AI Agent Visual QA Tool (DevTools)

Give coding agents 'eyes' to verify UI work by providing visual testing and verification. Coding agents write code but can't see if layouts are broken, dropdowns clipped, or pages rendering wrong. This CLI + MCP server lets agents visually assert and fix their own frontend work. Target: AI code generation platforms.

The rise of autonomous coding agents — Cursor, Devin, GitHub Copilot Workspace — has exposed a genuine blind spot: these tools can write frontend code but have no mechanism to verify visual output, so broken layouts ship silently. No clear incumbent owns this exact niche, though Percy and Chromatic address visual regression for humans rather than agent-in-the-loop workflows. The $2k–8k/mo revenue band is realistic for a CLI/MCP tool selling to developer teams rather than enterprises, but it implies a fairly low ceiling unless it becomes embedded infrastructure for a major agent platform. The biggest risk is that Anthropic, OpenAI, or the agent platforms themselves ship native screenshot-and-verify tooling, collapsing the independent market before any meaningful distribution is built.
