Requests you can diff, review and merge

Every request is a readable *.rr.json file. Your API workspace lives next to your code — reviewed in the same pull request, versioned in the same repo.

Everything a REST client should be

Built for developers who want their API workspace under version control, not in someone else's cloud.

Local-first & git-friendly

Every request is a readable *.rr.json file in a folder you choose. Commit it, diff it, review it in PRs.

Scripting & tests

Pre/post JavaScript per request with a sandboxed rr.* API — assertions, variables, request mutation, snippets.

Runner, parallel & CLI PRO

Run whole collections against CSV / JSON / TXT data files with parallel workers — in the app, or in CI with npx restruno-cli run and JUnit reports.

AI assistant & MCP PRO

Generate requests and tests with AI, and let agents edit, send and run your collections through a built-in MCP server.

Import from anywhere

Bring Postman (v2.x) and Bruno collections with folders, auth, scripts and environments, or a WSDL for SOAP. Paste a cURL, get a request.

Variables & environments

Global, environment and collection scopes with {{var}} interpolation and clear precedence rules.

Questions developers ask

The short answers before you download.

Is the free version actually usable?

Yes — unlimited collections, requests, environments, scripting, tests, imports and the console are free forever. Pro adds the collection runner (data files, parallel workers and the restruno run CLI for CI), the AI assistant and the MCP server.

Where is my data stored?

On your disk, as plain *.rr.json files in a folder you choose. There is no cloud sync, no account, and nothing leaves your machine.

Can I bring my Postman collections?

Yes — import Postman (v2.x) and Bruno collections with folders, auth, scripts and environments intact. You can also paste a cURL command to create a request.

Can I run my API tests in CI?

Yes — with RestRuno Pro, npx restruno-cli run ./my-collection runs a collection in any pipeline with the same engine as the app, parallel workers, JUnit/JSON reports and exit codes your CI understands. CLI guide →

Does RestRuno handle SOAP?

Yes — import a WSDL (1.1 or 2.0) from a file or a URL and every operation becomes a ready-to-send request with the right SOAP headers and a sample envelope. XML bodies are highlighted and beautified.

Is Pro really a one-time payment?

Yes. $20 once, use it on 2 devices, keep it forever. No subscription, no renewal. Teams can get one Enterprise key for 50 devices at $149.
