Helios Sync Server^beta

The Helios Sync Server powers secure, end-to-end encrypted synchronization for Helios—the blazing fast, privacy-first LLM chat client. This Go-based backend is designed for speed, simplicity, and zero-knowledge privacy: your data is always encrypted client-side, and the server never sees your secrets.

🚀 Features

• Zero-Knowledge Sync: All chat data is encrypted in your browser. The server only stores encrypted blobs—no plaintext, no metadata, no user accounts.
• Stateless Authentication: Sync with a passphrase—no registration, no email, no tracking.
• Lightning Fast: Built with Go and Redis for maximum performance and reliability.
• Simple API: Minimal, well-documented endpoints for easy integration with the Helios frontend.
• Open Source: MIT licensed and ready for your contributions.
