Web

Using hordecode in your browser.

hordecode can run as a web application in your browser, providing the same powerful AI coding experience without needing a terminal.

Getting Started

Start the web interface by running:

horde web

This starts a local server on 127.0.0.1 with a random available port and automatically opens hordecode in your default browser.

Configuration

You can configure the web server using command line flags or in your config file.

Port

By default, hordecode picks an available port. You can specify a port:

horde web --port 4096

Hostname

By default, the server binds to 127.0.0.1 (localhost only). To make hordecode accessible on your network:

horde web --hostname 0.0.0.0

When using 0.0.0.0, hordecode will display both local and network addresses:

  Local access:       http://localhost:4096
  Network access:     http://192.168.1.100:4096

mDNS Discovery

Enable mDNS to make your server discoverable on the local network:

horde web --mdns

This automatically sets the hostname to 0.0.0.0 and advertises the server as hordecode.local.

You can customize the mDNS domain name to run multiple instances on the same network:

horde web --mdns --mdns-domain myproject.local

CORS

To allow additional domains for CORS (useful for custom frontends):

horde web --cors https://example.com

Authentication

To protect access, set a password using the HORDECODE_SERVER_PASSWORD environment variable (the legacy OPENCODE_SERVER_PASSWORD name is still accepted as a fallback):

HORDECODE_SERVER_PASSWORD=secret horde web

The username defaults to hordecode but can be changed with HORDECODE_SERVER_USERNAME.

# Start the web server
horde web --port 4096

# In another terminal, attach the TUI
horde attach http://localhost:4096

This allows you to use both the web interface and terminal simultaneously, sharing the same sessions and state.

Config File

You can also configure server settings in your hordecode.json config file:

{
  "server": {
    "port": 4096,
    "hostname": "0.0.0.0",
    "mdns": true,
    "cors": ["https://example.com"]
  }
}

Command line flags take precedence over config file settings.
