| Description | CoTester by TestGrid is an AI software testing agent that learns your product context, turns specs or JIRA stories into full test logic, and executes across real browsers and mobile devices with human-in-the-loop approval at critical checkpoints. It's built for QA and DevOps teams at enterprise scale who want to cut scripting and maintenance effort without giving up control, offering scriptless, record-and-play, and code modes. Its main differentiator is the AgentRx self-heal engine paired with a multi-modal Vision Language Model that interprets app screens like a human tester to adapt tests to major UI changes on the fly. | Replit is the collaborative browser-based IDE used by 30 million+ developers. From learning to code to building production apps with AI assistance from Ghostwriter, Replit makes software creation accessible to everyone. |
