What WunderGraph does

WunderGraph, Inc. is a Delaware-incorporated, Miami-headquartered software company founded in 2020 that builds an open-source GraphQL Federation platform targeted at platform engineering teams operating supergraphs at scale. Its core product, Cosmo, is an Apache 2.0 licensed federation runtime built in Go that routes queries through a high-performance gateway, manages schemas in a registry, and supports multi-protocol unification across GraphQL, REST, gRPC, and event streams via sub-products including Cosmo Connect, Cosmo ConnectRPC, and Cosmo Streams. Notable technical components include a Router claimed to deliver 8x better P99 latency than Apollo Router, Dataloader 3.0 for batch execution, AST-JSON transformations, a Cache Warmer with up to 99% latency improvement, and an Event-Driven Federated Subscriptions (EDFS) architecture.

The company added a second product, WunderGraph Hub, which entered general availability in March 2026 after a private beta with design partners eBay, SoundCloud, and On The Beach. Hub provides a collaborative canvas, AI-assisted schema design, ownership management, and traffic-aware validation for federated graph governance. In March 2026, WunderGraph also launched an MCP Gateway connecting GraphQL APIs to AI agents and IDEs (ChatGPT, Claude, Cursor, Windsurf, VSCode) via the Model Context Protocol.

WunderGraph operates a hybrid go-to-market: a self-serve product-led growth motion via free-tier Cosmo Cloud signup (no credit card required) and an enterprise field-sales motion with quote-based pricing. The company has raised $10.5 million in total funding across a $3M seed (Aspenwood Ventures, April 2023) and a $7.5M Series A (Karma Ventures lead, with eBay Ventures and Aspenwood Ventures, March 2025), and reports 30+ enterprise customers spanning e-commerce, audio streaming, marketing technology, fashion retail, travel, gaming, and healthcare. Certifications include SOC 2 Type II, ISO 27001, and HIPAA.

Core offering

WunderGraph sells a complete GraphQL Federation stack composed of Cosmo (an open-source Apache 2.0 federation runtime with a high-performance Go-based router, schema registry, and analytics) and Hub (a design and governance platform for federated schemas with collaborative canvas and AI-assisted schema design). The platform is delivered as both a self-hostable open-source distribution via GitHub and a managed SaaS (Cosmo Cloud), with supporting modules for gRPC/REST federation (Connect, ConnectRPC), AI/LLM integration (MCP Gateway), and event-driven subscriptions (Cosmo Streams).

Product overview

WunderGraph provides a unified GraphQL Federation stack consisting of two main platforms: Cosmo (open-source federation runtime) and Hub (design and governance layer). Cosmo includes the high-performance Router/gateway, Schema Registry, and support for multiple protocols through Connect, ConnectRPC, MCP Gateway, and Streams modules. Hub provides collaborative visual canvas, AI-powered schema design, ownership management, traffic-aware validation, and automated governance workflows. The platform targets enterprises running GraphQL Federation at scale, offering both self-hosted open-source deployment (Apache 2.0) and managed Cosmo Cloud service, with key differentiators including 8x better latency than Apollo Router, native support for gRPC integration, AI-ready MCP interfaces, and event-driven subscriptions.

Direct peers

• The GraphQL Foundation (GraphQL Yoga, Hive): The Guild develops open-source GraphQL tools including GraphQL Yoga (server) and GraphQL Hive (schema registry and operational tools). Like WunderGraph Cosmo and Hub, Hive targets federated GraphQL governance and observability, and the two compete for open-source federation mindshare.
• Hasura: Hasura provides a managed GraphQL and REST API platform that auto-generates APIs from databases with federation and governance capabilities. It overlaps with WunderGraph Cosmo as a GraphQL API platform targeting platform engineering teams but uses a different core architecture (database-driven) instead of federated subgraph composition.
• Apollo GraphQL: Apollo GraphQL operates GraphOS, the dominant GraphQL Federation platform including a Router, schema registry, and governance tooling. WunderGraph explicitly positions Cosmo as an open-source alternative to Apollo's router and Federation stack, citing 8x performance improvement.
• Tyk: Tyk offers an open-source API gateway with first-class GraphQL support alongside REST and gRPC. Like WunderGraph Cosmo, it serves platform engineering teams building multi-protocol API infrastructure with self-hosted and managed deployment options.

Broad incumbents

• Subgraph-native: StepZen / IBM: StepZen, originally an independent GraphQL federation startup, was acquired by IBM. It overlaps with WunderGraph Cosmo's value proposition of unifying multiple data sources (REST, GraphQL, databases) behind a single GraphQL endpoint, positioning it as a broader incumbent in the GraphQL federation space.
• Netflix DGS (now Spring GraphQL): Netflix DGS is an open-source GraphQL framework now under Spring for Java/Kotlin services, with federation support via the GraphQL Java implementation. It's a broader-incumbent comparable to WunderGraph Cosmo on the federation subgraph and schema-definition layer, though with narrower scope (server-side only).
• Kong Inc. Kong provides a broad API gateway and service mesh platform used for managing REST, GraphQL, and gRPC at enterprise scale. Compared to WunderGraph's GraphQL-Federation-first Cosmo, Kong is a broader portfolio play serving API infrastructure across multiple protocols and deployment modes.
• AWS AppSync: AWS AppSync is AWS's fully managed GraphQL service with built-in caching, real-time subscriptions, and integration with AWS data sources. As a hyperscaler-incumbent alternative, it overlaps with WunderGraph Cosmo Cloud on managed GraphQL routing and federation, though typically constrained to AWS-native data sources.

Emerging players

• Grafbase: Grafbase is an early-stage GraphQL Federation platform offering a managed GraphQL API gateway with schema composition. It is a direct emerging competitor to WunderGraph Cosmo for developers building federated APIs but with smaller installed base and narrower enterprise traction.
• Solo.io: Solo.io provides API gateway and service mesh solutions with Envoy-based routing for cloud-native and AI workloads. It overlaps with WunderGraph Cosmo's multi-protocol API routing and is increasingly positioning for AI agent connectivity similar to Cosmo's MCP Gateway.
