Visual Regression Testing Built for AI Coding Agents
Give Claude Code, Cursor, OpenAI Codex, and Gemini CLI eyes to see visual diffs. Trigger cloud screenshot runs, evaluate AI layout summaries, and resolve regressions autonomously.
The Agent-Native Advantage
Traditional visual testing requires human reviewers to spot pixel diffs. RegressionBot translates visual changes into structured JSON summaries agents can read and act on directly.
Streamable HTTP MCP
No local browser setup or fragile binary downloads. Connect your agent straight to our hosted MCP gateway using standard Bearer authorization.
AI Vision Summaries
Our vision models analyze visual diff crops and return structured English descriptions so agents know exactly which CSS or component props broke alignment.
Autonomous Remediation
Agents don't just flag bugs—they inspect the diff summary, edit your code, verify the fix with a follow-up job, and promote new baselines when changes are intentional.
How Agents Connect via MCP
Add RegressionBot to your favorite agentic tool in seconds:
# Claude Code CLI claude mcp add --transport http regressionbot https://mcp.regressionbot.com/ --header "Authorization: Bearer YOUR_API_KEY" # Cursor MCP Settings URL: https://mcp.regressionbot.com/ Header: Authorization = Bearer YOUR_API_KEY
Stop squinting at red pixels.
When a layout changes, RegressionBot doesn't just throw a broken test and a red box at you. It uses vision models to understand the DOM and explain exactly what changed—and whether it matches your intent.
