Offline Chess System — FORKFLOW

Abstract

The Offline Chess System is a browser-based chess application that runs entirely on a local machine, allowing users to play against the Stockfish engine without an internet connection. The project combines a simple web interface, n8n for workflow orchestration, and a FastAPI backend to deliver a fast and responsive chess experience.

System Architecture

The system follows a simple four-layer architecture. The browser displays the chessboard and sends player moves to n8n, which acts as the communication bridge between the frontend and backend. The FastAPI service validates moves, manages the game state using python-chess, and communicates with Stockfish to generate the AI's response before returning the updated board to the user.

Features

The application includes move validation, adjustable AI difficulty, move history, captured pieces tracking, position evaluation, undo functionality, hint generation, PGN export, and complete offline gameplay. Its modular design also makes it easy to extend with additional features in the future.

Technology Stack

The project is built using HTML, CSS, and JavaScript for the frontend, n8n for workflow orchestration, FastAPI and python-chess for backend game logic, and Stockfish as the chess engine.

Conclusion

The Offline Chess System demonstrates how modern web technologies and workflow automation can be combined to build a lightweight, scalable, and fully offline chess application. Its modular architecture ensures smooth gameplay while providing a solid foundation for future enhancements.
