Cactusware has developed sports league scheduling software since 1998. Its product, Diamond Scheduler, generates full-season schedules for baseball, softball, basketball, football, hockey, and soccer leagues — the work that otherwise falls to a league's volunteer scheduler. Valley leagues have their own entry point through the company's McAllen page.
Diamond Scheduler builds a league's season schedule from its teams, divisions, and constraints. A first schedule takes minutes to generate. Leagues and divisions are unlimited; a division holds up to 50 teams, with the cap lifted on the Elite plan. The software runs on the web and as a desktop application, with the desktop version carrying the more advanced scheduling algorithms.
Bracket play is included, in single- and double-elimination formats, alongside round-robin, practice, and playoff schedules. Constraint settings cover minimum days of rest, maximum games per day and per week, maximum travel distance, venue prioritization, doubleheader scheduling, and prevention of coach conflicts.
Diamond Scheduler connects through DirectLink to RAMP Interactive, League Athletics, SportsEngine, Squad Fusion, and TeamSnap. The SportsEngine integration is bidirectional: league information is pulled from a connected account, and finished schedules are pushed back. League data can also be loaded by CSV upload, and finished schedules export as CSV files and in Google Calendar, iCal, and Microsoft Outlook formats. A season built in the desktop application transfers to the web version through a JSON export.
A free trial is available without a credit card; free users see partial schedules until a paid plan unlocks full ones. Leagues can evaluate the software through the trial before committing to a plan.
