Brave is a free and open-source web browser developed by Brave Software, Inc. based on the Chromium web browser. The browser blocks ads and website trackers. The company has proposed adopting a Get paid to surf business model in a future version of the browser.

Brave created a new “blockchain-based advertising model that reforms the current system with privacy by design and 70 percent revenue share to users in the form of Basic Attention Tokens (BAT)”. Users may opt-in to view ads to earn BAT which they may convert into digital assets and fiat currencies, or use to support their favorite publishers, content creators, and companies.

According to Brave Software, “ad matching happens directly” on user devices which means that data is not sent to anyone.

Basilisk is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (a fork of Gecko) and builds on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla code base without Servo or Rust.

Basilisk as an application is primarily a vessel for development of the XUL platform it builds upon, and additionally a potential replacement for Firefox to retain the use of Firefox Extensions.

Basilisk is development software. This means that it should be considered more or less “beta” at all times; it may have some bugs and is provided as-is, with potential defects. Like any other Free Software community project, it comes without any warranty or promise of fitness for any particular purpose. That being said: of course we will do our best to provide an as stable and secure browser as possible with every official release of Basilisk.

Microsoft Edge is a web browser developed by Microsoft. It was first released for Windows 10 and Xbox One in 2015, then for Android and iOS in 2017, and for macOS in 2019.

Edge includes integration with Cortana and has extensions hosted on the Microsoft Store. Unlike Internet Explorer, Edge does not support the legacy ActiveX and BHO technologies.

Originally built with Microsoft’s own EdgeHTML and Chakra engines, in 2019 Edge was rebuilt as a Chromium-based browser, using the Blink and V8 engines. As part of this change (codenamed Anaheim), Microsoft has made the preview builds of Chromium-based Edge available on Windows 7, 8, 8.1 and macOS, in addition to Windows 10. Microsoft released the first Chromium-based Edge version on January 15, 2020.

Chromium是一个由Google主导开发的网页浏览器，以BSD许可证等多重自由版权发行并开放源代码。Chromium的开发可能早自2006年即开始，设计思想基于简单、高速、稳定、安全等理念，在架构上使用了Apple发展出来的WebKit排版引擎、Safari的部份源代码与Firefox的成果，并采用Google独家开发出的V8引擎以提升解译JavaScript的效率，而且设计了“沙盒”、“黑名单”、“无痕浏览”等功能来实现稳定与安全的网页浏览环境。

Chromium是Google为发展自家的浏览器Google Chrome（以下简称Chrome）而开启的计划，所以Chromium相当于Chrome的工程版或称实验版（尽管Chrome自身也有β 版阶段），新功能会率先在Chromium上实现，待验证后才会应用在Chrome上，故Chrome的功能会相对落后但较稳定。
