# TerminalX.sh

> TerminalX.sh is a local-first SSH, SFTP, Mosh, Telnet and Serial client for macOS, Windows and Linux. Pay once (from $9 during the launch), own it for life: no subscription, no account, no telemetry. Hosts, keys and snippets live in an encrypted vault on your machine (Argon2id + XChaCha20-Poly1305). Built with Tauri, not Electron.

Key facts:
- One-time pricing: $9 for the first 500 licenses, $19 for the next 250, then $29 standard. Every future update included. 14-day refund via Polar.
- Protocols: SSH (password, key, certificate, agent, keyboard-interactive/2FA prompts, passphrase prompts, jump hosts, agent forwarding, port knocking), SFTP (dual-pane), Mosh, Telnet, Serial, plus port forwarding (local/remote/dynamic SOCKS5) and port knocking.
- Local-first: no account, no cloud vault, no sync requirement, no analytics. Works offline.
- License check: the app activates your Polar license key on first run and re-validates it once a week (a revoked key locks the app until an active key is entered); between checks it runs fully offline.
- Migrations: importers for ~/.ssh/config, PuTTY, SecureCRT, MobaXterm, CSV and Termius exports (best-effort, reverse-engineered format).
- Platforms: macOS, Windows, Linux. One license covers the machines you personally use.
- Not shipped yet: cross-device sync, team vaults, collaboration, audit logs, managed AI.
