or standalone. It closes the gap between publishing a schema and knowing what that change did, because what counts as a breaking change is decided from real operation data rather than a fixed rule.
The CLI publishes schemas and runs checks from any CI system, and the registry is served through a multi-zone Cloudflare CDN. Check results come back through Slack, GitHub or the application itself, the GitHub app can add status checks to pull requests, and the full history of changes stays available even for a composed schema.
Around the registry sit the pieces that show how a deployed API behaves.
- Usage monitoring: error rates and distribution, latency, request volume, operation counts and active clients.
- OpenTelemetry tracing: distributed traces beside usage data, with HTTP metadata and federation subgraph activity.
- App deployments: versioned persisted-document artifacts that can be activated, retired and served through the CDN.
- Alerting: Slack, Microsoft Teams or custom webhooks for schema and metric alerts.
- Governance: organization OIDC and audit log exports for teams that centralize access management.
The stack is Node.js and TypeScript with Fastify and GraphQL Yoga behind the API, React and Vite in the console, and PostgreSQL, Redis, ClickHouse and Kafka underneath. Run it as a managed service, or on your own infrastructure with the community Docker Compose configuration. It is MIT licensed and built in public by The Guild.
