Cross-Browser Testing That Catches What Emulators Miss

A site that works perfectly in Chrome can break completely in Safari. We test across every major browser on real devices -- catching rendering inconsistencies, interaction failures, and performance issues before your visitors encounter them.

What's Included

Everything you get with our Cross-Browser Testing

Multi-Browser Test Suite

Systematic testing across Chrome, Safari, Firefox, and Edge on current and previous versions, covering the browser combinations that represent 95%+ of your traffic

Real Device Testing

Testing on actual iOS devices (iPhone, iPad), Android phones and tablets, and desktop platforms -- not emulators -- to catch hardware-specific rendering and interaction issues

Bug Report & Fix Documentation

Detailed bug reports with screenshots, browser versions, and recommended fixes prioritized by traffic impact and severity

Our Cross-Browser Testing Process

Traffic Analysis & Browser Matrix

We analyze your analytics to identify exactly which browser-device combinations your visitors use. This data creates a prioritized testing matrix that focuses effort on the combinations that matter most to your business.

Systematic Browser Testing

We test every page and interaction across the prioritized browser matrix on real devices. Each test covers layout rendering, interactive elements, form submissions, animations, and performance metrics specific to each browser.

Bug Documentation & Prioritization

We document every inconsistency with screenshots, browser details, and traffic impact data. Issues are categorized by severity (critical, major, minor, cosmetic) and prioritized by the percentage of traffic affected.

Fix Implementation & Verification

We implement fixes for all critical and major issues, verify them across the full browser matrix, and establish automated visual regression tests that catch new inconsistencies as browsers update and your site changes.

Key Benefits

Consistent Experience for All Visitors

When every visitor sees the same polished experience regardless of their browser, your brand credibility is protected. A single browser-specific bug can affect 15-30% of your traffic depending on the browser. Cross-browser testing ensures no segment of your audience encounters a broken experience.

Catch Issues Before Visitors Report Them

Most visitors who encounter a browser bug do not report it -- they leave. Proactive cross-browser testing catches these issues before they cost you conversions. We test before launch and after every significant update to maintain consistency as browsers release new versions.

Prioritized Fixes Based on Traffic Impact

Not all browser bugs are equally important. We prioritize fixes based on which browsers your visitors actually use, the severity of each issue, and its impact on conversion. A minor visual inconsistency in a 2% browser gets lower priority than a form failure in a 25% browser.

Frequently Asked Questions

Which browsers do you test?

We test Chrome, Safari, Firefox, and Edge on their current and previous major versions. On mobile, we test Safari on iOS and Chrome on Android. We also test any additional browsers that represent significant traffic in your analytics. Our standard testing covers 95%+ of typical web traffic.

Why test on real devices instead of emulators?

Emulators simulate browser rendering but miss hardware-specific issues: touch interaction bugs, scroll performance problems, font rendering differences, and animation jank that only appear on actual devices. Real device testing is more expensive and time-consuming but catches issues that emulators consistently miss.

How often should cross-browser testing be done?

At minimum, test before every major site launch or redesign. Ideally, run automated visual regression tests on every deployment and full manual testing quarterly. Major browser updates (like new Safari or Chrome versions) should trigger targeted retesting of known problem areas.

What about older browsers like Internet Explorer?

We test browsers that represent meaningful traffic for your site. If your analytics show IE traffic, we include it. For most sites, IE support is no longer necessary. We recommend graceful degradation for old browsers: the site should be usable but does not need to look identical to modern browser rendering.
