SlimerJS
SlimerJS
SlimerJS is a free, open source scriptable browser for web developers, allowing interaction with web pages through external JavaScript scripts. It enables tasks such as opening web pages, clicking links, and modifying content, making it useful for functional tests, page automation, network monitoring, screen capture, and web scraping. Unlike PhantomJS, SlimerJS runs on top of Gecko, the browser engine of Mozilla Firefox, instead of WebKit, and can operate in both headless and non-headless modes. APIs of SlimerJS are similar to the APIs of PhantomJS but there are a few differences in their behavior. However, most of the scripts for PhantomJS run perfectly well with SlimerJS right now.Starting Price: Free -

WebPositive
WebPositive
WebPositive, or Web+ for short, is Haiku's native web browser. One part of its name is a tip of the hat to BeOS' simple NetPositive, the other points to its modern foundation: the WebKit. This open source HTML rendering library is at the heart of other mainstream browsers as well, like Safari of Mac OS X and Google's Chrome. By using the ever evolving WebKit, Web+ will be able to keep up with new web technologies. WebPositive's interface is pretty straight forward: Under a menu bar is another bar with buttons to navigate to the previous and next sites in your browsing history, to stop the loading of a page and (optionally) a button to jump to your starting page. At the bottom of the window is a status bar, showing the URL of the site being loaded or of the link the mouse pointer is hovering over. While a page is being loaded, a progress bar appears to the right.Starting Price: Free -

surf
suckless.org
surf is a simple web browser based on WebKit2/GTK+. It is able to display websites and follow links. It supports the XEmbed protocol which makes it possible to embed it in another application. Furthermore, one can point surf to another URI by setting its properties. You can navigate by clicking on links on the displayed page. Hit Ctrl-g to enter a new URL. Compile your own webkit or expect hell. The packaging of webkit is purely insane. Surf uses upstream stable webkit2gtk by default, but the previous version based on webkit1gtk is still available as a branch. surf is actively developed. You can browse its source code repository or get a copy with the simple commands. Adblocking is a non-trivial task, but there are trivial solutions. The gethostszero file can of course be reused to create the /etc/hosts file. A cronjob can be used to update the file and run hosts-gen again.Starting Price: Free -

weinre
Apache Software Foundation
weinre is WEb INspector REmote. Pronounced like the word "winery". Or maybe like the word "weiner". weinre is a debugger for web pages, like FireBug (for Firefox) and web inspector (for WebKit-based browsers), except it's designed to work remotely, and in particular, to allow you to debug web pages on a mobile device such as a phone. weinre was built in an age when there were no remote debuggers available for mobile devices. Since then, some platforms are starting to provide remote debugger capabilities, as part of their platform toolset. weinre reuses the user interface code from the web inspector project at WebKit, so if you've used Safari's web inspector or Chrome's Developer Tools, weinre will be very familiar. In normal usage, you will be running the client application in a browser on your desktop/laptop, and running a target web page on your mobile device. weinre does not make use of any 'native' code in the browser, it's all plain old boring JavaScript. -

Playwright
Playwright
Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met. Configure test retry strategy, capture execution trace, videos, screenshots to eliminate flakes. Browsers run web content belonging to different origins in different processes. Playwright is aligned with the modern browsers architecture and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.Starting Price: Free -

While switching to the WebKit 2 API means a vastly improved security situation, not all distributions of Linux package the most up-to-date version of WebKitGTK+, and several package very outdated versions that have many known vulnerabilities. As of September 2019, Arch, Debian, Fedora, Gentoo, and Ubuntu all have the latest version of WebKitGTK+, but OpenSUSE ships an outdated and vulnerable version in their stable channel. If you use Luakit for browsing, it is your responsibility to ensure that your distribution packages an up-to-date version of WebKitGTK+!Starting Price: Free -

Orion Browser
Built on WebKit, Orion gives you a fast, smooth and lightweight browsing experience, without holding your device’s battery hostage. Orion has no built-in telemetry, so it can never “phone home” and risk exposing your data. Orion is truly and verifiably a privacy-respecting browser, unlike those that offer only an illusion of privacy. Orion approaches the problem with the philosophy of "no fingerprinter running, no fingerprinting possible". The reason is that it is literally impossible to prevent fingerprinting from a sophisticated fingerprinter if one is ever allowed to run. The only efficient protection against fingerprinting is what Orion is doing - preventing the fingerprinter from running in the first place. Orion is the only browser on the market that comes with full first-party and third-party ad and tracking script blocker, built-in by default, making sure invasive fingerprinters never run on the page. -
