Routebase is the single source of truth for your APIs. You design the OpenAPI spec once in a visual editor, and the documentation portal, mock servers, contract tests, and monitoring all derive from it.
Change the spec, publish, and Routebase catches what drifted before your consumers do, with field-level diffs against your live API. 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. It is built for the teams that own an API: backend developers who write the contract, frontend engineers who build against mocks, and QA who run the suites in CI.
