WunderGraph today launched Hub, a design and governance platform for engineering teams running GraphQL Federation at scale. Hub provides one integrated canvas for all teams across an organization to design APIs consumer-first and enforces schema change approvals, ownership checks, and consumer-impact validation before any change reaches a schema registry or codebase.

Why it matters

Federation tooling typically governs what happens after code exists, but Hub focuses on what comes earlier, when teams negotiate schema ownership, assess downstream impact, and approve changes before implementation begins. At scale, a two-day schema change can stretch into weeks when multiple teams must align across subgraphs, and Hub aims to streamline this process.

The details

Teams use Hub to validate schema proposals against governance rules, enforce subgraph ownership, and run consumer-impact checks. Every proposal carries consumer requirements, governance status, and an approval trail. If a proposal would break an existing consumer query, Hub flags it before any code is written. Hub applies the same governance rules to AI-generated proposals as to human-generated ones.

  • WunderGraph Hub has been in private beta since August 2025.
  • Hub is available today at wundergraph.com/hub.

What they’re saying

“Ownership, checks, and cross-team negotiations have become one of our biggest velocity bottlenecks.”

— Alexander Bandarchuk, Architect, eBay

“The Federation stack governs what happens after code is written. Hub puts governance where it needs to be: at the moment of design, before the change exists.”

— Jens Neuse, CEO, WunderGraph

What’s next

WunderGraph Hub is now available for all teams running GraphQL Federation at scale.

The takeaway

WunderGraph's new Hub platform aims to streamline the schema change approval process for organizations using GraphQL Federation, by providing a centralized platform for teams to negotiate ownership, assess downstream impact, and approve changes before implementation begins.
