See it in action

A two-minute tour of Tabiya.

Tabiya is a chess database program designed to help you get better at chess. Here is the board, the notes, the engine, and the Gigabase working together.

Opening Explorer

See what strong players actually play.

Tabiya's Opening Explorer is built only from games where both players were rated 2400 or above. Every move frequency and result you see comes from master-level play, not diluted by the rest of the archive.

Build your repertoire from real statistics, then let the engine check your own games against it.

What Tabiya actually is
ta·bi·ya noun a standard position, reached by known opening moves, where established theory ends and original play begins.

A database that keeps working after you buy it.

Buying Tabiya gets you the full application — position search, game management, engine analysis, all of it — plus your starting Gigabase archive. From there, an ongoing subscription keeps things current: new games added every month, and the software itself keeps getting better too.

The database underneath is built on Lumbra's Gigabase, licensed and imported directly — not scraped, not reassembled from fragments.

Your engine, your terms
Any UCI-compatible engine — Stockfish by default. Line count, think time, and analysis depth are all yours to set.
Keeps getting better
Buy Tabiya once, then $7/month or $60/year keeps it current — roughly 25,000 new games added to your archive every month, with the software itself continuing to improve alongside it.
