Core Features
The essential tools for catching visual bugs before your users do.
Cross-Browser Testing
Test your website on Chrome and Firefox simultaneously. Catch browser-specific rendering issues, font rendering differences, and CSS quirks before they reach production. Our parallel testing approach means you get results for both browsers in a single run.
Responsive Breakpoints
6 carefully selected preset resolutions covering desktop (1920x1080, 1366x768), tablet (1024x768, 768x1024), and mobile (375x667, 414x896). Ensure your site looks pixel-perfect on every device your users might have.
Blazing Fast
Our optimized screenshot capture and comparison pipeline delivers results in seconds, not minutes. Parallel processing means testing multiple browsers and resolutions simultaneously without waiting.
GDPR Compliant
All your data is hosted in Frankfurt, Germany (EU). We built ScanU with European privacy regulations at its core. No data leaves the EU, no third-party trackers, no compromise on privacy.
Baseline Management
Your first test run automatically becomes the baseline. Accept intentional changes with a single click to update your baseline. Reject regressions to flag them for fixing. Full control over your visual testing workflow.
Smart Notifications
Get notified only when it matters. Instant email alerts for detected regressions, comprehensive summaries when test runs complete. No noise, just actionable information.
And Much More
Additional features that make ScanU the complete visual testing solution.
Side-by-Side Comparison
Compare baseline and current screenshots side by side, use the overlay slider, or view only the diff. Zoom, pan, and navigate with keyboard shortcuts.
Historical Comparison
Keep a complete history of all your test runs. Compare any two snapshots at any time. Track visual changes over your project lifetime.
Team Friendly
Built for small teams, freelancers, and agencies. Simple pricing with no per-seat fees. Everyone on your team can access the same projects.
Secure by Design
SSRF protection prevents testing of private networks. Rate limiting stops abuse. JWT authentication keeps your account secure.
Diff Threshold Control
Set a custom diff threshold per project. Reduce false positives from anti-aliasing or minor rendering differences. Find the sweet spot for your needs.
Project Organization
Organize your websites into projects. Each project has its own baseline, settings, and test history. Clean separation for multiple clients or sites.
One-Click Retesting
Run new tests with a single click. No complex configuration needed. Just hit the button and watch the magic happen.
