Play my chess bot
I built this engine. It runs entirely in your browser — drag a piece to play. Fair warning: it opens by walking its king into the open. On purpose.

How it's thinking
Make a move — then watch the engine's reasoning show up here.
Wait, I'm really playing your bot?
Yep. Bongaclang is a chess engine I wrote in Python that plays on Lichess. I ported its brain to TypeScript so it runs right here in your browser — in a Web Worker, so the page never freezes while it thinks. Same evaluation, same search, same opening philosophy (it really does play 1. e4 then 2. Ke2). No server, no waiting for my bot to be online.

The real Bongaclang
The board above is a faithful TS port. Here's the actual bot, live on Lichess.
