    When you have to test the UI and how it behaves when certain actions are performed, you need something that can automate the browsers. This is where Selenium comes to the rescue. If you have to test APIs and not the frontend (UI), I would recommend going with other libraries that support HTTP Requests. Selenium is good only when you have no choice but to run the steps on a browser.

    Supernova is the best documentation platform on the market, having tested numerous alternatives, including the more popular zeroheight, Knapsack, etc. It's ideal for low-code solutions for brand guidelines and detailed component documentation. Their automated exporter pipelines are the icing on the cake, enabling them to pull what you see in Figma and push it directly into your codebase.

    • It supports multiple coding languages like Java, Python, Ruby, C# etc.. to choose from.
    • There is a huge community of users and can get many answers on StackOverFlow.

    Cons
    Open Source
    • Selenium is pretty user-friendly but sometimes tests tend to flake out. I'd say roughly one out of twenty tests yields a false positive.
    • Selenium software cannot read images. This is a minor negative because a free plug-in is available from alternate sources.
    • Slowness may be a minor factor with Selenium, though this is an issue with basically any testing software since waiting on a site to execute JavaScript requires the browser to wait for a particular action.

    • Difficult to sync large files (more of a Figma problem).
    • Restrictive paid tiers.
    • Redundant features.

    We love this product mainly because of its high customization abilities and the ease of use. Moreover, its free and can be learned easily through online communities and videos. The tests are more consistent and reliable as compared to Manual tests. It has enabled us to test a large number of features all in one go, which would have impossible through manual tests. The reports generated at the end of the tests are really helpful for the QA and the development teams to get a fair view of the application.

    Usability
    Open Source
    For those who are unfamiliar with coding, there is a bit of a learning curve. There is plenty of helpful documentation and resources but it can take a little time to get the software up and running. Once you get the hang of how Selenium works, and what it can do, you realize how many things you can use it for, and how many processes you can automate.

    It is occasionally buggy, but nowhere near as buggy as zeroheight.

    The Selenium app has a pretty fat community of users. For the problems we are experiencing, we are primarily receiving support from these communities. In addition, there is widespread service support. Instant support is given to the problems we experience when we need Online support. We and our team are happy to provide this support, especially before important deployment processes

    We did everything we needed to use it. Now we can execute our tests on different operational systems and browsers running few tests simultaneously. We also implemented Appium framework to execute our tests on mobile devices, such as iPhones, iPads, Android phones and tablets. We use SauceLabs for our test execution and Jenkins for continuous integration.

    At the time of adoption, there were not many other alternatives that were even close to being competitive when it comes to browser testing. As far as I know now to this day, there is still little competition to Selenium for what it does. Any other browser-based testing still utilises Selenium to interact with the browser.

    Supernova has best-in-class customer service. Our Figma library is a huge file and was unable to automatically sync with most platforms (including Supernova) - of all three platforms we tried, Supernova was the only one that actively assigned engineers to our case and offered a solution within a couple of days. They've been great partners.

    Return on Investment
    Open Source
    • There hasn’t been a downside to using it yet other than we’ve got to update the programs we create for each change.
    • This has saved us hundreds of hours of manpower by allowing our automation engineer to rapid fire tests.
    • We are able to screenshot and save entire sites before and after launch with a program the automation engineer created
    • We can compare large volumes of data against data in excel docs with a program created using Selenium

    Supernova Screenshots

    Screenshot of the home dashboard, which offers a central overview of a design system's health at a glance — token, component, asset, and doc counts alongside live data pipelines connecting Figma, Storybook, and code destinations like Style Dictionary.Screenshot of the documentation editor, with inline commenting, review requests, and version drafts — letting teams document component usage guidelines (do's/don'ts) directly alongside live examples.Screenshot of a full semantic token library with values, dark-mode variants, and ready-to-use CSS variables — keeping design and code perfectly in sync across collections.Screenshot of usage analytics for design system documentation, used for tracking page views, sessions, and engagement trends so teams can see which patterns and guidelines get used most.
