Mozilla Thunderbird is a free and open-source email client software which also functions as a full personal information manager with a calendar and contactbook, as well as an RSS feed reader, chat client (IRC/XMPP/Matrix), and news client. Available cross-platform, it is operated by the Mozilla Foundation's subsidiary MZLA Technologies Corporation. Thunderbird is an independent, community-driven project that is managed and overseen by the Thunderbird Council, which is elected by the Thunderbird Community. The project strategy was originally modeled after that of Mozilla's Firefox Web browser and is an interface built on top of that Web browser.
This is a comparison of both historical and current web browsers based on developer, engine, platform(s), releases, license, and cost.
The following tables compare general and technical features of notable email client programs.
Mozilla Firefox has features which distinguish it from other web browsers, such as Google Chrome, Safari, and Microsoft Edge.
Zotero is free and open-source reference management software to manage bibliographic data and related research materials, such as PDF and ePUB files. Features include web browser integration, online syncing, generation of in-text citations, footnotes, and bibliographies, integrated PDF, ePUB and HTML readers with annotation capabilities, and a note editor, as well as integration with the word processors Microsoft Word, LibreOffice Writer, and Google Docs. It was originally created at the Center for History and New Media at George Mason University and, as of 2021, is developed by the non-profit Corporation for Digital Scholarship.
Zarafa was an open-source groupware application that originated in the city of Delft in the Netherlands. The company that developed Zarafa, previously known as Connectux, is also called Zarafa. The Zarafa groupware provided email storage on the server side and offered its own Ajax-based mail client called WebAccess and a HTML5-based, WebApp. Advanced features were available in commercially supported versions. Zarafa has been superseded by Kopano.
Google Chrome is a 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, and also for Android, where it is the default browser. The browser is also the main component of ChromeOS, where it serves as the platform for web applications.
Google Native Client (NaCl) is a discontinued sandboxing technology for running either a subset of Intel x86, ARM, or MIPS native code, or a portable executable, in a sandbox. It allows safely running native code from a web browser, independent of the user operating system, allowing web apps to run at near-native speeds, which aligns with Google's plans for ChromeOS. It may also be used for securing browser plugins, and parts of other applications or full applications such as ZeroVM.
Chromium is a free and open-source web browser project, primarily developed and maintained by Google. It is a widely-used codebase, providing the vast majority of code for Google Chrome and many other browsers, including Microsoft Edge, Samsung Internet, and Opera. The code is also used by several app frameworks.
ChromeOS, sometimes styled as chromeOS and formerly styled as Chrome OS, is a Linux distribution developed and designed by Google. It is derived from the open-source ChromiumOS, based on the Linux kernel, and uses the Google Chrome web browser as its principal user interface.
HTML video is a subject of the HTML specification as the standard way of playing video via the web. Introduced in HTML5, it is designed to partially replace the object element and the previous de facto standard of using the proprietary Adobe Flash plugin, though early adoption was hampered by lack of agreement as to which video coding formats and audio coding formats should be supported in web browsers. As of 2020, HTML video is the only widely supported video playback technology in modern browsers, with the Flash plugin being phased out.
The Chromium Embedded Framework (CEF) is an open-source software framework for embedding a Chromium web browser within another application. This enables developers to add web browsing functionality to their application, as well as the ability to use HTML, CSS, and JavaScript to create the application's user interface.
Chrome Remote Desktop is a remote desktop software tool, developed by Google, that allows a user to remotely control another computer's desktop through a proprietary protocol also developed by Google, internally called Chromoting. The protocol transmits the keyboard and mouse events from the client to the server, relaying the graphical screen updates back in the other direction over a computer network. This feature, therefore, consists of a server component for the host computer, and a client component on the computer accessing the remote server. Chrome Remote Desktop uses a unique protocol, as opposed to using the common Remote Desktop Protocol.
Mozilla is a free software community founded in 1998 by members of Netscape. The Mozilla community uses, develops, publishes and supports Mozilla products, thereby promoting exclusively free software and open standards, with only minor exceptions. The community is supported institutionally by the non-profit Mozilla Foundation and its tax-paying subsidiary, the Mozilla Corporation.
Proton Mail is a Swiss end-to-end encrypted email service founded in 2013 headquartered in Plan-les-Ouates, Switzerland. It uses client-side encryption to protect email content and user data before they are sent to Proton Mail servers, unlike other common email providers such as Gmail and Outlook.com. The service can be accessed through a webmail client, the Tor network, Windows, macOS and Linux (beta) desktop apps and iOS and Android apps.
Vivaldi is a freeware, cross-platform web browser with a built-in email client developed by Vivaldi Technologies, a company founded by Tatsuki Tomita and Jon Stephenson von Tetzchner, who was the co-founder and CEO of Opera Software. Vivaldi was initially released on 27 January 2015.
Kopano is an open-source groupware application suite originally based on Zarafa. The initial version of Kopano Core (KC) was forked from the then-current release of Zarafa Collaboration Platform, and superseded ZCP in terms of lineage as ZCP switched to maintenance mode with patches flowing from KC. Kopano WebApp similarly descended from Zarafa WebApp. Since October 2017, Kopano Core is also known more specifically as Kopano Groupware Core, since Kopano B.V. developed more products that were not directly requiring groupware components.
Bitwarden is a freemium open-source password management service that is used to store sensitive information, such as website credentials, in an encrypted vault. The platform hosts multiple client applications, including a web interface, desktop applications, browser extensions, mobile apps, and a command-line interface. The platform offers a free US or European cloud-hosted service as well as the ability to self-host.
