How to deploy Cosmo on Kubernetes for production?

Use the official Helm chart provided in the examples for platform engineers, which includes configurations for deploying the entire Cosmo stack. Ensure you have Kubernetes expertise and refer to the docs for scaling and monitoring best practices.

WunderGraph Cosmo vs Apollo Studio: which is better for self-hosting?

Cosmo is superior for self-hosting due to its open-source Apache 2.0 license and lack of vendor lock-in, while Apollo Studio is a managed service with a more mature ecosystem. Choose Cosmo if you need full control and on-premises deployment.

Does Cosmo support GraphQL subscriptions in federated setups?

Yes, Cosmo supports federated GraphQL subscriptions using technologies like NATS, as detailed in blog posts about event-driven architecture. It enables real-time data streaming across distributed services.

What are the performance benchmarks for Cosmo Router?

Cosmo Router is optimized for high traffic, with blog posts discussing scaling for events like the SuperBowl and algorithms for query minification. Specific benchmarks depend on configuration but focus on low latency and efficient resource usage.

How to integrate Cosmo with existing CI/CD pipelines?

Use the Cosmo CLI for schema checks and registrations in CI steps, and leverage the schema validation features to prevent breaking changes. The docs provide guidance on automating deployments with tools like GitHub Actions or Jenkins.

Is Cosmo suitable for monolithic GraphQL architectures?

Yes, Cosmo supports both monolithic and federated GraphQL, but its primary strength is in federation. For monolithic setups, it might be overkill unless you need advanced observability or plan to transition to federation later.

WunderGraph Cosmo — GraphQL Federation Platform

What is WunderGraph Cosmo?

WunderGraph Cosmo is an open-source platform for managing the entire lifecycle of federated GraphQL APIs. It provides tools for schema registry, composition validation, analytics, metrics, tracing, and routing, enabling organizations to build and maintain large-scale federated graphs efficiently. It solves the problem of coordinating GraphQL schemas across multiple teams and services while ensuring consistency and observability.

Target Audience

Platform engineers, architects, and development teams building or managing federated GraphQL APIs at scale, particularly in organizations with multiple services and teams.

Value Proposition

Developers choose Cosmo because it offers a complete, self-hostable alternative to proprietary solutions like Apollo Studio, with no vendor lock-in, full observability features, and support for both federated and monolithic GraphQL architectures under a permissive open-source license.

Overview

The open-source solution to building, maintaining, and collaborating on GraphQL Federation at Scale. The alternative to Apollo Studio and GraphOS.

Use Cases

Best For

Managing federated GraphQL schemas across multiple teams and services
Implementing observability and analytics for GraphQL APIs in production
Self-hosting a complete GraphQL federation platform on-premises or in private cloud
Scaling GraphQL query routing and execution for high-traffic applications
Evaluating open-source alternatives to Apollo Studio and GraphOS
Building a unified API layer for internal and external consumers using GraphQL Federation

Not Ideal For

Small teams or startups with a single GraphQL service and no plans for federation
Projects that require rapid prototyping with minimal setup; Cosmo's Docker/Helm deployment adds complexity
Organizations using primarily REST APIs with no GraphQL adoption or integration needs
Teams lacking dedicated platform engineering resources for ongoing self-hosting maintenance

Pros & Cons

Pros

Comprehensive Federation Management

Centralized schema registry with validation and composition checks ensures consistency across distributed teams, as highlighted in the focus on federated GraphQL lifecycle management.

Built-in Observability Suite

Includes metrics, tracing, and analytics for monitoring GraphQL performance, backed by blog posts on scaling for high-traffic events like the SuperBowl.

Deployment Flexibility

Supports both self-hosting on-premises and managed cloud service under Apache 2.0 license, avoiding vendor lock-in as emphasized in the philosophy section.

High-Performance Query Router

Cosmo Router is optimized for scalability with features like query minification and efficient data loading algorithms, detailed in technical blog posts.

Cons

Complex Initial Setup

Deploying the full platform requires Docker Compose or Helm charts, which can be time-consuming and daunting for teams without DevOps expertise, as seen in the role-based examples.

Steep Learning Curve

Demands in-depth knowledge of GraphQL federation concepts and platform architecture, making it less accessible for teams new to distributed GraphQL systems.

Operational Overhead

Self-hosted instances necessitate ongoing maintenance, updates, and monitoring, adding to the team's responsibilities compared to fully managed alternatives.

Open Source Alternative To

WunderGraph Cosmo is an open-source alternative to the following products:

G

GraphOS

GraphOS is Apollo's cloud platform for managing GraphQL APIs, providing analytics, schema management, and federation tools.

Apollo Studio

Apollo Studio is a cloud platform for GraphQL development that provides tools for schema management, performance monitoring, and collaboration.
