AI UI testing that actually understands your UI
UIProof screenshots your site after every deploy, diffs the captures pixel-by-pixel, then uses AI to classify every change. Catch regressions before your users do — without writing a single test.
Built for teams that ship fast
Whether you're running AI coding agents, managing agency clients, or shipping multiple times a day — UIProof is the visual safety net you always wanted.
How AI UI testing works
Five steps from zero to automated visual QA — no test code required.
Add your site
Enter your URL and define the routes to monitor. No code changes required.
Capture a baseline
UIProof screenshots every route across desktop, tablet, and mobile viewports.
Deploy your changes
Push your code. Trigger a new capture manually or via webhook after deploy.
AI reviews the diff
UIProof compares captures pixel-by-pixel. The AI review layer classifies changes: cosmetic, regression, or intentional.
Get alerted on regressions
Email and webhook alerts fire on regressions only — so you're not buried in noise from intentional updates.
Everything in one tool
Screenshot capture, pixel diff, AI classification, UX scoring, alerts — fully integrated.
AI coding agents ship fast. UIProof reviews the result.
Codex, Claude Code, Cursor — they're changing how software gets built. But AI agents don't see what they break. UIProof gives you back the visual gate: every deploy gets reviewed by AI that looks at your UI the way a human would, flags regressions, and tells you exactly what changed.
Frequently asked questions
What makes UIProof different from other UI testing tools?
Most visual testing tools stop at pixel diffs. UIProof adds an AI review layer that classifies changes semantically — distinguishing an intentional redesign from a broken component or layout regression. It also includes persona-based UX scoring: the AI adopts your target customer's perspective and flags conversion friction, trust gaps, and clarity issues.
Do I need to write any test code?
No. UIProof works against any live URL. You define the routes to monitor and UIProof handles the rest — screenshots, diffs, and AI review are fully automated. No Selenium, no Playwright setup, no test scripts.
How does the AI classify visual changes?
UIProof sends the pixel diff and both captures to a vision AI model. It returns a classification (cosmetic / regression / intentional) with a severity score and plain-English explanation. You see exactly what changed and whether it matters.
Can I use UIProof with AI coding agents like Codex or Claude Code?
Yes — this is one of UIProof's core use cases. AI coding agents ship fast, which is great, but they can introduce subtle visual regressions. UIProof is the visual gate that runs after each agent-driven deploy so you catch layout shifts and style drift before users do.
What viewports does UIProof test?
UIProof captures desktop (1440px), tablet (768px), and mobile (390px) by default. Every route is tested across all three on every capture run.
Does UIProof integrate with my CI/CD pipeline?
Yes. UIProof exposes a public REST API so you can trigger capture runs from GitHub Actions, Vercel deploy hooks, or any webhook-based CI/CD pipeline. API keys are managed in your dashboard under Settings → API Keys.
