architecture Dual-Engine Web Architecture: The Engineering Story Behind WebK & WebZ
In 2021, Telegram held a public contest inviting world-class frontend engineers to build a next-generation lightweight web client. Rather than choosing just one winner, Telegram adopted both finalists: Telegram WebK and Telegram WebZ.
Both versions connect directly to Telegram's MTProto protocol using WebSocket Secure (
wss://) pipelines. WebK emphasizes classic design fidelity and granular customization, while WebZ features ultra-smooth animations, fluid swipe physics, and a minimalist design.
