Emerged finds new products worth a look, daily — what’s new today
It is a free, public demonstration that a whole chess index can be nothing but compressed bitmaps, with a guide that walks through each encoding the author chose.
A chess database on the web, published on 6 October 2026 by Luka Asatiani, a software engineer and chess player. Games, players, positions and tags each get a browsable view alongside an analysis board, and a How it works guide covers the compressed bitmap structure, the encodings for games, positions, players and tags, and how a query is composed from them. The site is served by a Rust web crate and rendered in the browser. No repository or licence is linked, and the number of games indexed is not stated anywhere public, so the scale has to be judged by using it.
