Now Live with LambdaTest Web Scanner: Schedule Visual & Accessibility Scans At Scale

Shipping fast breaks UI in small ways that users feel first: shifted buttons, clipped text, missed alt tags, contrast failures. At scale, catching these across pages, viewports, and releases is tedious and easy to miss especially behind logins or on staging.

Why use a Web Scanner?

Manual testing of large-scale web applications for layout shifts, broken UI elements, or WCAG non-compliance is time-consuming, error-prone, and simply doesn’t scale. Here’s how Web Scanner transforms your testing approach:

• Eliminate Manual Bottlenecks: Say goodbye to hours spent clicking through pages and comparing screenshots manually. Web Scanner automates the entire process, freeing your team to focus on strategic testing initiatives.
• Catch Issues Before Users Do: With scheduled scans and instant alerts, you’ll identify visual regressions and accessibility violations before they impact your users’ experience.
• Ensure Compliance at Scale: For organizations that need to maintain WCAG compliance across hundreds or thousands of pages, Web Scanner provides audit-ready reports that make compliance verification effortless.
• Save Time and Resources: Automate what used to take days into a process that runs in hours, with results delivered directly to your SmartUI and Accessibility Dashboards.

Visual UI Scanning

Visual scans detect pixel-based layout changes, design mismatches, missing elements, or unintended visual regressions by comparing screenshots taken at scheduled intervals.

Key Capabilities:

• Cross-Browser Validation: Test UI across Chrome, Firefox, Edge, and Safari.
• Responsive Testing: Check layouts on 8 desktop sizes and 200+ mobile viewports (Android & iOS).
• Custom Configurations: Override defaults with your own SmartUI JSON settings.
