stoneChat

stoneChat is a small LLM web chat for Windows XP-era machines and IE6.

“a caveman peeking at modern technology”

Requirements

PHP 5.4 or newer is required. The launcher uses PHP’s built-in web server:

php -S

For Windows XP, use this PHP 5.4 build:

https://windows.php.net/downloads/releases/archives/php-5.4.45-Win32-VC9-x86.zip

stunnel is also required. It provides the HTTPS layer for old Windows systems. Install it normally, or extract the package and set [paths] stunnel in CONF.ini to its bin\stunnel.exe.

For Windows XP, use this stunnel build:

https://www.stunnel.org/archive/5.x/stunnel-5.26-installer.exe

Configuration

Copy the sample config:

CONF_SMP.INI -> CONF.ini

Then edit CONF.ini with Notepad. The file is heavily commented; the comments are meant to be read from top to bottom.

Inside stoneChat, the Edit config button opens the same configuration page. On Windows it first asks Notepad to open CONF.ini. Save the file there, return to stoneChat, then click Reload config. If Notepad cannot be started from PHP, the page still shows a plain web editor fallback.

Important sections:

Section	Purpose
[auth]	Brute-force lockout and session cookie name
[User NAME]	Login user, password, and rights
[Model NAME]	One complete usable LLM model unit
[ui]	Page title, fallback language, theme, editor flag

Users

The default administrator user:

[User Admin]
password = admin123
active = true
can_edit_config = true
excluded_models =
default_lang = en
send_shortcut = enter

The default guest user:

[User Guest]
password = guestpass
active = true
can_edit_config = false
excluded_models =
default_lang = en
send_shortcut = shift_enter

The name after User is the display name shown on the page. It does not decide rights. Rights are read directly from that user’s own configuration items:

Item	Meaning
password	The password typed on the login page
active	true can log in, false is disabled
can_edit_config	May open the CONF.ini editor from chat
excluded_models	Empty for all models, or a deny list
default_lang	Language selected after this user logs in
send_shortcut	Enter behavior for this user

For example:

excluded_models = GPT55

User-bound behavior checklist:

• [X] Password selects the user.
• [X] Rights are read from that user’s own section.
• [X] Language is selected from default_lang after login.
• [X] Enter / Shift+Enter behavior is selected from send_shortcut.

send_shortcut = enter
  Enter       -> send
  Shift+Enter -> new line

send_shortcut = shift_enter
  Shift+Enter -> send
  Enter       -> new line

Models

There is no separate Provider section. A model is the whole usable unit: API URL, API key, upstream model id, dispatch type, streaming setting, max token limit, and timeout all live in one [Model NAME] section.

Example:

[Model MiniMaxM3]
active = 1
label = MiniMax M3
type = openai
api_base = https://api.minimaxi.com/v1
api_key = YOUR_MINIMAX_API_KEY_HERE
model = MiniMax-M3
stream = true
max_tokens = 1024
timeout = 60

Unused sample models may remain in CONF.ini, but set them inactive:

active = 0

Inactive models are ignored by the loader and do not need real API keys.

Running

Double-click:

RUN.cmd

If CONF.ini does not exist, RUN.cmd copies it from CONF_SMP.INI.

The launcher checks:

• PHP is available.
• CONF.ini is valid.
• The port is free or can be killed.
• stunnel.exe exists.
• cacert.pem exists.
• HISTORY is writable.

After startup, open:

http://localhost:9999

Notes For Old Machines

• The main chat page is written for IE6-era JavaScript and CSS.
• The compatibility banner is written to render in IE11 and closes itself after three seconds.
• Markdown rendering is intentionally small and local; no browser package manager is required.
