Routebase
Your API drifts across several tools. Routebase keeps design, docs, mocks, contract tests and monitoring in one living source.

Product Overview
Routebase keeps API design, documentation, mocks, contract tests, and monitoring in sync by treating one OpenAPI spec as the single source of truth. Teams design the contract in a visual OpenAPI editor (or import an existing spec), then publish a version that automatically generates the docs portal and mock server, while tests and monitors validate against that same version.
When live behavior diverges from the spec, Routebase flags drift with field-level diffs, helping teams catch issues before consumers are impacted. It also supports branch/review/merge workflows for specs and includes an MCP server so agents can read and act on the same source of truth.
Key features
- Visual OpenAPI editor for designing API contracts without hand-edited YAML
- Publish a spec version to generate the docs portal and mock server from the same source
- Built-in test runner that runs suites against the published spec version
- Drift monitor that replays live responses and reports divergence as field-level diffs
- Branch, review, and merge workflows for specs with breaking-change detection before shipping
- Built-in MCP server so agents can read and act on the same spec under team permissions
How Routebase works
- 1
Design API in visual editor
Create or import an OpenAPI 3.1 contract in Routebase’s visual OpenAPI editor.
- 2
Publish spec version for outputs
Publish a version so Routebase generates the docs portal and mock server, with tests and monitors targeting that same version.
- 3
Validate, monitor, and catch drift
Run contract suites (e.g., in CI) and use drift monitoring to replay live responses and report field-level diffs.
Use cases
- An API team updates a contract field and publishes a new spec version; Routebase regenerates docs and mocks, and runs contract suites in CI so QA can validate immediately.
- A backend change causes a response field to differ in production; Routebase’s drift monitor replays live responses against the spec and shows exactly which field diverged.
- Frontend and backend teams build in parallel: frontend points to the generated mock server while QA runs the same contract suites, reducing mismatches between environments.
Who is it for?
Routebase is built for API teams that maintain multiple artifacts (docs, mocks, tests, monitoring) and need them to stay aligned to prevent drift. It’s especially useful for developers running API CI pipelines and for teams using agent workflows via MCP.
