Peergos
Peergos provides quantum-resistant encrypted storage, sharing, and sync with no tracking or ads. Your files and metadata remain private, even from the server. Fully open-source and self-hostable.
Peergos is a secure, private space for storing, sharing, and syncing your files with end-to-end encryption. Unlike traditional cloud services, Peergos ensures your data and metadata remain completely private, even from the server itself.
Key Features
- Quantum-resistant encryption: Files are protected with post-quantum cryptography, safeguarding against future threats
- Zero-knowledge architecture: Metadata like file sizes, directory structure, and contacts remain hidden from everyone, including Peergos
- Cross-device sync: Synchronize files across multiple devices with end-to-end encrypted backups
- Portable identity: Your identity is independent of any single server, allowing migration without losing data or connections
- Offline access: View recent files entirely offline without compromising security
- Social features: Share files securely with friends and manage a private social feed
- Open-source: All code is publicly available for independent verification and self-hosting
- Trustless system: Your data remains safe regardless of where Peergos runs
Tech / Self-Hosting
Peergos is fully open-source and can be self-hosted on your own infrastructure. The project provides comprehensive documentation for deployment and maintenance. Security audits by Cure53 and Radically Open Security confirm the robustness of the system. The peer-to-peer protocol enables interoperability between different Peergos instances, allowing users on any server to connect and share securely.
Peergos has been supported by organizations including the Next Generation Internet Program, Protocol Labs, FUTO, and the Oxford Foundry.
