Test REST APIs locally on Mac with an AI companion that writes your integration code
Run API requests inside a native Mac app without creating an account, with all operations performed on your machine.
Generate data models, OpenAPI specifications, and integration code from your API responses to speed up development.
The tool is optimised for REST APIs, so requests return results in under a second without protocol overhead.
Organise, import, export, and share API requests, with Postman import so existing collections come across easily.
Write code with precision, hand bigger jobs to agents, and keep working from anywhere
Agents open the repository, form a plan, edit multiple files and explain the changes so you can review each diff before accepting it. You can also run several agents in parallel to push a backlog forward.
Point the editor at Anthropic, OpenAI, Google, Microsoft or open-weight models, or bring your own key. Pick the Copilot, Claude or Codex harness that matches how you like to work.
JavaScript, TypeScript, HTML and CSS work out of the box, and Marketplace extensions add IntelliSense, linting, refactoring and debuggers for Python, Java, C++, Go, Rust and more.
Integrated terminal, source control, debugger, testing, Jupyter notebooks, an integrated browser and Dev Containers all live in one window, so you stay close to the code.
