Website and web app Testing

Cover every component, page, and browser

Applitools covers every layer of your web app, from a single component to a full cross-browser release, with Visual AI catching what a functional test alone would miss.

Test every layer

Validate a single Storybook component, a full page, or a release across hundreds of browsers, all from the same SDK.

Run fully in the cloud

Execute your entire suite in parallel in the cloud, so a full cross-browser run takes minutes instead of hours.

Debug with full context

Every run comes with video and logs, so you can see exactly what happened instead of re-running the test to find out.

What Applitools covers across your web app

Optimizely + AI Coding Agents: Give your dev team visual "eyes."

Start testing before a page even exists

Component-level checks Test a component in Storybook as it's built, so a visual bug gets caught before it ships to a real page.

Full-page coverage from the same SDK Use the same eyes.check call to validate an entire page once components come together. No separate tool required.

Run against hundreds of browsers without hundreds of machines

The Ultrafast Grid An engine that reproduces each browser's rendering in parallel instead of spinning one up for every test, so a full cross-browser run takes minutes.

Parallel execution in the cloud Your entire suite runs in parallel in the cloud, so adding more browsers doesn't add more time to your pipeline.

Test what's behind your firewall, too

Run in your existing framework SDKs integrate directly with Playwright, Cypress, Selenium, and Appium, so it's the same test you already wrote, not a new tool to learn.

Local and private app support Connect to apps behind a firewall or on a local network, so security requirements don't slow down your testing.

Know what happened without re-running the test

Full logs and video Every run comes with a video and detailed logs, so you can see exactly what the browser did instead of guessing.

Root Cause Analysis See the exact DOM and CSS change behind a diff, so a failure comes with an answer, not just a red X.

What backs up every web test

1

Auto-maintenance

Group related visual changes across browsers and resolutions and update every affected baseline in one click.

2

Dynamic content handling

Choose the AI match level that works for you to control what counts as a regression, and let Applitools automatically ignore dynamic data like timestamps, session IDs, and A/B content instead of flagging it as a failure.

3

Cross-browser and -device coverage

The Ultrafast Grid and Native Mobile Grid render the same test across every browser and device in parallel, without a local grid to maintain.

4

Deterministic Language Model

The same input always produces the same output, so a result is something you can explain and trust, not a probability.

5

Human-eye simulation

Visual AI ignores rendering noise like anti-aliasing and sub-pixel shifts, and flags only the changes a real user would notice.

6

No-code and code authoring

Write checks in plain English, record a flow, or write code directly, so the whole team can add coverage.
