Test Your Website on Virtual Browsers
Online Without Setting Up Machines

Testsigma′s virtual browser cloud gives you every major browser, version and operating system in one place. That means you can check how your site works and looks for every visitor before you release.

Test on Chrome, Firefox, Safari, Edge and More

Test on Chrome, Firefox, Safari, Edge and More

Open your site on Chrome, Firefox, Safari, Edge, Internet Explorer and Opera across different versions and operating systems. Write a test once in plain English, or record it, and it runs on every browser you pick.

Run Cross-Browser Tests Online

Run Cross-Browser Tests Online

Run the same test on many virtual browsers at once to find the places your site breaks. Scripts that fail only in one browser, layouts that shift and forms that won't submit show up in a single report.

Catch Visual Bugs With Built-In Visual Testing

Catch Visual Bugs With Built-In Visual Testing

Testsigma takes screenshots of your pages on each browser and compares them with a baseline image. It flags visual changes such as overlapping text, missing buttons and broken layouts, so you don't have to check every page by eye.

Test User Journeys Across Desktop and Mobile

Test User Journeys Across Desktop and Mobile

See how your web application works, end to end, for users who switch between desktop web and mobile web.

One Platform for Web, Mobile,
Desktop and API Testing

The tests you build on the virtual browser also run on real mobile devices,
desktop apps and APIs, all from one place.

Run Cross-Browser Tests From Your CI/CD Pipeline

Start browser tests from Jenkins, Azure DevOps, GitHub or Bamboo on every build, and log failed steps with screenshots in Jira. Browser issues get caught while the change is still fresh, not after release.

Virtual Browser Online FAQs

What is a virtual browser?

A virtual browser is a web browser that runs on a remote server instead of your own computer. You open it in a browser tab and use it like a normal browser, but the browser itself, its version and its operating system all live in the cloud. Testers use virtual browsers to check how a website works on browsers and systems they don't have installed.

How does a virtual browser online work?

You choose a browser, a version and an operating system, and Testsigma starts that browser on a cloud machine. You see the screen in your own browser tab, and your clicks and typing are sent to the remote browser. When you finish, the session closes and nothing stays on your computer.

Is there a free virtual browser online?

Yes. Some free virtual browsers let you open a website in a remote browser for a short session. They usually limit session time, offer only a few browsers and can't run automated tests. Testsigma is built for teams that test websites on every release. You get 800+ browser and OS combinations, plain English tests you can rerun on every build, and visual testing. You can start with a free trial and then choose a plan priced for your team.

Can I use a virtual browser online without downloading anything?

Yes. The virtual browser runs in the cloud and shows up in your regular browser tab. You don't install browsers, virtual machines or plugins on your computer.

Which browsers can I test on?

You can test on Chrome, Firefox, Safari, Edge, Internet Explorer and Opera, across different versions, on Windows and macOS. Testsigma offers 800+ browser and OS combinations in total.

Why do testers use a virtual browser online?

Keeping a separate machine for every browser and operating system takes a lot of time and money. A virtual browser online lets testers switch between browsers in seconds, run the same test on all of them at once, and find compatibility issues before customers do.

What is the difference between a virtual browser and a real browser on a device?

A virtual browser runs the real browser software on a cloud machine, so pages render the way they do for your visitors. It's fast to set up and easy to scale. Performance on a specific phone or laptop can still differ, so use real devices for performance checks and the final check before release. Testsigma offers both.

Can I test mobile websites on a virtual browser?

Yes. You can test your mobile site on mobile browsers in the Testsigma cloud, including 2,000+ real Android and iOS devices. You can also test journeys that move between desktop and mobile.

Can I automate cross-browser tests on a virtual browser?

Yes. In Testsigma, you write or record tests in plain English, and they run automatically on every browser you select, in parallel. You can trigger them from tools like Jenkins or Azure DevOps on every build.

Can I use Testsigma's virtual browser to browse privately or unblock websites?

No. Testsigma's virtual browser is made for testing websites and web apps, not for private browsing or getting around network restrictions.
