DeployGuard: Pre-Merge Visual QA

The Problem

Teams deploy broken UI or broken user flows because manual QA takes too long, and traditional end-to-end tests (like Playwright) are incredibly brittle and time-consuming to maintain.

The Solution

DeployGuard listens for Vercel preview deployment webhooks. It spins up a headless browser, uses an AI agent to dynamically explore the core user flows of the application based on the PR description, and takes visual snapshots. It then comments directly on the GitHub PR with a pass/fail matrix and screenshots of what changed, blocking the merge if critical flows fail.
