Web

ReignCode 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:

reigncode web

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

Caution

If REIGNCODE_SERVER_PASSWORD is not set, the server will be unsecured. This is fine for local use but should be set for network access.

Windows Users

For the best experience, run reigncode web from WSL rather than PowerShell. This ensures proper file system access and terminal integration.

Configuration

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

Port

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

reigncode web --port 4096

Hostname

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

reigncode web --hostname 0.0.0.0

When using 0.0.0.0, ReignCode 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:

reigncode web --mdns

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

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

reigncode web --mdns --mdns-domain myproject.local

CORS

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

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

Authentication

To protect access, set a password using the REIGNCODE_SERVER_PASSWORD environment variable:

REIGNCODE_SERVER_PASSWORD=secret reigncode web

The username defaults to reigncode but can be changed with REIGNCODE_SERVER_USERNAME.

Using the Web Interface

Once started, the web interface provides access to your ReignCode sessions.

Sessions

View and manage your sessions from the homepage. You can see active sessions and start new ones.

Server Status

Click “See Servers” to view connected servers and their status.

---

Attaching a Terminal

You can attach a terminal TUI to a running web server:

# Start the web server
reigncode web --port 4096

# In another terminal, attach the TUI
reigncode 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 reigncode.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.
