Serial + RDP/VNC tabs.

COM/UART for switches, GUI desktops docked natively.

[ 02 — under the hood ]

BUILT LIKE
INFRASTRUCTURE.

Four layers, zero middlemen. Every keystroke travels from your keyboard to the server without touching anyone else's cloud.

01

Shared Rust core

Async SSH/SFTP on memory-safe, audited russh crates. One core, two native shells.

02

Truly native shells

WinUI 3 + DirectX on Windows, GTK4 + Libadwaita on Linux. Sub-16ms PTY, ~48MB idle.

03

Local-only vault

Profiles and keys sealed in SQLCipher AES-256-GCM with Argon2id stretching. RAM zeroized after handshakes.

04

Your infra only

Sync goes to your Docker — or nowhere (air-gap). The vendor sees 0 packets.

[ 03 — honest fight ]

STOP
PAYING
RENT.

Typical SaaS clients charge ~$120/yr to store your keys on their cloud. Legacy suites never left Windows. We chose the third way: free core + pay-once add-ons you actually own.

Self-hosted sync sold my CISO in 5 minutes. Keys never leave our VPC.

SWITCH IN
60 SECONDS.

Your sessions, jump chains, and keys come with you. Nothing to retype, nothing left behind.

STEP 1

Point at your source

Pick up ~/.ssh/config, a PuTTY .reg export, or a .mxtpro file. No export gymnastics.

STEP 2

One-click import

Hosts, tags, jump inheritance, and key references land intact — 86 hosts in a single click.

STEP 3

Verify & go

Connections self-test on first launch. Then uninstall the old app with confidence.

[ 06 — straight answers ]

ASKED OFTEN.

Is the core really free forever?

Yes — for personal, educational, commercial, and enterprise use. No account, no card, no host cap. Specialist add-ons are pay-once lifetime licenses, never subscriptions.

Do my keys ever leave my machine?

No. Profiles and private keys live in a local SQLCipher AES-256 vault. Team sync replicates only to infrastructure you run yourself — verify the silence with Wireshark.

How do add-ons work offline?

You receive a cryptographic .lic file or key, paste it under Settings › Add-Ons, and the feature unlocks permanently. No phone-home, ever.

Which platforms are supported?

Native builds for Windows 10/11 and Linux — with distro-agnostic coverage for Debian, Fedora, Arch, openSUSE, and Alpine.

Can I migrate from my current client?

In about a minute. One-click import covers ~/.ssh/config, PuTTY .reg exports, and MobaXterm profiles — hosts, tags, and jump chains included.
