Chess Master AI - Online Chess Platform with AI & Multiplayer (PHP/MySQL)

ant your own chess website without building one from scratch? This is

the complete source code for a working online chess platform: play

against a real chess engine, challenge a friend in real time, or climb a

ranked ladder. Built on plain PHP + MySQL — no Node.js, no build

pipeline, and no monthly AI API bill, because the chess engine runs

right in the visitor's own browser.

WHAT YOU GET

• The full application source code (not a half-finished template), the
• database schema plus starter data, a web-based installer (upload, fill a
• form, done), ready-to-import demo data so the site looks populated from
• day one, and complete HTML documentation you can open straight in a

browser.

WHY THIS ONE

• The AI is free to run forever — no API bill, since it runs in the

  buyer's own browser, not your server

• No Node.js, no WebSocket server, no expensive VPS required — runs on

  the cheapest PHP shared hosting

• Clean, readable custom MVC code, not a heavyweight framework with

  hundreds of dependencies

• A guided web installer — upload, fill a form, live in minutes
• Ships with demo data — looks like a real, active site immediately,

  not an empty database

TECH SPEC

• Backend: PHP 8.0+, lightweight custom MVC, no Composer/heavy

  framework

• Database: MySQL 5.7+ / MariaDB 10.3+, PDO with prepared statements
• Frontend: vanilla JavaScript — no React/Vue, no build step
• AI engine: Stockfish, compiled to WebAssembly, runs in a Web Worker
• Chess rules/notation: chess.js
• Multiplayer sync: AJAX polling, not WebSockets — deliberate, so it

  runs on ordinary shared hosting

• Admin UI: AdminLTE 3 + Bootstrap 4 + Chart.js
• Every library is vendored in the source — nothing loads from an

  external CDN at runtime

SERVER REQUIREMENTS

• PHP 8.0+, with pdo_mysql, mbstring, openssl, json, and session

  extensions (on by default almost everywhere)

• MySQL 5.7+ or MariaDB 10.3+
• Apache with mod_rewrite (.htaccess included), or Nginx (sample config

  in the docs)

• No Node.js, no Composer, no build step, no cron job needed for

  anything

BEING UPFRONT ABOUT TRADE-OFFS

• Multiplayer move validation is client-side (each browser checks legal

  moves via chess.js); the server validates whose turn it is but doesn't

  independently re-run full chess legality. Fine for casual/social play

•   for a cash-prize tournament you'd want server-side validation added.
• Multiplayer sync uses polling (roughly 1-2 second delay), not

  WebSockets — a deliberate trade-off for shared-hosting compatibility

  over instant push.

Good fit for developers/agencies reselling source code, chess club or

hobby site owners, coaches wanting a private practice tool, or anyone

who wants chess functionality without building it from zero.
