— 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 from Termius, MobaXterm, PuTTY, KiTTY, SecureCRT, ZOC or CSV. 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.
Sessions that survive everything
tmux/screen-backed sessions outlive network drops and app restarts — and with cloud sync, the same live terminal can be open on all your devices at once, mirrored in real time.
Plugin system
Extend Voltius with first-party and community plugins. Gist Sync, Cloudflare Sync, S3 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.
End-to-end encrypted sync
Encrypted on your laptop.
Voltius Cloud only ever sees ciphertext.
Decrypted on your phone.
Hosts, keys and settings are encrypted on your device before they leave it. Voltius Cloud syncs them in real time and only ever stores ciphertext. Pro · 14-day free trial, no credit card requiredPrefer your own storage? Gist, Cloudflare R2 and S3 sync stay free, or build your own sync provider as a plugin.
— a look inside
Polished, and fast where it counts
The same client, from a first connection to a shared team vault.
Everything, one keystroke away
Jump to any host, session, snippet, or action from a single command palette.
Organize at scale
Group hosts into folders and label them with tags. Filter by role across your whole fleet.
Split panes & broadcast
Multiplex terminals in a grid and type one command into every pane at once.
Dual-pane SFTP
Move files between local, remote, or host-to-host with native drag & drop.
Team vaults & granular roles
Built-in roles on Teams; custom roles and per-object permissions on Business.
Make it yours
A full theme editor — window colors, borders, and the entire terminal ANSI palette.
