Termox cross-platform desktop SSH terminal and server administration workbench

A Unified Desktop Server Workbench

Termox is a cross-platform desktop SSH terminal, remote file manager, server administration workbench, and AI-assisted system operations client actively developed by COS Q Network.

Built with Avalonia UI and .NET 10, it brings together high-performance terminal emulation, SFTP file management, in-place remote editing, systemd and certbot automation, network diagnostics, and an extensible LLM chat assistant ("Helm") into a fast, native desktop experience for Windows, macOS, and Linux.

High-Performance Terminal & Side-by-Side Workspace

Termox tabbed SSH terminal emulation and split view workspace

Concurrent Tabbed Sessions: Run multiple independent SSH connections with ANSI color rendering, dark-theme ergonomics, session restoration across restarts, and instant tab duplication.

Flexible Authentication & Keep-Alives: Connect via passwords, OpenSSH private keys (RSA, ED25519) with dedicated passphrases, configurable keep-alive heartbeats to prevent NAT drops, and automated reconnection policies.

Side-by-Side Split View: Pin any tab into a secondary split pane to monitor server metrics while executing terminal commands or browsing remote files.

Browser-Style Navigation & Profiles: Retrace tab navigation with back/forward history, organize credentials into reusable connection profiles, and bookmark frequently accessed remote directories.

Remote Filesystem Management & In-Place Editing

Termox SFTP remote file browser and in-place code editor

Integrated SFTP Explorer: Navigate remote directory trees, filter files with instant text search, inspect file attributes, and perform single or bulk transfers with path confinement safeguards.

In-Place Remote Text Editing: Open and edit remote configuration files and scripts directly using an embedded AvaloniaEdit editor with dirty-state tracking, quick read-only previews, and discard confirmations.

Safety Guards & Permissions: Configurable threshold warnings prompt confirmation before large file transfers, paired with an interactive octal Unix permissions editor (chmod).

Server-to-Server File Transfers: Transfer files directly between two remote SSH servers in relay mode (streamed in-memory) or execute high-speed direct transfers via remote rsync/scp.

Helm: AI-Assisted System Operations

Termox Helm AI chat assistant with tool calling and approval gates

Custom Inference Endpoints: Connect to any OpenAI-compatible provider (Ollama, LM Studio, OpenRouter, Groq, or OpenAI) with live token streaming and rich visual Markdown rendering.

15+ Native Admin Tools: Helm inspects and operates your infrastructure using native Termox capabilities — executing non-interactive shell commands, querying systemd services, reading logs, scanning ports, and managing SSL certificates.

3-Tier Risk Security Model: Read-only operations run immediately, state-mutating actions require explicit confirmation banners, and destructive commands are strictly guarded.

Encrypted Local Persistence: All chat sessions, messages, and tool invocations are encrypted at rest in local SQLite using platform credential protection (ChatContentCipher).

Built-In Server Tools & Zero-Plaintext Security

Termox server stats dashboard, systemd manager, and diagnostic utilities

Live Server Stats & Systemd: Real-time CPU, memory, top processes, and disk utilization dashboards, alongside Linux systemd unit management with quick-action service chips.

Certbot SSL/TLS Automation: Automate Let's Encrypt certificate issuance, renewal, and revocation over SSH across Nginx, Apache, Standalone, and Webroot plugins with safe dry-runs.

Network & Cryptographic Diagnostics: DNS record inspector, multi-port TCP scanner, ICMP ping testing, SSH key generation, and MD5/SHA fingerprint utilities.

Zero-Plaintext Security: Passwords and keys are protected at rest via Windows DPAPI, macOS Keychain, or Linux Secret Service, backed by strict Host-Key Pinning and zero telemetry.
