Treegress

Treegress

Treegress is an autonomous AI QA platform that generates and runs full end-to-end web tests from a website URL with no coding, prompts, visual baselines, or step recordings required for self-explanatory features. It scans the site, builds a testable website map, automatically creates test cases for approval, and executes them without environment setup or scripting. Teams can review and edit test data, assertions, and expected results, organize cases into test cycles, and monitor execution across releases. When a test fails, Treegress provides video replay, console logs, network logs, and shareable links so engineers can quickly understand and fix the issue. Its semantic DOM and CSS analysis interprets the live structure, styles, and layout of a web app, while a multi-agent architecture handles flow discovery, validation, and adaptation in parallel.
