LineupBud is a lineup-planning and season-tracking tool for youth baseball and softball coaches, designed to make playing time fair and reduce the work of managing team spreadsheets. It serves teams from T-ball through 13U, with features tailored to different division rules.

Coaches can create balanced defensive assignments, rotate players through positions, and track bench innings and at-bats across the season. The lineup generator accounts for attendance and pitcher selections, while pitch-count, inning-limit, and rest warnings help coaches manage pitching requirements. After each game, coaches record what was actually played so season totals remain accurate and future lineups can adjust accordingly.

LineupBud also provides a printable dugout card combining the batting order and defensive positions by inning, along with a rolling batting order that carries forward between games. Teams can import rosters by pasting a list, uploading a spreadsheet, or photographing a roster. A free plan includes one team and two games; a paid Team Pass offers 120 days of use and expanded tracking features, with an optional extension.
