Description

AI generated by Codex for Shai. A chess diagram editor with click-to-place pieces, eraser, board flip, coordinate labels, first-field FEN piece-placement import/export, up to 50 undo steps, SVG diagram export and JSON backups.

The hosted demo works in memory only because its sandbox disables storage. Export a JSON backup to retain edits across reloads. The delivered source supports browser-local persistence on a regular static host.

Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.

Condition

Development stage: Working prototype (seller-declared)

Seller-declared: provided by the seller, not independently verified by SellMyVibe.

  • Solo creator
  • Mainly AI-generated
  • Under one month in development
  • Tests included
  • Setup guide included
  • Demo available

What works

  • Place or erase pieces by selecting a palette item and activating a board square
  • Flip the board, toggle square coordinates, and load the standard starting arrangement
  • Import and export the FEN piece-placement field only
  • Undo up to 50 board edits within the current tab
  • Download an SVG diagram or plain-text placement and preserve JSON backups
  • JSON backup/import; hosted demo works in memory without network requests

What’s unfinished

  • Diagram editor only; no engine, legal moves, check validation, game play, or move history
  • No full six-field FEN, PGN, side-to-move, castling, en-passant, or move counters
  • SVG uses Unicode text pieces and system fonts; glyph appearance and availability vary by device
  • Undo history is not included in backups; loading a backup resets it

Documentation

Deployment setup

Test suite

Technologies

HTML5, CSS3, Vanilla JavaScript ES modules, Browser localStorage (standalone source only)

Setup requirements

Unzip source and run python3 -m http.server 8080 in the folder. Open http://localhost:8080 or deploy to a static HTTPS host. No build or API key. Node 20+ runs test.mjs. See README.md and QA.md.

Dependencies and ongoing costs

No third-party libraries, APIs, backend, external fonts, images, or paid subscriptions. Hosted demo is served by SellMyVibe. Standalone source requires a static HTTP/HTTPS host, which may be free within provider limits; paid plans, overages, and custom domains may cost extra.

Known limitations

Working prototype. Diagram editor only; no engine, legal moves, check validation, game play, or move history. No full six-field FEN, PGN, side-to-move, castling, en-passant, or move counters. SVG uses Unicode text pieces and system fonts; glyph appearance and availability vary by device. Undo history is not included in backups; loading a backup resets it. App data resets on reload in the hosted demo; export JSON backups. See the app description for standalone storage behavior. No independent security audit or broad device/browser certification.
