Blazing fast, local-first, Zero-Knowledge SSH & SFTP client.
Free • Open Source • No Account Required
— why voltius
Built for engineers who care about their tools
Every feature exists because the alternatives were either missing it or locked it behind a paid tier.
Local-first forever
No account required. Works fully offline. Your data lives on your machine, not our servers.
No vendor lock-in
Import existing data from supported sources (Termius, MobaXterm, etc.). Your data is always exportable as open JSON.
Zero-knowledge E2EE sync
Your data is encrypted locally before leaving your device. We can't read it — and neither can attackers.
Native Rust performance
Built with Tauri + Rust. No Chromium overhead, snappy UI, tiny install footprint.
Cross-platform sync
Sync your connections, credentials, and settings across all your devices with end-to-end encryption.
SFTP with drag & drop
Transfer files between local, remote, or host-to-host with a native drag & drop interface.
Plugin system
Extend Voltius with first-party and community plugins. Gist Sync, process manager, and more.
Container management
Docker and Proxmox LXC. Browse containers, open terminals, manage resources — without leaving Voltius.
Audit logs
Review recent vault activity without leaving your workspace.
Fully open source — AGPLv3
AGPLv3Every component — client, server, and crypto — is fully open source under AGPLv3. Audit the code, fork it, contribute back, or self-host the entire stack.
