Every registered device exposes a terminal, a file manager, and (optionally) a public URL — all reachable straight from the dashboard, over the same reverse tunnel used for everything else. No SSH keys to distribute, no exposed ports on the device.

​
Terminal

Open a real interactive shell on the device from your browser — full PTY support (resizing, colors, interactive programs like top or vim all work normally). Useful for anything the dashboard doesn’t have a dedicated UI for.

​
File Manager

Browse, upload, download, rename, and delete files on the device’s filesystem directly from the dashboard.
  • Downloads support resuming and show progress (bytes transferred / total).
  • Uploads are capped at 100MB per file and show progress the same way.
  • Both are backed by SFTP under the hood, so large transfers don’t need to be buffered entirely in memory on either end.

​
Public URLs

Expose a port running on the device (a web app, an API, anything listening on localhost) at a public https:// URL, without opening any inbound firewall rule on the device. Each device gets 3 public URL slots. To use one:
  1. From the device’s page, open the Public URL panel.
  2. Enter the local port you want to expose (e.g. 8080).
  3. IoT Manager assigns a URL like {hash}-{slot}.iotmanager.dev and starts forwarding traffic to that port on the device.
Traffic flows: https://{hash}-{slot}.iotmanager.dev → IoT Manager → reverse tunnel → the device’s localhost:<port>. The device never needs to accept inbound connections for this to work.

​
Container control

If the device has Docker installed, the Services panel shows running containers with Start/Stop/Restart buttons and log viewing, without needing the terminal at all.
Terminal, file manager, and telemetry all work whether or not the device has Docker — only the Services/container panel depends on it.
