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.

Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
Delivers exceptional UI generation and full-stack app creation, but focuses less on traditional multi-language code editing than Replit.
