COCOON

COCOON is a privacy-aware desktop client framework designed by the developers of Telegram to provide a modern, secure, and extensible environment for building messaging and communication applications. At its core, it combines native desktop performance with web-like flexibility, packing a renderer, UI components, and plugin architecture that allows developers to craft rich experiences similar to those found in native apps. Cocoon’s architecture prioritizes privacy and security, making it suitable for applications where user data protection is critical, and its modular design lets teams include or exclude features as needed without bloating the core system. The framework abstracts platform-specific details, enabling cross-platform development for Windows, macOS, and Linux with consistent behavior and performance. In addition to UI framework components, Cocoon provides networking primitives optimized for real-time communication, background updating, and seamless offline support.
