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.
Agentic end-to-end testing that writes, runs and heals your test suite
Agents drive a real browser and live APIs like a user would, so a pass means the flow genuinely works end to end.
Each failure arrives with the failing step, screenshots, DOM snapshots, test source, root-cause hypothesis and a suggested fix.
Tests repair themselves when the UI drifts, and every passing test is kept so coverage grows with the app.
The same verifier runs from an open-source CLI, an MCP server in your IDE, a CI merge gate, or a no-code dashboard.
