Cross-platform cross-browser compatibility testing

The Cost of Incompatibility

When applications don't work consistently across platforms and browsers, users experience broken functionality, visual glitches, and performance issues. This fragmented experience leads to frustrated users, abandoned sessions, and lost revenue. Comprehensive compatibility testing ensures every user enjoys the same quality experience regardless of their platform or browser choice.

Browser-specific rendering issues causing layout and styling problems
Platform-dependent code breaking functionality on certain devices
Performance variations across browsers impacting user satisfaction
Missing feature support in older browsers limiting accessibility
Mobile and desktop experiences being inconsistent or broken

Key Benefits of Compatibility Testing

Reach all users with a consistent, high-quality experience across platforms and browsers

Broader User Reach

Support diverse browsers and platforms to serve all your users. Don't force users to switch browsers—reach them where they are.

Consistent Performance

Ensure your application performs smoothly across all platforms. No surprises or degraded experiences on specific browsers or devices.

Higher Conversion Rates

Users who experience consistent, functional applications are more likely to convert. Broken experiences on any platform lose business.

Reduced Support Costs

Compatibility issues are major support drivers. Fixing them upfront reduces support tickets and costs significantly.

Our Compatibility Assessment Approach

Browser Compatibility Testing

Test Across All Major Browsers

We systematically test your application across all major browsers including Chrome, Firefox, Safari, and Edge in multiple versions. We identify rendering issues, JavaScript compatibility problems, and feature support gaps.

Test on current and legacy browser versions
Identify browser-specific CSS rendering issues
Detect JavaScript compatibility problems
Verify feature support (APIs, standards compliance)
Test responsive behavior on different screen sizes

Platform Compatibility Analysis

Ensure Consistent Experiences

We evaluate your code across different operating systems and devices: Windows, macOS, Linux, iOS, and Android. We identify platform-specific issues and ensure uniform functionality.

Test on Windows, macOS, Linux operating systems
Verify iOS and Android mobile compatibility
Check tablet and responsive design behavior
Identify platform-specific bugs and quirks
Assess performance across different hardware

CSS & Layout Compatibility

Visual Consistency Across Platforms

Different browsers render CSS differently. We identify layout issues, visual glitches, and styling inconsistencies that break the user experience on specific platforms.

Identify CSS browser compatibility issues
Test CSS Grid and Flexbox across browsers
Verify font rendering consistency
Check for layout shifts and visual bugs
Test print styles and media queries

JavaScript & API Compatibility

Functional Consistency Across Environments

JavaScript features and APIs vary across browsers and versions. We test for compatibility issues and provide polyfills or alternative implementations where needed.

Test JavaScript ES6+ compatibility
Verify Web API support across browsers
Identify missing polyfills and shims
Check async/await and Promise behavior
Test browser storage APIs compatibility

Compatibility Testing & Fix Roadmap

1

Define Target Browsers & Platforms

Establish which browsers, versions, and platforms your application should support based on user analytics and business requirements.

2

Comprehensive Compatibility Audit

Test your application across all target browsers and platforms to identify compatibility issues and gaps.

3

Document Issues & Impact

Create detailed report documenting all compatibility issues, affected browsers/platforms, severity level, and user impact.

4

Prioritize Issues

Prioritize compatibility issues based on affected user base, severity, and impact on functionality and conversions.

5

Develop Fix Strategies

Determine optimal fixes for each issue: polyfills, feature detection, fallbacks, or code rewrites.

6

Implement Fixes

Update code to resolve compatibility issues with minimal impact on other functionality. Add polyfills and fallbacks where needed.

7

Retest Across Platforms

Verify that fixes work correctly across all target browsers and platforms. Ensure no regressions were introduced.

8

Establish Monitoring

Set up continuous testing and monitoring to catch compatibility issues early and prevent regression in the future.
