Routebase is an API lifecycle management platform that lets you design, mock, test, document, and govern your APIs from a single OpenAPI spec. Instead of juggling separate tools and keeping docs in sync, Routebase makes the spec the single source of truth. It includes a visual editor, automatic mock server, test suites, docs portal, and a built-in MCP server for AI agents.
APIs get messy: specs drift, docs go stale, tests break, and agents can't access your endpoints safely. Routebase solves this by tying everything to one living spec. When you change the contract, mocks, tests, and docs update automatically. This removes manual sync work and lets frontend and backend teams build in parallel from day one.
Routebase is for API-first product teams, platform engineers, and developer experience leads who want to operationalize the whole API lifecycle. It's also useful for teams adopting AI agents because each workspace ships an MCP server with 80+ tools, letting agents discover, call, and test APIs under team permissions. It's not for individuals who just need a simple REST client or a one-off mock.
Teams use Routebase to design a new API contract before writing code, spin up mocked endpoints so frontend and backend work in parallel, run scheduled test suites against dev and production environments, publish developer docs that never drift, and let AI agents interact with their APIs safely. Pricing starts at $9 per user per month (annual billing), with a free tier and a 14-day Pro trial.
