Show HN: Argus, agentic QA for teams whose coding agents move faster than QA

Argus is a visual UI testing agent that autonomously explores web pages in a Playwright browser and produces structured reports with screenshots and timelines, eliminating the need for test scripts or selector maintenance. It processes a test description through six stages—validation, comprehension, exploration, strategy, execution, and critique—using JSON contracts and a Go-based semantic browser interface, and can verify complex flows such as navigating Y Combinator’s startup directory, evaluating actions, search results, filters, and responsive layouts.
