Use official OpenCode web for free
Run opencode web on your own computer when that machine can stay awake and reachable. It starts on localhost by default; set a server password before allowing network access.
▍ OpenCode on phone
OpenCode on your phone.
Use official OpenCode web on a computer you keep online, or return to a hosted OpenCode terminal after your laptop sleeps.
- Official web path is free
- Hosted terminal from €6/month
- iPhone and Android browsers

What changes
The terminal becomes a place you return to.
Use a hosted terminal when the laptop can sleep
Terminalbox runs the OpenCode TUI inside a persistent Linux workspace. Reopen the browser terminal from another device and attach to the same tmux-backed session.
Use a VPS when you need server control
Choose your own VPS when you need root, custom ports, a public OpenCode web URL, or control over the firewall and reverse proxy. Terminalbox intentionally does not provide those capabilities.
How it works
From sign-in to a persistent session.
- 01
Decide which machine owns the project
Keep the project on your computer for official OpenCode web, move it to a server you manage for SSH or native web access, or clone it into a Terminalbox workspace for a managed terminal.
- 02
Connect OpenCode to your provider
Authenticate the model provider on the execution host. OpenCode provider access, subscriptions, API usage, and model limits stay separate from Terminalbox hosting.
- 03
Leave and resume from the phone
With the DIY path, the computer, OpenCode process, and network route must remain available. With Terminalbox, the paid workspace and tmux session continue after the laptop disconnects.
Before you start
Questions worth answering.
Can I use OpenCode from an iPhone or Android phone?
Yes. OpenCode has an official browser interface, and its TUI can also be reached through a browser terminal or SSH client. In every case the code runs on the computer or server hosting the project, not on the phone browser.
What is the free way to use OpenCode on a phone?
Run the official opencode web command on a computer you control, protect network access with OPENCODE_SERVER_PASSWORD, and use a trusted private network or configured HTTPS proxy. The host must remain online.
Does Terminalbox provide OpenCode’s native mobile or web UI?
No. Terminalbox provides the actual OpenCode terminal interface inside a hosted browser terminal. It does not publish OpenCode web, add a mobile chat UI, or provide a public OpenCode server URL.
Will OpenCode keep running when my laptop sleeps?
Only if OpenCode is running somewhere else. A computer-hosted OpenCode web process stops being reachable when that computer sleeps. A paid Terminalbox workspace stays online independently of your laptop.
Are OpenCode or model-provider charges included?
No. Terminalbox charges for the persistent Linux environment. You bring supported OpenCode provider access, and its account rules, model limits, subscriptions, and API charges remain separate.
Is a normal VPS better for OpenCode remote access?
Use a VPS when you want the native OpenCode web interface on your own domain, root access, inbound SSH, custom services, or network-level control. Use Terminalbox when a managed persistent TUI and browser terminal are enough.
Persistent by default
Start here. Pick it up anywhere.
Plans start at €6 per month for one hosted coding-agent terminal.
