RapidRoster

Turn a participant list into fair, rule-aware groups — teams, events, shifts, classrooms, and more.

Get started How it works

RapidRoster workspace showing results with Team A and Team B assignments from a sports roster — Results workspace with generated team assignments and export.

The problem

Manually building rosters is slow, and spreadsheets make the tradeoffs invisible.

Everything fights everything
Teammate requests, availability, roles, and skill balance all pull in different directions.
Rules can't be seen in cells
The sheet holds only names and numbers. The real constraints live in your head.
One change breaks three others
Move one person and you redo half the grid. Fairness becomes guesswork, and you never know what you traded off.

Why RapidRoster

RapidRoster lets organizers state tradeoffs as an explicit rule list — then finds placements that respect hard constraints and score best on the soft ones.

Import people and slots, set priorities, generate assignments, review what was traded off, and export when it feels right.
