Chromium (web browser) in the context of "Samsung Internet"

Google Chrome is a cross-platform web browser developed by Google. It was first released in 2008 for Microsoft Windows, built with free software components from Apple WebKit and Mozilla Firefox. Versions were later released for Linux, macOS, iOS, iPadOS, and also for Android, where it is the default browser. The browser is also the main component of ChromeOS, on which it serves as the platform for web applications.

Most of Chrome's source code comes from Google's free and open-source software project known as Chromium, but Chrome is licensed as proprietary freeware. WebKit was the original rendering engine, but Google eventually forked it to create the Blink engine; all Chrome variants except iOS used Blink as of 2017.

Blink is a browser engine developed as part of the free and open-source Chromium project. Blink is by far the most-used browser engine, due to the market share dominance of Google Chrome and the fact that many other browsers are based on the Chromium code.

To create Chrome, Google initially chose to use Apple's WebKit engine. However, Google needed to make substantial changes to its code to support Chrome's novel multi-process browser architecture. Over the course of several years, the divergence from Apple's version increased, so Google decided to officially fork its version as Blink in 2013.

KHTML is a discontinued browser engine that was developed by the KDE project. It originated as the engine of the Konqueror browser in the late 1990s, but active development ceased in 2016. It was officially discontinued in 2023.

Built on the KParts framework and written in C++, KHTML had relatively good support for Web standards during its prime. Engines forked from KHTML are used by most of the browsers that are widely used today, including WebKit (Safari) and Blink (Google Chrome, Chromium, Microsoft Edge, Opera, Vivaldi, Opera GX, Opera Mini, Opera Mobile, Yandex Browser, Orion, Arc (On iOS), Epiphany, Midori, Konqueror, Otter Browser, Dooble, Epic Privacy Browser, Slimjet, Comodo Dragon, SRWare Iron, Cốc Cốc, Torch Browser, Orbitum, UC Browser, Kiwi Browser, Samsung Internet, Bromite, Blisk, Colibri Browser, Min Browser, Ungoogled Chromium, Iridium Browser, Avast Secure Browser, AVG Secure Browser and Brave).

Amazon Silk is a web browser developed by Amazon. It was launched in November 2011 for Amazon Fire and Fire Phone, and a Fire TV version was launched in November 2017. The addition of Silk to the Echo Show was announced at an Amazon event in September 2018.

The browser uses a split architecture where some of the processing is performed on Amazon's servers to improve webpage loading performance. It is based on the open source Chromium project that uses the Blink and V8 engines.

Microsoft Edge is a proprietary cross-platform web browser created by Microsoft and based on the Chromium open-source project, superseding Edge Legacy. In Windows 11, Edge is the only browser available from Microsoft. However, a bypass is available to open Internet Explorer.

First made available only for Android and iOS in 2017, in late 2018, Microsoft announced it would completely rebuild Edge as a Chromium-based browser with Blink and V8 engines, which allowed the browser to be ported from Windows 10 to macOS. The new Edge was publicly released in January 2020, and on Xbox as well as Linux in 2021. Edge was also available on Windows 7 and 8/8.1 until early 2023.

Opera is a multi-platform web browser developed by its namesake company Opera. The current edition of the browser is based on Chromium. Opera is available on Windows, macOS, Linux, Android, and iOS (Safari WebKit engine). Opera offers two mobile versions, called Opera Mobile and Opera Mini.

Opera was first developed at the Norwegian Telecommunications Agency, as part of the MultiTorg project. After four beta versions, the first stable version was released on 10 April 1995, making it one of the oldest desktop web browsers to exist. It was commercial software for its first ten years and had its own proprietary layout engine, Presto. In 2013, it switched from the Presto engine to Chromium.

Open-source software development (OSSD) is the process by which open-source software, or similar software whose source code is publicly available, is developed by an open-source software project. These are software products available with its source code under an open-source license to study, change, and improve its design. Examples of some popular open-source software products are Mozilla Firefox, Google Chromium, Android, LibreOffice and the VLC media player.
