Routebase

An API usually lives in several copies across OpenAPI files, documentation, mock servers, test suites and monitoring tools, and each copy drifts on its own schedule. Routebase removes that drift by generating every copy from one living OpenAPI spec, so a change to the contract reaches the docs, the API mocks and the API tests in a single publish. Teams design the API in a visual OpenAPI editor and review changes through spec branches with merge requests and breaking-change detection.

Contract tests run against any environment, and scheduled monitors compare the live API against the published contract. A built-in MCP server lets AI agents in Claude, Cursor or Visual Studio Code work with the same spec under the permissions of the team. Workspaces are hosted in the EU or the US, a free plan is available, and every new workspace starts with a 14-day Pro trial.
