Visual QA for AI Coding Agents

AI coding agents generate HTML/CSS that looks valid but breaks in real browsers. A CLI tool that gives agents 'eyes' to visually verify UI work, catch layout issues, and assert visual correctness would be critical infrastructure as AI coding becomes more common.

Agentic coding workflows—Cursor, Devin, Claude Code—are shipping HTML that passes linters but fails visually, and no one has solved the feedback loop problem at the agent layer yet. Percy and Chromatic handle human-driven visual regression testing but are built around pull request workflows, not autonomous agent loops that need synchronous visual assertions mid-task. The $2k–$10k MRR band is plausible for a CLI tool sold per seat or per agent-run to teams already paying for Cursor Business or similar, though the ceiling depends heavily on whether the major agent platforms bake something like this in natively. That platform risk is the core threat: if Anthropic or Vercel ships a native visual verification step inside their agent runtimes, the standalone tool becomes redundant fast.
