Web Apps Testing
Describe a user journey once and Test Circle runs it everywhere your customers are: Chrome, Firefox, Safari and Edge, on current and legacy versions, from 4K desktops down to small phones — all in parallel, with screenshots and traces for every combination.

From a sentence to a cross-browser run
Describe a journey in plain English, watch the AI author every step, pick the browsers and screens to target, then see the run stream live across all of them.
1 · Describe the test in plain English
Pick a scenario above — or type your own prompt in the product.
2 · Test Circle AI writes the steps
3 · Choose browsers & screens
Live execution
idle1920×1080 · Chromium
True cross-browser coverage
Chromium, Gecko and WebKit engines — so Safari-only and Firefox-only bugs surface before your users find them.
Version pinning
Test against the latest release, the previous ones, or a specific version your enterprise customers are locked to.
Any resolution, any device frame
Desktop, laptop, tablet and mobile viewports with real device pixel ratios — responsive regressions caught automatically.
One test, the whole matrix
Cross-browser testing has always been a maintenance tax: separate drivers, separate grids, separate scripts that drift apart. Test Circle removes the tax entirely. You author the journey once in plain English and select the environments — the engine compiles and executes that journey natively on every browser you picked.
Runs execute in parallel on managed cloud infrastructure, so a 24-combination matrix finishes in about the time a single run used to take. Nothing to provision, no grid to keep alive.
What you can cover
From the newest Chrome build to the legacy Safari version your biggest customer still runs — plus every screen your product renders on.
- Chrome, Firefox, Safari and Edge on Windows, macOS and Linux
- Latest, previous and pinned legacy browser versions
- Desktop, laptop, tablet and mobile viewports with real DPR
- Responsive layout, visual and accessibility assertions per breakpoint
- Parallel execution with per-combination screenshots, video and traces
Resilient across every environment
Selectors that drift on one browser but not another are a classic source of flaky suites. Because Test Circle locates elements semantically — by intent, text, role and visual fingerprint — the same step resolves correctly on every engine, and self-healing keeps the whole matrix green when the UI changes.
Wire the matrix into your CI/CD pipeline or a nightly schedule and you get a continuous, browser-wide safety net without a single line of automation code.
