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. It was later ported to Linux, macOS, iOS, and Android, where it is the default browser. The browser is also the main component of Chrome OS, where it serves as the platform for web applications.

As of October 2021, StatCounter estimates that Chrome has a 68% worldwide browser market share (after peaking at 72.38% in November 2018) on personal computers (PC), is most used on tablets (having surpassed Safari), and is also dominant on smartphones, and at 65% across all platforms combined.

Safari is a graphical web browser that is developed by Apple. It is primarily based on open-source software properties, and mainly WebKit. It succeeded Netscape Navigator, Cyberdog and the most recent Internet Explorer for Mac as the default web browser for Macintosh computers. It is supported on macOS, iOS, and iPadOS; a Windows version was offered from 2007 to 2010.

Safari was introduced within the Mac OS X Panther in January 2003, and as of 2021, spawned a total of 15 revisions. The third generation (January 2007) brought compatibility to the iPhone via iPhone OS 1, while the Macintosh edition was topped with the fastest browser performance at that time. The fifth version (June 2010) made uses of a less distracted screen reader, extension and developer tools; it was also the final version for Windows. In the eleventh version (September 2017), it added supports for the Intelligent Tracking Prevention. The thirteenth version included various privacy and application updates such as the FIDO2 USB security key authentication and Web Apple Pay support. The fourteenth version (November 2020) was the most-previous revision of Safari. The 2020 version was 50% faster than Google Chrome, and it consumed less battery than other standard competitors. The fifteenth version (July 2021) was the current revision, featuring a redesigned interface.

Mozilla Firefox or simply Firefox is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Firefox uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface. Firefox is available for Windows 7 and later versions, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. Firefox is also available for Android and iOS. However, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements, as with all other iOS web browsers. An optimized version of Firefox is also available on the Amazon Fire TV, as one of the two main browsers available with Amazon's Silk Browser.

Microsoft Edge is a cross-platform web browser created and developed by Microsoft. It was first released for Windows 10 and Xbox One in 2015, for Android and iOS in 2017, for macOS in 2019, and for Linux in 2020, and can replace Internet Explorer on Windows 7, Windows Server 2008 R2 and later versions but unlike IE, this browser does not support Windows Vista or earlier versions.

The Chromium-based Edge replaced Internet Explorer (IE) in Windows 11, as the default web browser (for compatibility with Google Chrome web browser).

Edge was initially built with Microsoft's own proprietary browser engine EdgeHTML and their Chakra JavaScript engine, a version now referred to as Microsoft Edge Legacy. In 2019, Microsoft announced plans to rebuild the browser as Chromium-based with Blink and V8 engines. During development (codenamed Anaheim), Microsoft made preview builds of Edge available on Windows 7, 8/8.1, 10, and macOS.

Google Search, or simply Google, is a web search engine developed by Google LLC. It is the most used search engine on the World Wide Web across all platforms, with 92.16% market share as of December 2020, handling more than 5.4 billion searches each day.

The order of search results returned by Google is based, in part, on a priority rank system called "PageRank". Google Search also provides many different options for customized searches, using symbols to include, exclude, specify or require certain search behavior, and offers specialized interactive experiences, such as flight status and package tracking, weather forecasts, currency, unit, and time conversions, word definitions, and more.

The main purpose of Google Search is to search for text in publicly accessible documents offered by web servers, as opposed to other data, such as images or data contained in databases. It was originally developed in 1997 by Larry Page, Sergey Brin, and Scott Hassan. In June 2011, Google introduced "Google Voice Search" to search for spoken, rather than typed, words. In May 2012, Google introduced a Knowledge Graph semantic search feature in the U.S.

Google Docs is an online word processor included as part of the free, web-based Google Docs Editors suite offered by Google, which also includes Google Sheets, Google Slides, Google Drawings, Google Forms, Google Sites, and Google Keep. Google Docs is accessible via an internet browser as a web-based application and is also available as a mobile app on Android and iOS and as a desktop application on Google's Chrome OS.

Google Docs allows users to create and edit documents online while collaborating with other users in real-time. Edits are tracked by user with a revision history presenting changes. An editor's position is highlighted with an editor-specific color and cursor and a permissions system regulates what users can do. Updates have introduced features using machine learning, including "Explore", offering search results based on the contents of a document, and "Action items", allowing users to assign tasks to other users.

Google Maps is a web mapping service developed by Google. It offers satellite imagery, aerial photography, street maps, 360° interactive panoramic views of streets (Street View), real-time traffic conditions, and route planning for traveling by foot, car, bicycle, air (in beta) and public transportation. In 2020, Google Maps was used by over 1 billion people every month.

Google Maps began as a C++ desktop program at Where 2 Technologies. In October 2004, the company was acquired by Google, which converted it into a web application. After additional acquisitions of a geospatial data visualization company and a real time traffic analyzer, Google Maps was launched in February 2005. The service's front end utilizes JavaScript, XML, and Ajax. Google Maps offers an API that allows maps to be embedded on third-party websites, and offers a locator for businesses and other organizations in numerous countries around the world. Google Map Maker allowed users to collaboratively expand and update the service's mapping worldwide but was discontinued from March 2017. However, crowdsourced contributions to Google Maps were not discontinued as the company announced those features would be transferred to the Google Local Guides program.

Google Maps' satellite view is a "top-down" or bird's-eye view; most of the high-resolution imagery of cities is aerial photography taken from aircraft flying at 800 to 1,500 feet (240 to 460 m), while most other imagery is from satellites. Much of the available satellite imagery is no more than three years old and is updated on a regular basis. Google Maps previously used a variant of the Mercator projection, and therefore could not accurately show areas around the poles. In August 2018, the desktop version of Google Maps was updated to show a 3D globe. It is still possible to switch back to the 2D map in the settings.

Google Maps for Android and iOS devices was released in September 2008 and features GPS turn-by-turn navigation along with dedicated parking assistance features. In August 2013, it was determined to be the world's most popular app for smartphones, with over 54% of global smartphone owners using it at least once.

In 2012, Google reported having over 7,100 employees and contractors directly working in mapping.

Google Photos is a photo sharing and storage service developed by Google. It was announced in May 2015 and spun off from Google+, the company's former social network.

As of June 1, 2021, in its free tier, any newly uploaded photo and video counts towards the 15 GB free storage quota shared across the user's Google services, with the exception of current Pixel phones. The previous free tier, unlimited photos and videos up to 16 megapixels and 1080p resolution respectively (anything larger gets down-scaled to these sizes), ended on the same day.

The service automatically analyzes photos, identifying various visual features and subjects. Users can search for anything in photos, with the service returning results from three major categories: People, Places, and Things. The computer vision of Google Photos recognizes faces (not only those of humans, but pets as well), grouping similar ones together (this feature is only available in certain countries due to privacy laws); geographic landmarks (such as the Eiffel Tower); and subject matter, including birthdays, buildings, animals, food, and more.
