Genthux Diginesia — origin story our story & engineering philosophy

BUILT BY SYSADMINS
TIRED OF RENT
& BLOAT.

At Genthux Diginesia we build native desktop software engineers truly own. No forced monthly rents, no cloud in the middle, sub-16ms keystroke performance. Community Core is 100% free forever — personal, commercial, enterprise production.

[ origin — the uncomfortable compromise ]

Two bad choices.
We refused both.

The Modern SaaS Trap

$10–$20/mo recurring subscriptions, bloated 500MB Chromium/Electron views eating 1GB RAM for 3 tabs, and private infrastructure metadata shipped to proprietary multi-tenant clouds.

The Legacy Stagnation

Old 32-bit utilities were fast but frozen in time — no visual port-forwarding canvas, no jump-host chaining, no OSC 7 live file sync, no native Linux desktop parity.

The birth of Termetra

We founded Genthux Diginesia to kill that compromise. Compiled natively — C# / WinUI 3 + DirectX on Windows, GTK4 / Libadwaita on Linux. Anti-subscription to the bone: Community Core free forever; specialist add-ons like Vault Screen Locking and Self-Hosted Team Sync sold as perpetual lifetime licenses that run 100% offline.

The Genthux Diginesia Guarantee

No telemetry. No analytics sold. No core terminal capability behind a paywall. Passwords, private keys and topology stay on your disk.

THE ARCHITECTURE
POWERING TERMETRA.

Shared Rust Core

Async SSH/SFTP on memory-safe audited russh crates.

Windows WinUI 3 Native

Fluent Design, DirectX 12 terminal rendering, Mica materials. Zero Electron.

Linux GTK4 + Libadwaita

First-class Linux packages + Flatpak, dark-theme + Wayland correct.

SQLCipher v3 Vault

AES-256-GCM + Argon2id stretching, RAM zeroization after handshakes.

Zero-compromise speed

Compiled code on system graphics APIs. Fast launch, 45MB idle, smooth under massive scrollback.

Data sovereignty

Keys never touch our servers. Sync is 100% self-hosted, encrypted client-side with CPace PAKE.

Fair perpetual licenses

Buy once, use offline forever. No sneaky rebills, no connection-count traps.

free forever — no card, no account to start
