telegram.org Reviews

Telegram is a cloud-based instant messaging and voice over IP service. It was founded by the Russian entrepreneur Pavel Durov and his brother Nikolai. Telegram client apps are available for Android, iOS, Windows Phone, Windows NT, macOS, and Linux. Users can send messages and exchange photos, videos, stickers, audio, and files of any type. Telegram's client-side code is open-source software but the source code for recent versions is not always immediately published, whereas its server-side code is closed-source and proprietary. The service also provides APIs to independent developers. In February 2016, Telegram stated that it had 100 million monthly active users, sending 15 billion messages per day. According to the company, as of April 2020, Telegram reached 400 million monthly active users. Telegram has been widely used for various purposes, including as a secure messaging app for activists, whistleblowers, and journalists. Telegram has been described as a secure and private messaging app, but this has been disputed by some security researchers. The app has faced criticism and controversy, particularly over its encryption and privacy features, and has been banned in some countries. Telegram has also been used by extremist groups and for illegal activities, leading to concerns about its security and the spread of harmful content. Despite these issues, Telegram remains popular and continues to be used by millions of people around the world."
