blunderDB
A backgammon blunder analysis tool: import your matches from eXtreme Gammon, GnuBG, BGBlitz and Jellyfish, store every position once, and search them by structure and by mistake.
A built-in evaluator (gammonNet) judges any position offline, and says so when it cannot — no internet connection, no external engine to install.
Free and open source (MIT), one binary, three ways to run it: desktop app, command line, headless server.
Every asset is checksummed and attestable — see the full install guide for Fedora, Arch, Flatpak, arm64 and raw binaries.
