Routebase

Your API doesn't live in one place. It lives in your design tool, your docs, your mocks, your tests and your monitoring, and every copy drifts on its own schedule. That drift is where the bugs come from, and no single tool fixes it, because the pain sits between them. Routebase makes them one living source. You design the OpenAPI spec in a visual editor, and the documentation portal, mock servers, contract tests and monitoring all derive from it. Change the spec, publish, and Routebase tells you what drifted against your live API, down to the field. You work on specs the way you work on code, with branches, review, merge and breaking-change detection. Every workspace also ships a built-in MCP server, so AI agents read and act on the same source of truth as the team, under the same permissions.
