    What is cross-browser testing?

    Cross-browser testing is crucial for ensuring a website performs well across all browsers, devices, and operating systems.

    Cross-browser testing tools make this process easier. And you can fit this during the final stages of any website development project.

    We've simplified your search by comparing 12 of the best cross-browser testing tools.

    Let’s dive right in.

    12 Best Cross-Browser Testing Tools

    Here are 12 of the best cross-browser testing tools, reviewed for their features, use cases, and pricing.

    1. Marker.io

    Report bugs and send feedback straight into your project management tool—from any browser.

    Marker.io enhances your QA testing by automatically capturing environment details with each bug report, speeding up cross-browser testing.

    Let’s look at a few other Marker.io features.

    2-way PM integrations

    Marker.io boasts comprehensive integrations with popular PM tools like Jira, Trello, and ClickUp.

    This allows testers or clients to easily report issues with a single click through a feedback widget.

    Feedback then goes straight into your PM software. No more jumping back and forth between multiple tools or searching for feedback in emails or Slack.

    Developers won’t need to get used to another piece of software in their tech stack.

    Issues are reported via Marker.io, developers action them in their PM tool, and updates are automatically sent to the reporter.

    No more wasted time updating issue status for clients and testers!

    Check it out in action:

    Example of Marker.io status sync, marking an issue as Resolved in Marker.io as soon as it is moved to the Done column in the project management tool

    Visual feedback with annotations

    Example annotations in Marker.io

    Marker.io operates as a simple, yet powerful widget on live or staging sites. It can be easily integrated with a line of code or a WordPress plugin.

    Because of this, reporting issues during cross-browser testing is straightforward for everyone involved.

    Let’s say you’ve got a team testing a new site on a range of devices and web browsers.

    It works well on 90% of platforms, but some browser/OS combinations experience loading issues.

    Your team needs to identify which pages, browsers, and operating systems are underperforming.

    Thankfully, sending a report with Marker.io is then a simple, 3-steps process:

    1. Find an issue, click the button
    2. Fill out the report and input details
    3. Click on “Create issue”—done!

    Marker.io simplifies website debugging across different browsers with extensive visual reporting options.

    • Automatic screenshots
    • Annotations
    • Notes
    • Even emojis, and loads more!

    Detailed bug reports

    When you try to get feedback from your clients, it’s usually from people who aren’t tech-savvy.

    Most users don’t know what developers need to fix a bug, especially if the issue is only occurring on a few browser and OS combinations.

    To address this, Marker.io automatically captures the information your devs need to retrace the tester’s steps—with every report:

    • Reporter name
    • Source URL
    • Console logs
    • Environment info
    • Session replay
    • Any custom metadata

    See the issue with session replay

    Example of Marker.io session replay attached to an issue page

    As a developer, your first step upon receiving a bug report is to recreate the issue's environment.

    You need to perform the same actions as the tester on the same device, browser, and operating system.

    Most cross-browser testing platforms allow easy recreation of issues in virtual cloud environments.

    Marker.io's bug reports provide all necessary technical data, including environment and console logs, along with visual notes from testers.

    But even with all the technical data in the report—sometimes, you still need more information.

    And for project managers, it’s not always possible to arrange a quick call with testers. If only you could see exactly what happened in the environment when the issue occured...

    Well—Marker.io's toolkit includes session replay for that reason.

    Straight from your PM tool, simply click the “Watch replay” link.

    You’ll then be able to watch the last 30 seconds (or more) before the report is submitted.

    Check out session replay in action:

    Finally, Marker.io was not designed just for cross-browser testing.

    You can use it for internal QA as well as throughout your user acceptance testing process.

    Frequently Asked Questions

    What is cross-browser testing?

    Websites need to work exactly the same on any browser, device, and OS combination.

    In other words, functional websites need to be environment-agnostic.

    Cross-browser testing is a critical aspect of website development, ensuring functionality across:

    • Various browsers and operating systems, particularly popular ones like Chrome, Firefox, Edge, Safari, macOS, iOS, Windows, and Android.
    • Different devices, ensuring websites perform well on smartphones, tablets, laptops, and desktops.
    • Assistive technologies, making websites accessible to those with visual impairments or other disabilities, crucial for user experience and compliance.

    What are the advantages of cross-browser testing?

    Browser providers all adhere to web standards, also known as Open Web Standards or W3C standards.

    However, standards interpretation and implementation vary, and the technology behind real browsers and operating systems continuously evolves.

    It is up to web developers to ensure that websites function the same way regardless of the platform a user is on.

    Cross-browser testing identifies and resolves browser-specific issues before a website goes live.

    Without it, agencies risk losing a portion of their audience if the site fails on certain devices or browsers.

    Cross-browser testing prevents this from happening.

    How does cross browser testing compare to other types of testing?

    Cross browser testing is typically conducted by in-house or outsourced software and quality assurance engineers.

    It can be done by crowd-sourced user or beta testers, depending on how extensive your testing needs to be.

    However, it doesn’t have to involve real or beta users.

    It’s a type of internal testing (in some cases, even automated) before a website is launched, or before it’s given to a client or beta users for testing.

    Cross-browser testing efficiently ensures a website functions properly in real-time across numerous browsers, devices, and locations.

    You can achieve this through manual testing, DevOps tools, or automation tools.
