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.

Self-driving AI agent for API functional regression testing
An AI agent runs end-to-end functional regression tests at the API level and tracks API changes in real time.
Devzery analyzes your PRD or project details to generate context-rich API test cases, including edge-case scenarios for broader coverage.
AI analyses complex data structures and generates accurate, up-to-date Swagger schema definitions for your APIs.
Plug into Jira, GitHub Actions and Jenkins to trigger regression suites automatically on merges and deployments.
