Design, test, mock and document APIs from one OpenAPI spec
Best for you if:

- • You want docs, mocks and contract tests are generated from the same OpenAPI description, so they cannot drift apart
- • You want native MCP server covering the full feature set, so agents work the same workspace as the team under the same role permissions
Insomnia
API client for REST and GraphQL
Best for you if:
- • You want supports 7+ API protocols in a single tool, no need for separate clients
- • You want free tier includes unlimited local projects, collection runs, and environments
