GNUnet

Self-Hosted

Decentralized, privacy-preserving communication framework with built-in security

Overview

GNUnet is a decentralized, privacy-first communication framework designed to eliminate central points of failure. It enables secure peer-to-peer messaging, file sharing, and voice calls with end-to-end encryption. Deployable as a node on Linux, BSD, macOS, or via community Docker images, it prioritizes user autonomy by avoiding centralized servers. Key features include anonymous routing to prevent surveillance, censorship resistance, and protection against man-in-the-middle attacks—ideal for users seeking control over their communication data.

Frequently Asked Questions

? Is GNUnet hard to install?

GNUnet can be installed via package managers on Linux/BSD systems or from source. Community Docker images simplify deployment for beginners, though configuring advanced features like anonymous routing may require basic technical knowledge.

? Is it a good alternative to WhatsApp or Telegram?

Yes—if you prioritize privacy and decentralization over mainstream features like large group chats or stickers. GNUnet avoids central servers, so your data isn’t stored on third-party infrastructure, unlike WhatsApp/Telegram.

? Is GNUnet completely free?

Yes! GNUnet is open-source software licensed under the GNU General Public License (GPL), meaning it’s free to use, modify, and distribute without any cost.
