LicenseApache License 2.0[2] is an open source, free software instant messaging client based on the Matrix protocol. is free software and distributed under the Apache License 2.0. Because it uses the federated Matrix protocol, lets the user choose a server to connect to.[3]

Additionally, supports end to end encryption, groups, channels and sharing of files between users.[4] It is available as a web application, as desktop apps for all major operating systems and as a mobile app for Android and iOS.[5] The development of the app is primarily done by the company New Vector Limited, which is also involved in the development of the Matrix protocol itself.[6]

Technology[edit] is built with the Matrix React SDK[7], which is a React based software development kit to ease the development of Matrix clients. is mostly build around web technologies and also uses Electron, a software framework to create desktop applications from web applications, to distribute their desktop clients for Windows, MacOS and Linux. The Android and iOS clients are developed and distributed with the respective platform tools.

On Android the app is available both in the Google Play Store[8] and the free-software only F-Droid[9] Archives, with minor modifications. For instance the F-Droid version doesn't come with the proprietary Google Cloud Messaging plug-in.

History[edit] was originally called Vector[10], when it was released out of beta in July 2016.[11] The app was renamed and rebranded as Riot in September of the same year.[12] The re-brand was done by Canadian brand consultancy LP/AD. [13] In November the first implementation of the Matrix end-to-end encryption was implemented and rolled out as a beta to users.[14]

Features[edit] is well known for the ability to bridge other communications into the app via Matrix, such as IRC, Slack, Telegram and others[15]. Also it integrates voice and video peer-to-peer and group chats via WebRTC. Because it is possible to self-host the app and the chat server behind it, Riot is often recommended by privacy advocates.[16]

Public Reception[edit]

As Riot is the most matured Matrix client, it is recommended as a starting point for new Matrix users, even by the project itself.[17] In the media it is sometimes perceived as an alternative to Slack[6][18][19] or other instant messaging clients[20][21]. Generally Riot seems most popular in open source and free software communities, where it is sometimes recommended because of its federated nature.[22] This technical focus is reflected in the biggest rooms on the Matrix platform, which feature Linux distributions and Cryptocurrency rooms.[23] The app has been downloaded over 100 000 times in the Google Play Store[24], but probably has some additional users, that download it from F-Droid or on other platforms.
