Scid vs PC is a free, open-source chess database application and graphical interface for desktop computers. It is a maintained fork of the original SCID (Shane's Chess Information Database) project, adding a more polished interface and a broader set of features while retaining the efficient native database format.

The software supports managing large game databases (millions of games), analysis with any UCI or WinBoard-compatible engine, opening statistics, position search, endgame tablebase support, and tournament management. It can import and export PGN and works with the ChessBase CBH format via conversion tools.

Scid vs PC runs on Windows, macOS, and Linux and is entirely free. It is the standard recommendation for players who want the power of dedicated database software without the cost of ChessBase, and is widely used by club players and titled players alike for preparation and game organization.
