AI-Powered Cross-Browser Testing: How Rihario Tests Chrome, Firefox, Safari in Parallel

Most developers test on Chrome and cross their fingers for Safari. Rihario changes that by running your tests on all major engines simultaneously.

🎯 Key Takeaways

  • The "One Engine" trap: Chrome works ≠ Safari works. CSS and JS behave differently.
  • Rihario runs Chromium, WebKit, and Firefox tests in parallel.
  • AI detects browser-specific regressions automatically.
  • 100% coverage in the time it takes to run one test.

The "One Engine" Trap

Building on Chrome doesn't mean it works on WebKit (Safari). CSS grid inconsistencies, flexbox behavior, and date parsing often break on iOS devices. Manual testing is too slow.

Parallel AI Execution

When you paste your URL into Rihario, we spin up isolated containers for:

  • Chromium (Chrome, Edge, Brave)
  • WebKit (Safari, iOS)
  • Firefox Gecko

Our AI agent navigates your site in all three environments at the exact same time. If a button is unclickable in Safari but works in Chrome, the AI detects the discrepancy and flags it as a "Cross-Browser Regression."

Result: You get 100% coverage in the time it takes to run one test.
