Best-in-class automated issue detection

Explore examples of our ever-expanding rules that detect critical issues

Screen reader focus order for elements

Every interactive element must be reachable via a screen reader's linear navigation, ensuring all actionable components are available when navigating sequentially

Use the correct input type for all data fields

Improve usability by setting appropriate input types—like email, number, or date. Our rule detects inaccurate types to ensure a better experience for assistive tech users

Detect usage of images to display text

Spectra™ detects images of text so they can be rendered as real text. This improves accessibility for screen readers and lets users customize font size, color, and style.

Get AI-driven, in-depth complex issue detection

A11y Issue detection agent can detect issues with human-like intelligence including the examples below

Check meaningful reading order with AI

Spectra™ ensures the focus order of interactive elements matches the visual and logical sequence, verifying that screen readers follow a natural reading flow for all users.

Write meaningful alt-text for all images

Ensure accessibility labels for images convey purpose and context. AI provides remediation guidance by suggesting contextual meaningful alternatives.

Use meaningful labels for all interactive elements

Ensure screen readers clearly announce all interactive elements. Our AI detects and fixes vague labels, providing meaningful descriptions for buttons, links, and custom views.

Fix issues with smart guidance & code-snippets

Spectra’s A11y agent auto-fixes WCAG issues using your app’s context and human-like intelligence. Using AI you can:

Add correct input types for form fields

AI suggests semantic input types (e.g., email, password, phone) so assistive tech can identify field purposes accurately.

Optimize responsive containers for reflow

AI detects layout issues when zooming or resizing and recommends container fixes to maintain readability and usability.

Enable text resizing without loss of content

AI recommendations ensure your app supports scalable font sizes, allowing users to magnify text without breaking layouts.

BrowserStack supports WCAG Accessibility testing for mobile apps.

We can automate our testing and reporting for any number of executions. The visual scanner helps test our app UI, and after test execution, we get a detailed report highlighting the impact of each accessibility issue.

BrowserStack is one of the best tools for Mobile Accessibility Testing. No other tool in the market allows screen reader features in a virtual mobile. It has Screen Reader option for Android and iOS for both mobile and tablets.

BrowserStack gets the work done for Accessibility. We use BrowserStack for some regression testing on the company.
