Voltius

Voltius is a desktop SSH and SFTP client built with Rust and Tauri, designed for engineers who want privacy and control over their connection data. It requires no account, works fully offline, and stores all data locally on your machine with optional end-to-end encrypted sync across devices via GitHub Gist, Cloudflare, or S3. The project describes itself as a modern alternative to Termius.

Key features include persistent tmux/screen-backed sessions that survive network drops, native drag-and-drop file transfers, split panes with broadcast input, Docker and Proxmox container management, a plugin system, and an MCP server for integration with Claude and code editors. The entire codebase is open source under AGPLv3, fully auditable and self-hostable.
