WunderGraph Hub

WunderGraph

WunderGraph Hub is a platform designed to help development teams design, manage, and evolve APIs together within a structured workflow. It acts as a coordination layer for API development, allowing teams working across distributed services to collaboratively design schemas, propose changes, and align on API capabilities before implementation begins. It provides a visual design canvas where developers, API owners, and consumers can define capabilities, model schema structures, and discuss requirements in a shared workspace. Once a design is created, Hub automatically generates schema proposals and organizes feedback from stakeholders through governed workflows, ensuring that proposed API changes are reviewed, approved, and documented before being deployed. This approach enables teams to shift from informal communication and fragmented documentation toward structured collaboration with traceable decision-making.

Routebase

Routebase GmbH

Routebase is the single source of truth for your APIs. Design your OpenAPI spec once in a visual editor — no hand-edited YAML — and your documentation portal, mock servers, contract tests, and monitoring all derive from that one spec. Change the contract, publish, and Routebase catches what drifted before your consumers do: it validates live responses against the spec and flags every divergence with field-level diffs — missing fields, type mismatches, undocumented additions. Work on specs the way you work on code: branch, review, merge, with breaking-change detection before anything ships. Publish a docs portal on your own custom domain. Spin up realistic mocks so frontend and backend build in parallel. Run contract and security tests against any environment. Every workspace also ships a built-in MCP server, so your AI agents read and act on the same source of truth, under your team's permissions — no glue code.
