Routebase is a hosted service for API design, mocking, testing, documentation, monitoring and MCP capabilities, built around a shared specification. Its visual editor supports OpenAPI endpoints, schemas and versions. Publishing a version creates a documentation portal and mock server, while tests and monitors validate it. Scheduled monitors compare live API responses with the specification and flag field-level differences. A native Model Context Protocol server lets agents design, lint and test APIs through the same interface. Integrations include event-driven webhooks, Slack and Microsoft Teams alerts, scoped API keys and MCP access for AI agents. Pro includes governance and security scanning; documentation describes checks against the OWASP API Security Top 10. Workspace data can be hosted in the EU or US, chosen when creating the workspace. Routebase offers a free plan and a 14-day trial; paid plans start at $9/user/mo billed annually. It has no on-premise or self-hosted edition. Desktop apps are available for macOS 10.15+ and Windows 10 or later; MCP CLI builds are available for macOS, Windows and Linux.
Who it is for
Routebase suits teams designing and maintaining OpenAPI services that want specification-based docs, mocks, tests and monitoring. Its MCP server may also suit teams using agents to work with APIs.
What is good
- Free plan includes OpenAPI import and export.
- Published versions generate a docs portal and mock server.
- Monitors flag response differences at field level.
- Workspace hosting can be set to EU or US.
- Pro includes governance and security scanning.
What to know first
- No on-premise or self-hosted edition is offered.
- Free plan is limited to one user and two projects.
- Paid plans start at $9/user/mo billed annually.
- Service availability averages 99% per calendar year.
Verdict
Routebase ties API artifacts and checks to a shared OpenAPI specification, with monitoring and MCP features included. It is hosted only, so teams requiring self-hosting should look elsewhere; the Free plan is the smallest starting point.
