A terminal server for Windows — operated from any browser

TermioWin runs as a lightweight server on your Windows PC. Any browser on the same network can connect, log in with your Windows account, and start using the full set of Windows command-line tools — instantly.

1

Install TermioWin

Download the installer from this page and run it. TermioWin starts a local server on your Windows PC — that's it.

2

Open your browser

Navigate to the TermioWin address from any browser — Chrome, Edge, Firefox. Log in with your Windows password.

3

Use any CLI tool

cmd, PowerShell, Git, Python, Node.js — every command-line tool installed on your Windows PC is available immediately.

cmd.exe PowerShell Git Python Node.js WSL SSH + any installed tool
How TermioWin works: Browser connects to TermioWin server on Windows PC, which runs cmd, PowerShell, Git and other CLI tools

Multiple windows, multiple tasks

Split your terminal into multiple panes and tackle several tasks in parallel. Open additional browser tabs for independent workspaces — each with its own shell sessions, layout, and working directory.

  • Pane splitting — arrange terminals side-by-side or stacked, any way you like
  • Saved layouts — save up to 5 workspace configurations and switch instantly
  • Multi-tab — open new browser tabs for fully independent workspaces, sharing the same server
  • Session persistence — close a tab and reopen it; your sessions are still running

Smarter commands, fewer keystrokes

As you type in the Input Bar, matching suggestions appear instantly — no manual lookup needed. Works for AI CLI slash commands and every supported shell.

  • AI slash commands — type / for instant Claude Code, Gemini CLI, Codex CLI, Copilot, and Cursor completions
  • Shell commands — CMD, PowerShell, Git Bash, and WSL commands suggested by prefix
  • git & gh — full command and subcommand suggestions for git and GitHub CLI
  • 700+ built-in entries — covering all shell profiles, with recently used commands surfaced first

Everything you need, nothing you don't

Built from the ground up for Windows — not ported from Linux or macOS.

Native Windows Authentication

Authenticates with your existing Windows account via LogonUserW. No separate password to remember, no data sent to third-party services.

LogonUserW API

Session Resilience

Close your browser, lose Wi-Fi, or reboot the client — your terminal session keeps running. Reconnect and pick up exactly where you left off.

Output Buffer 256 KB

Ultra-Low Latency

Direct PTY integration with no extra processing layers. Commands execute at native speed, making TermioWin as fast as any local terminal.

Native PTY

Multi-Workspace

Save up to 5 workspace layouts with custom pane splits. Open multiple browser tabs, each with its own independent workspace and history.

Up to 10 workspaces

TLS Encryption

Enable HTTPS with a self-signed certificate generated automatically on first run. Secure remote access over any network with minimal setup.

Self-signed cert

Local-First Privacy

All application processing happens on your machine. The TermioWin application itself includes no telemetry, no cloud sync, and no third-party analytics. Your terminal is yours alone.

Zero telemetry

AI-Ready: MCP Server

Designate one AI assistant running inside TermioWin as a command hub to send instructions to AI assistants in other terminals. The hub AI can also monitor all terminals by reading their output in real time.

MCP Protocol

Auto-Detected Shells

Automatically discovers PowerShell 7, Git Bash, MSYS2, Cygwin, and WSL distributions. Pick from a dropdown — no configuration needed.

CMD · PS7 · Git · WSL

Built-in Viewer Pane

Open Markdown, PDF, HTML, or text files in a terminal pane. File watching auto-refreshes content as files change on disk.

Markdown · PDF · HTML · URL

Prompt Flow & Auto-Approval

Queue multiple prompts and templates, then send them to any AI CLI automatically — one after another. Auto-Approval detects when the AI finishes and fires the next prompt without human interaction.

Professional · Enterprise

Webhook / CI Triggers

Trigger terminal sessions and commands from external systems via HTTP POST. Integrate with GitHub Actions, Jenkins, or any CI/CD pipeline to automatically launch your AI workflow when a build completes.

GitHub Actions · Jenkins · Professional

Snapshots

Automatically saves a Git snapshot of your project folder each time you run a command — so you can roll back to any point in time. Stored in a separate area that does not interfere with your existing repositories.

Auto Git backup · Restore

Designed for corporate environments

TermioWin is built with enterprise security requirements in mind from day one.

Local Processing Only

Authentication and terminal I/O never leave your machine. All data stays within your Windows environment.

SHA-256 Verified Distribution

Every release includes a published SHA-256 checksum so you can verify file integrity before installing. Download directly from our official site — no third-party stores or intermediaries.

No Cloud, No Account

Personal use requires no account, no registration, no email. Enterprise license activation is a one-time event — after that, TermioWin runs fully offline.

Auditable Open Architecture

Single binary, no hidden services. Data stored only in %APPDATA%\TermioWin\. Easy to inspect, easy to uninstall, easy to audit.

The only external connection TermioWin makes is to Lemon Squeezy during initial Enterprise license activation. After activation, the app runs entirely offline. This is disclosed in the Privacy Policy.
