Selenium is a toolset for automating web browsers that uses the best methods available to remotely control browser instances and simulate a user's interaction with the browser. It enables users to mimic typical end-user actions, such as typing text into forms, choosing options from drop-down menus, checking boxes, and clicking links in documents. Additionally, it offers a wide range of other controls, including mouse movement, arbitrary JavaScript execution, and much more.
Although Selenium HQ is generally used for front-end website testing, it is also a browser user agent library. The interfaces are universal in their use, which enables composition with other libraries to serve your purpose.
The source code for Selenium is accessible under the Apache 2.0 license. The project is made possible by volunteers who have kindly committed hundreds of hours to the development and maintenance of the code.

Reviews from Real Users
Selenium HQ stands out among its competitors for a number of reasons. Two major ones are its driver interface and its speed. PeerSpot users take note of the advantages of these features in their reviews:
Avijit B., an automation tester at a tech services company, writes of the solution, “The driver interface is really useful. When we implement the Selenium driver interface, we can easily navigate through all of the pages and sections of an app, including performing things like clicking, putting through SendKeys, scrolling down, tagging, and all the other actions we need to test for in an application.”
Another PeerSpot reviewer, a software engineer at a financial services firm, notes, “Selenium is the fastest tool compared to other competitors. It can run on any language, like Java, Python, C++, and .NET. So we can test any application on Selenium, whether it's mobile or desktop."
Selenium HQ was previously known as SeleniumHQ.

| Author info | Rating | Review Summary |
|---|---|---|
| Sr Manager consultant - Digital assurance Services at adrosonic | 4.0 | We use Selenium HQ for automation in testing, integrated with Azure DevOps and third-party tools. It simplifies website automation with its new features, though improvements are needed in reporting and updates. We switched from QTP and Coded UI to leverage its open-source benefits. |
| DevOps Lead at Illumifin India LLP | 4.5 | I use Selenium HQ for automating software tests on Microsoft and Java applications, integrating them into our pipeline. Its multi-browser support saves significant testing time. However, I wish it supported more diverse data sources beyond Excel. |
| Senior Quality Engineer Data at Epsilon | 3.5 | I’ve used Selenium HQ for over six years due to its effective UI testing, parallel execution, and grid handling features, though I find some areas lacking compared to Playwright, which is why I rate it 7 out of 10. |
| Senior Quality Assurance Automation Engineer at KUDO | 4.0 | I appreciate Selenium HQ for its ability to automate front-end tasks with ease and support from a global community. It's open-source, integrates with any programming language, and has straightforward documentation, though it could improve browser communication. |
| Project Manager at LTIMindtree | 4.0 | I primarily use Selenium HQ for testing applications with Java scripts on various browsers, benefiting from its compatibility and automation features. However, its documentation lacks real-time examples, and certain complex applications remain challenging to automate. |
| Product Manager at BEYS | 4.5 | I use Selenium for test automation in both personal and professional projects, notably for its user-friendly Chrome and Firefox plugins. However, documentation needs improvement for better integration with other frameworks, and easier collaboration tools would enhance the workflow. |
| Automation Specialist at Freelance | 4.0 | We utilize Selenium HQ for automating web-based tests. The platform's core features, including web driving and parallel execution, are valuable, though an auto-healing feature for script failures would be beneficial. Automation saves significant time and costs. |
| QA Manager at Next Solutions | 4.0 | I primarily use Selenium for UI and web automation with Java, appreciating its open-source flexibility and integration capabilities. It needs improvements in user-friendliness and desktop application automation. I've also worked with Katalon, WebDriverIO, Playwright, and Myspro. |
