About Chessomy

Insight shouldn't be a limited resource.

Most chess platforms treat basic engine access like a luxury. You finish a hard-fought match, you're ready to see your accuracy, and then you hit the wall: "Daily Limit Reached. Upgrade to Diamond for unlimited review."

As a player, that felt backwards. As a developer, I knew there was a better way to build. I created Chessomy to prove that you shouldn't have to choose between your budget and your growth as a player.

The Story Behind the Project

I'm Jeromy Mobley, a self-taught developer and restaurant manager based in the Comox Valley, BC.

I didn't build Chessomy to compete with the corporate giants; I built it to solve a problem for the community. I wanted a tool that didn't "ration" insight or hide the engine behind a subscription. By focusing on efficiency and modern web tech, I've been able to create a platform that offers unlimited core analysis—at no cost to you.

How Chessomy Works (and why it's free)

We can offer unlimited analysis because we've reimagined how the work gets done.

  • •Powered by Your Device: Instead of using expensive, centralized servers, Chessomy loads Stockfish 17 directly into your browser tab using WebAssembly. Your own phone or laptop does the heavy lifting.

Chessomy is built on the shoulders of giants. We use an unmodified version of Stockfish 17, the world's most powerful open-source chess engine. Stockfish is licensed under the GPLv3, and you can find its source code at stockfishchess.org. By using WebAssembly, we bring this world-class tool directly to your browser while honoring its open-source roots.

  • •No Daily Limits: Because the analysis runs on your hardware, there are no "server costs" to pass on to you. Analyze one game or one hundred; it's always unlimited.
  • •Instant Account Sync: Enter your Chess.com or Lichess username to fetch your latest games via API instantly.
  • •Interactive Game Flow: Our visual chart allows you to tap any blunder or critical moment and jump instantly to that position on the board.
  • •Privacy-First Design: Since the engine runs locally, your games and data stay in your browser session. Your preparation is your business.

An Evolving Tool

Chessomy is a solo project, and it's constantly growing. I'm building this based on how real players actually use it. If you have an idea for a feature or find a way to make the interface even cleaner, I'd love to hear from you.

If you find Chessomy useful, the best way to support the project is to share it with a friend, your coach, or your local chess club.
