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.

Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
