The landscape for instant messaging involves cross-platform instant messaging clients that can handle one or multiple protocols. Clients that use the same protocol can typically federate and talk to one another. The following table compares general and technical information for cross-platform instant messaging clients in active development, each of which have their own article that provide further information.
Facebook is a social networking service originally launched as TheFacebook on February 4, 2004, before changing its name to simply Facebook in August 2005. It was founded by Mark Zuckerberg, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and gradually most universities in the United States and Canada, corporations, and by September 2006, to everyone with a valid email address along with an age requirement of being 13 or older.
WhatsApp is an instant messaging (IM) and voice-over-IP (VoIP) service owned by technology conglomerate Meta. It allows users to send text, voice messages and video messages, make voice and video calls, and share images, documents, user locations, and other content. WhatsApp's client application runs on mobile devices, and can be accessed from computers. The service requires a cellular mobile telephone number to sign up. In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client.
iMessage is an instant messaging service developed by Apple Inc. and launched in 2011. iMessage functions exclusively on Apple platforms – including iOS, iPadOS, macOS, watchOS, and visionOS – as part of Apple's approach to inter-device integration, which has been described by media outlets as a means of achieving vendor lock-in. iMessage is accessed and used using the Messages app client.
Microsoft SwiftKey is a virtual keyboard app originally developed by TouchType for Android and iOS devices. It was first released for Android in July 2010, followed by an iOS release in September 2014 after Apple's implementation of third-party keyboard support.
Messenger, also known as Facebook Messenger, is an American proprietary instant messaging service developed by Meta Platforms. Originally developed as Facebook Chat in 2008, the client application of Messenger is currently available on iOS and Android mobile platforms, Windows and macOS desktop platforms, through the Messenger.com web application, and on the standalone Facebook Portal hardware.
Snapchat is an American multimedia instant messaging app and service developed by Snap Inc., originally Snapchat Inc. One of the principal features of Snapchat is that pictures and messages are usually only available for a short time before they become inaccessible to their recipients. The app has evolved from originally focusing on person-to-person photo sharing to presently featuring users' "Stories" of 24 hours of chronological content, along with "Discover", letting brands show ad-supported short-form content. It also allows users to store photos in a password-protected area called "My Eyes Only". It has also reportedly incorporated limited use of end-to-end encryption, with plans to broaden its use in the future.
A sticker is a detailed illustration of a character that represents an emotion or action that is a mix of cartoons and Japanese smiley-like "emojis" sent through instant messaging platforms. They have more variety than emoticons and have a basis from internet "reaction face" culture due to their ability to portray body language with a facial reaction. Stickers are elaborate, character-driven emoticons and give people a lightweight means to communicate through kooky animations.
Telegram Messenger, commonly known as Telegram, is a cloud-based, encrypted, cross-platform, instant messaging (IM) service. It was originally launched for iOS on 14 August 2013 and Android on 20 October 2013. It allows users to exchange messages, share media and files, and hold private and group voice or video calls as well as public livestreams. It is available for Android, iOS, Windows, macOS, Linux, and web browsers. Telegram also offers end-to-end encryption in voice and video calls, and in optional private chats, which Telegram calls Secret Chats.
