UI touch-ups would help with the user-friendliness.

Browsershots

Browsershots is a completely free, unlimited cross-browser testing tool.

Features

The tool is lightweight and straightforward.
It is open-source.
Provides the ability to test websites on various OSs, allowing you to see how the sites are displayed across different environments.
Can be used to automate the process of taking screenshots on multiple browsers and OSs, reducing the need for manual testing.
You can scale the screen size down to see how the website responds on mobile devices.
You can choose specific browsers, versions, screen resolutions, color depths, and other settings to customize the testing parameters to your needs.

Limitations

Presents static screenshots and doesn’t offer the capability to interact with the website or test functionality like form submissions, AJAX requests, or dynamic content.
Primarily focuses on capturing screenshots, which might not be sufficient for thoroughly testing complex web apps that require interaction and functionality verification.
Depending on the demand for the service, there might be delays in getting screenshots due to the queue of pending requests.
Might not support the latest browser versions or have a wide range of browser options compared to some modern cross-browser testing platforms.
Since Browsershots generates screenshots, it doesn’t provide real-time testing or instant feedback on how a website behaves.
The tool might be limited in terms of server resources, leading to slower processing times during peak usage.

Selenium

Selenium is another free tool. But it also has infrastructure/extra service costs.

Features

An open-source tool that automates web browsers.
Cross-browser testing in Selenium enables rapid, repeatable web-app testing.
Provides a single interface that lets you write test scripts in desired programming languages.
Allows developers and QA engineers to automate the testing of web apps across different browsers and platforms.
Provides access to a Cloud Selenium Grid of 3000+ desktop browsers and real mobile devices.

Limitations

Requires programming skills.
May take time to set up and configure the tool.
May not be the best choice for non-technical users or those who prefer a codeless testing approach.

To Sum Up

Free browser compatibility testing tools (or their versions) are a great way to learn. You can upgrade your skills and decide whether to continue your cooperation with a particular software. But don’t be quick to judge freemiums and trials. They may lack advanced features, not cover the latest browser versions, accurately simulate real-world performance, or be intentionally better than paid extensions.

Making the right choice is about research and intuition. For the former, we recommend G2, Clutch.co, TrustRadius, Gartner, Capterra, and SourceForge. And checking in with QA Madness’ blog wouldn’t hurt either.

Best of luck with your search.
