Why a browser terminal changes everything

Normally, using Claude Code from a phone or tablet is impossible. You need a terminal, an SSH client, and a keyboard. With host4.ai, your terminal lives in the browser — any browser, any device, any screen size.

From your phone

Check on a long-running task during your commute. See if Claude finished building your app.

From a tablet

Code from the couch or a coffee shop. The terminal adapts to any screen size.

From any laptop

Borrow a friend's computer, open a browser, log in. No software to install.

The browser terminal includes mobile-optimized controls: special key buttons (Ctrl+C, ESC, TAB), paste from clipboard, zoom controls, and a dark theme that is easy on the eyes.

Browser terminal + SSH — you choose

The browser terminal is perfect for quick checks, mobile access, and when you do not have an SSH client. But you also get full SSH access on a dedicated port for when you want to use your favorite terminal or VS Code Remote.

Both methods connect to the same persistent session. Start work in the browser, continue in VS Code. Switch between devices freely.

Frequently asked questions

Can I use Claude Code from my phone?
Yes. The browser terminal works on any device with a web browser including phones and tablets. Mobile-optimized controls make it practical for quick tasks and monitoring.
Do I need to install anything?
No. Claude Code is pre-installed on the server. You access it through a web browser — no SSH client, no terminal app, no CLI installation needed.
Is the browser terminal as good as a real terminal?
It supports full terminal emulation — colors, special keys, copy/paste, resizing. For heavy development you can also use SSH. Both connect to the same persistent session.
Can I use Claude Code on an iPad?
Yes. The browser terminal works in Safari on iPad. With an external keyboard it is a surprisingly good coding experience. The special key buttons help when using the on-screen keyboard.
