Show HN: Vibivibi – End-to-end encrypted sharing of Coding Agent sessions (vibivibi.com)

Vibivibi has launched a new tool that allows users to securely back up and share coding agent sessions with end-to-end encryption. Compatible with popular coding agents such as Claude Code, Codex CLI, OpenCode, and Pi, Vibivibi enables users to push a session from one machine and seamlessly pull it onto another, resuming their work while ensuring that all data remains encrypted locally. This service is significant for the AI/ML community as it not only facilitates collaboration among developers but also prioritizes user privacy through its zero-access encryption model, meaning even Vibivibi cannot read user sessions. The technical mechanism behind Vibivibi's encryption relies on robust standards, including X25519 for key exchange, AES-256-GCM for data encryption, and scrypt for password-derived key management. Users can send encrypted sessions to teammates, who must register and use Vibivibi to decrypt the content on their own machines. With a free tier supporting two machines and up to 200 MB of storage, Vibivibi makes it easy for teams to track and recover coding sessions while maintaining strict data security. For teams requiring more capacity, upgraded plans offer additional features such as pooled storage and unlimited session transfers.
