OpenCode web remote setup.

Start OpenCode’s official browser interface on the smallest safe network boundary. Generate a localhost, private-network, or existing HTTPS-proxy plan without sending us a password, hostname, project path, or provider credential.

Where should the browser connect?

Browser access
Official behavior: opencode web defaults to localhost. OpenCode warns that network access should set OPENCODE_SERVER_PASSWORD; the username defaults to opencode. Verify in OpenCode’s web documentation ↗

Your OpenCode web plan.

Shell
# 1. Install or verify OpenCode
curl -fsSL https://opencode.ai/install | bash

# 2. Move into the project that OpenCode should serve
cd /path/to/your/project

# Authenticate a model provider if this host is not configured yet
opencode auth login

# 3. Start the official OpenCode web interface
opencode web --hostname 127.0.0.1 --port 4096

# Open in a browser: http://127.0.0.1:4096

# Optional: attach the terminal UI from another shell
opencode attach http://127.0.0.1:4096
Access boundary This computer only
Browser address http://127.0.0.1:4096
OpenCode password Not needed for localhost
Host requirement Online host + running OpenCode process
Before remote access

The browser is new. The security boundary is not.

01

Provider access stays on the host

Authenticate with opencode auth login. Never paste model keys into this page.

02

Set Basic Auth for network use

The generated command creates 256 random bits locally and keeps the value out of shell history.

03

Use a private route or HTTPS

A password does not encrypt raw HTTP. Use a private mesh or a TLS reverse proxy.

04

The host still does the work

Closing the browser is fine. Sleeping or powering off the OpenCode host stops access.

03 · Choose the honest host

Use OpenCode web when you want its native browser UI.

Run the official interface on your laptop when it can stay online, or on a server you already operate when you can secure the network and process. The generated plan is free because OpenCode already provides this workflow.

Practical answers

Know what is exposed before changing the bind address.

Can OpenCode run in a browser?

Yes. The official opencode web command starts OpenCode’s browser interface. It binds to 127.0.0.1 by default, so the default page is reachable only from the host computer.

How do I reach OpenCode from another device?

Bind it to 0.0.0.0 for a trusted private network, or keep it on localhost behind an HTTPS reverse proxy. Set OPENCODE_SERVER_PASSWORD before allowing any network access. Do not expose the raw HTTP port to the public internet.

Does the OpenCode host need to stay online?

Yes. The browser is a client of the OpenCode process running on the host. You can close the browser, but the host, network, and OpenCode process must remain available for remote access.

Does Terminalbox host the native OpenCode web interface?

Not currently. Terminalbox provides OpenCode’s terminal UI inside a persistent hosted browser terminal. It does not publish an OpenCode web port or claim to be the native OpenCode web interface.

Does this generator upload my password or project path?

No. The plan is assembled in your browser and generates the password with OpenSSL in your own shell. Terminalbox records only bounded page and button labels, never generated commands, passwords, paths, provider credentials, or source code.

Commands and defaults come from OpenCode’s web guide, CLI reference, and installation guide. Private-network and HTTPS guidance is a defensive deployment recommendation, not an OpenCode or Anomaly endorsement of Terminalbox.
