Who Insomnia suits
Insomnia suits developers who prefer an open-source desktop API client, multi-protocol collections, scripting, Git-connected spec design and local or hosted mocks.
Where REST Test differs
- REST Test is a browser workspace rather than a desktop-first client.
- REST Test edits normalized endpoints with dedicated forms instead of a source-spec editor.
- Insomnia offers collection automation, scripts and broader import formats.
Feature comparison
| Area | Insomnia | REST Test |
|---|---|---|
| Interface | Desktop and web API client | Browser workspace |
| Spec design | OpenAPI source editor with linting and preview | Structured operation editor |
| Requests | Collections, scripts and collection runner | Operation-linked request builder and history |
| Mocks | Cloud and self-hosted mocks | Configuration only |
Migration path
- 01Export the design document as OpenAPI JSON.
- 02Import it into a REST Test workspace.
- 03Verify normalized endpoints and schemas.
- 04Rebuild request-specific values without copying secrets.
Current REST Test limits
- REST Test cannot import an Insomnia workspace export.
- REST Test has no offline desktop mode, scripts or collection runner.
- REST Test hosted mocks require a scoped workspace mock server key.
