Autonomous AI QA agents that verify your web and mobile app on every pull request
Describe a journey or rule in chat and the agent turns it into durable test cases that survive refactors and redesigns.
Every pull request gets a dynamic exploratory pass with preview environments, failure breakdowns, screenshots, console and network logs.
Agents target real browsers and native iOS and Android apps, so coverage reaches beyond the web front end.
Findings flow into Jira and Linear, and agents can be queried over MCP by other coding agents.

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.
