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.

🔁

Data-driven runner PRO

Run collections against CSV / JSON / TXT data files, one pass per row, with pass/fail results per request.

🤖

AI assistant & MCP PRO

Generate requests and tests with AI, and expose your collections to agents through a built-in MCP server.

📦

Import from anywhere

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

🌐

Variables & environments

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

// pricing

Simple, one-time pricing

The core client is free forever. Pro unlocks the power features — pay once, no subscription.
