Count every legal move, then check the count.
Perft walks the tree of legal moves to a fixed depth and counts the positions at the bottom. The totals for a few standard positions are published, so a move generator either matches them or has a bug. Vizier’s is checked this way. Pick a position and count it yourself.

Assets
Logo, colors, and type.
Mark
The project’s generated logo mark. The grid gets finer with the commit count, and the cells show the split between languages. It’s redrawn as the project grows.
Palette
The colors Vizier uses across this site: one hue from its discipline’s band, plus the shades that make it work on both dark and light backgrounds.
Type
The two typefaces on the site: a sans-serif for the interface and a serif for headlines.
