Support

Browser-based PowerShell and shared Windows terminals from one host.

Browser-based PowerShell

TermiWeb prefers PowerShell 7 when available and falls back to Windows PowerShell when needed, so the browser surface stays useful on real Windows hosts.

Shared browser instances

Open shared terminal instances through the browser UI and attach to the same live shell from more than one device.

Windows installer

Optional auto-start can run before you sign in.

Authenticated browser sessions

Use one configured app password for local and LAN access, with browser sessions that survive normal server restarts until logout or expiry.

Shared width per instance

Each instance keeps one shared column width across attached devices, with 80 columns as the default starting point for consistent terminal sizing when switching devices.

Phone-friendly controls

Mobile controls, selection mode, copy handling, and the fallback paste field are all built into the browser UI.

Screenshots

The same Windows shell, two different browser surfaces.

SmartScreen

“Windows protected your PC” is expected.

The installer is not code-signed yet, so Windows SmartScreen blocks its first launch. Choose More info, then Run anyway. The Windows elevation prompt follows, because TermiWeb installs to Program Files and runs elevated shells.

First Run

Just Run the Installer

Run the installer. If SmartScreen appears, choose More info, then Run anyway, and approve the Windows elevation prompt.
Read the disclaimer page, then choose the TermiWeb password. Every browser that connects enters it.
Decide whether TermiWeb starts before sign-in. That startup task runs as SYSTEM; no Windows account password is requested.
Let the finish page start TermiWeb and open http://127.0.0.1:22443.
From another device on the same LAN, browse to the host device’s LAN URL to attach to the same live shell. The installer already allowed the port through the firewall on every network profile.

Trust

Built for a trusted private network.

Windows hosts only

Targets Windows hosts and uses an elevated-only shell path.

Trusted-network-first

The intended default is a trusted Windows machine on a private network.

WAN is your responsibility

Internet or cross-site exposure is possible, but securing it is up to you.

Single-user auth

Includes single-user auth without TLS to keep it simple.
