League software for baseball and softball

Run the whole league from one place.

The league website, schedule, scores, registration and umpires in one system, with apps for every team and family. Built to replace HomeTeamsONLINE. Works alongside GameChanger.

The DiamondHQ league office on game day: five Sunday games, three ready, one with no field permit and no umpires, and one result waiting for approval.

Game day

Know every field is ready before first pitch.

Each game shows whether its field permit, umpire crew and both teams are set. Umpires check in at the field, and an empty spot or a no-show stands out while there's still time to fix it.

Rained out at 7 a.m.? Postpone the morning's games, review the new slots and tell teams and umpires in one pass.

The umpire game-day board: one game with both umpires checked in, another with the plate umpire not yet arrived and the base spot never assigned.

How it works

Built the way a league office works.

  • Nothing official until you approve it

    Results, schedule changes, notices and money wait for a person on your staff. Help drafts; people decide.

  • Your league owns it

    Your domain, your records and your social accounts. Payments go to the league's own account, and you can export everything.

  • Stats kept honestly

    Pitching is counted in outs, a blank box is never saved as zero, and old season totals stay apart from game-by-game lines.

  • Ready for youth leagues

    Guardians, consent and privacy settings for children are built in, alongside adult leagues.

Switching from HomeTeamsONLINE

Three steps. Nothing left behind.

  1. Step 1

    Bring your history

    Seasons, teams, standings and records you're allowed to move come over. You review them before anything is public.

  2. Step 2

    Keep your domain

    Point your league's address at DiamondHQ when you're ready. The old site runs until then.

  3. Step 3

    Keep GameChanger

    Teams keep scoring there. Imported game files become official results once you approve them.
