Browser SSH Terminal Web UI

SSH into remote machines directly from your browser. The NFLTR dashboard includes a full-featured xterm.js terminal — no SSH client installation, no key management, no port forwarding. Just click "Connect" on any agent with SSH enabled.


How It Works

The browser connects to the NFLTR server over a WebSocket. The server bridges the WebSocket to the SSH tunnel established by the agent. The agent proxies SSH to the target machine. Full interactive terminal with colors, resize, and scrollback.

How to Enable

On the agent

nfltr tcp 22 --name my-ssh-server

# Or forward to a specific SSH server on the network
nfltr tcp 22 --forward 192.168.1.100:22

From the dashboard

  1. Sign in to your NFLTR dashboard
  2. Find the agent in your Agents list
  3. Click the SSH button next to the agent name
  4. A terminal window opens in your browser
💡 Also works from CLI

Prefer a local terminal? Use nfltr ssh-proxy --name <agent-id> from any machine with the CLI installed. See TCP & SSH Tunneling for details.
