🌈 Highlights

Termlnk combines a fast smart terminal, an SSH & SFTP client, and a built-in AI assistant that can execute commands for you — all in one app. Use it on your desktop, or self-host it and open it in any browser.

  • 🖥 All your terminals in one window — open local shells and SSH sessions side by side, split panes flexibly, magnify a single pane when you need focus, and let Termlnk restore your workspace after a restart.
  • 🔐 Servers, keys and files in one place — organize servers in a folder tree, log in with a password, key or ssh-agent (jump hosts included), and browse or transfer remote files with a dual-pane SFTP browser. All SSH keys and known hosts are centralized in the keychain page.
  • 🔀 Port forwarding — expose a local service to a remote server, map a remote service back to your machine, or use any SSH connection as a SOCKS5 proxy. All configured in the UI and toggled with one click.
  • ✂️ Snippets — save commands you use often, organize them into groups, and run them in any session with a single click. Attach a snippet to a server and it runs the moment you connect.
  • 🤖 AI Agent — chat with OpenAI, Claude, Gemini, DeepSeek, Qwen or any OpenAI-compatible model, and switch freely between them. With your approval, it can run terminal commands on your behalf and stays coherent during long conversations.
  • ☁️ Cross-device sync, end-to-end encrypted — servers, keys, snippets and port-forwarding rules sync automatically across your devices. Data is encrypted on your device before it leaves, and your master password can be changed at any time without losing existing data.
  • 🔄 In-app auto-updates — check, download and install new releases in one click from Settings, on macOS, Windows and Linux.
  • 🧩 Extension marketplace — install extensions in one click to add commands, menus, side panels or settings. Developers can build custom extensions with a stable TypeScript API.
  • 🎨 71 themes, or bring your own — pick from 71 built-in themes with a live-preview editor, or set separate light and dark themes and let Termlnk follow the system automatically. Blur, transparency, fonts and keyboard shortcuts are all customizable.
  • 💻 Cross-platform & offline-first — proper installers for macOS (Intel & Apple Silicon), Windows and Linux. No internet connection required.
  • 🌐 Also runs in a browser — deploy the same app to your own server with one Docker command, HTTPS included, then use it from any modern browser with the same experience as the desktop.
  • 🏝 Dynamic Island on macOS — on notch-equipped Macs, the top pill area shows live AI status, complete with sounds for start, completion, approval needed and errors.

🚀 Quick Start

Download

Prebuilt installers for macOS, Windows and Linux (x64 & arm64) are published on the GitHub Releases page. The desktop app self-updates from Settings once installed.

Build from source

git clone https://github.com/termlnk/termlnk.git
cd termlnk
pnpm install

cd apps/desktop
pnpm dev

Package installers

cd apps/desktop
pnpm make:mac      # macOS .dmg / .zip (x64 & arm64)
pnpm make:win      # Windows .exe / .msi (x64 & arm64)
pnpm make:linux    # Linux .AppImage / .deb / .rpm (x64 & arm64)

💻 Platform & Installation Notes

macOS builds are code-signed with a Developer ID certificate but not notarized, so Gatekeeper may still prompt on first launch. Windows and Linux builds are unsigned.

Option 1 — Right-click Termlnk.app in Finder > Open > confirm.

Option 2 — System Settings > Privacy & Security > scroll to Security > click Open Anyway.

Option 3 — Run in Terminal:

xattr -cr /Applications/Termlnk.app

Option 1 — Click "More info" on the SmartScreen dialog, then "Run anyway".

Option 2 — Settings > Apps > Advanced app settings > set App Install Control to allow apps from anywhere.

🌐 Web Edition (Self-Hosting)

termlnk-web is a self-hosted version of the same app that runs in the browser. Your terminals, servers, AI assistant and SFTP work exactly as they do on the desktop — the only difference is that you open a URL instead of launching a desktop client.

⚠ Only run termlnk-web on a machine you trust. It holds your master password and can connect to your servers, invoke AI, and read files on the host machine — it has the same privileges as the desktop app. Do not expose it to the public internet without protection.

Prebuilt multi-arch images (amd64 / arm64) are published to GHCR — no need to clone the monorepo.

cd apps/web

# One-click: generate a strong master password, pull the image, start, health-check
./install.sh

# With automatic HTTPS (built-in Caddy + Let's Encrypt)
./install.sh --tls termlnk.example.com

Or deploy manually with Docker Compose:

cd apps/web
printf '%s' 'choose-a-strong-passphrase' > master_password.secret && chmod 600 master_password.secret
docker compose up -d

See the termlnk-web deployment guide for one-click & manual deployment, reverse-proxy (Caddy / nginx) configs, environment variables, data persistence, upgrades, and the security checklist.
