ClaimedDesign, test, mock and document APIs from one OpenAPI spec

The Bottom Line
- Best for
- Backend and platform teams of 5-50 engineers keeping an API's docs, mocks and tests in sync, and wanting AI agents on the same spec.
- Price
- From $9/mo (free plan available). Compare plans
Key facts
- Design the API once, and the same OpenAPI description drives docs, mocks and tests, with a native MCP server covering the full feature set so agents work the same spec as the team
Pros
- Docs, mocks and contract tests are generated from the same OpenAPI description, so they cannot drift apart
- Native MCP server covering the full feature set, so agents work the same workspace as the team under the same role permissions
- Visual API designer with spec branches and merge requests, so a breaking change meets a reviewer before it ships
Cons
- Teams whose APIs are GraphQL, gRPC or SOAP, and anyone who needs a self-hosted install, because Routebase is SaaS with EU or US data residency.
What is Routebase?
Routebase runs the API lifecycle from one OpenAPI description: visual designer with spec branches and merge requests, spec-generated mock servers, test suites with contract tests and OWASP scanning, a docs portal on your own domain, and monitors that report field-level drift against the live API. No existing OpenAPI file needed, start empty or import a Postman/Insomnia collection; test cases work without a spec. Every workspace ships an MCP server that covers the full feature set of the product. EU or US hosting.
Available on: Web, API, Desktop, CLI

Routebase FAQ
How does Routebase help teams maintain consistency across API design, documentation, and testing?
Routebase generates docs, mocks, and contract tests from the same OpenAPI description, so they cannot drift apart. This ensures that the API documentation, mock servers, and test suites always match the current specification.
How does Routebase compare to Postman for API lifecycle management?
Unlike Postman, Routebase runs the entire API lifecycle from a single OpenAPI description, generating docs, mocks, and contract tests that stay in sync. Routebase also includes a native MCP server that covers the full feature set of the product and offers EU or US data residency on every plan.
Which API types or deployment models does Routebase not support?
Routebase is a SaaS product with EU or US data residency and does not offer a self-hosted install. Teams using GraphQL, gRPC, or SOAP will find that Routebase is built around OpenAPI and may not fit their workflow.
Which teams benefit most from using Routebase?
Teams that manage REST APIs and need a unified workflow from design to monitoring benefit most from Routebase. It is especially useful for teams that want to keep documentation, mock servers, and contract tests in sync without manual effort.
How is Routebase priced?
Routebase is available on a free tier, with paid plans for more usage and features. Pricing is based on usage and feature access, and every plan includes EU or US data residency chosen per organization.
Can Routebase import existing API collections from other tools?
Routebase can start empty or import a Postman or Insomnia collection. No existing OpenAPI file is needed, and test cases can work without a spec.
Does Routebase include a documentation portal on a custom domain?
Routebase provides a docs portal on your own domain, generated from the OpenAPI description. This ensures documentation is always up to date with the spec.
How does Routebase handle API monitoring and drift detection?
Routebase monitors live APIs and reports field-level drift against the OpenAPI description. This allows teams to detect when the actual API behavior diverges from the specification.
Can I use Routebase for API testing without an OpenAPI spec?
Yes. Test cases in Routebase work without a spec, so you can start with plain HTTP requests and assertions or import a Postman or Insomnia collection. Once an OpenAPI description exists, contract tests compare the live API against it and report field-level drift.
