You know this feeling

Your league is
bleeding hours.

Every commissioner we talk to is running the same broken stack: a registration tool, a separate scheduler, a third app for refs, spreadsheets for payments, group texts for parents — and a personal phone that never stops buzzing.

Flag football is the fastest-growing sport in America. Olympic in 2028. Your tools were built for 2014.

Spreadsheets that fight you back
Registration in one tab, divisions in another, payments in a third. Every edit risks the whole thing.
The 200-person group text
Parents reply-all about rainouts at 6am. You're the unpaid moderator.
Ref no-shows on Saturday
No system tracks who confirmed. By the time you find out, kickoff is in 30 minutes.
"What field?" texts every Saturday
You sent the schedule three times. Half the parents still don't know which field.
Payment chase calls
15% of families pay late. You're calling them like a debt collector while running the league.
$15K a year for software you hate
SportsEngine charges per-player, slaps your branding off, and ships features twice a year.
Every league. Every Saturday.

This is who you do it for. Six million kids on the field this year.
You're the reason their season runs. We built the rest.

Patent Pending · Live Broadcast

Your league has its own
TV channel.

Every coach in your league gets the broadcast stack — live streaming, AI commentary, auto-clipping touchdowns. The grandparent in Florida watches every kid's game. You see all of it from your commissioner dashboard.

  • Multi-field live grid. Watch every game on every field, simultaneously, from one page.
  • AI play-by-play commentary. Every game sounds like ESPN. No human announcer required.
  • Touchdowns auto-clip. The moment a TD lands, the clip drops in the team's library.
  • Sponsor-ready. Local sponsors get airtime in your league's broadcast — your league keeps 80%.
Honest Comparison

vs The Old Guard.

SportsEngine and LeagueApps were built in an era before live broadcast, push notifications, and AI. You're paying $10-$15K/year for software your league has outgrown.

Every coach, ref, parent, and athlete

Real Questions, Real Answers

Everything commissioners
ask on the demo call.

No legalese, no dodging. The same answers we'd give you on a Zoom.

How long does it take to migrate from SportsEngine or LeagueApps? +
Same day for most leagues. Send us a CSV export of your roster, divisions, and schedule and we'll have your league live in Sideline Command in under an hour. On the 30-min walkthrough we'll do it in front of you. Registration, payment plans, and historical standings all carry over.
Who pays the $8.99 — the league or the parents? +
Your call. Most leagues build it into the registration fee so parents never see it as a line item — your dues just go up by $8.99. Some leagues choose to surface it as a "platform fee." Either way works. Stripe handles the collection; the platform fee is automatically deducted before the rest hits your bank account.
What if my refs don't have smartphones? +
The Referee App is a web app — works on any phone with a browser, including older Androids and basic iPhones. No download required. If a ref has zero phone, a coach or volunteer can run the scoring iPad on the sideline and the game still flows. Nobody's locked out.
Do parents need to create an account? +
Optional. Parents can watch live games, see the schedule, and get push notifications via a magic link to their phone — no account needed. If they want to RSVP to practices, message the coach, or track their kid's stats over time, they create a free Team Hub account in 10 seconds.
Do I need a Stripe account? What's the payment processing cost? +
Yes, you'll need a Stripe account — it takes 5 minutes to set up and money lands in your bank in 2 days. Stripe's standard processing fee is 2.9% + 30¢ per transaction (their rate, not ours). Sideline Command takes zero on top of that — your $8.99 per player is our entire cut.
What does live broadcast actually cost? +
Broadcast is opt-in, priced per field or per game. Hard cost is ~$3-$4 per 40-minute game (streaming + AI commentary). Most leagues bundle Friday-night coverage on their best 2-3 fields as a sponsor package — the sponsor pays for it, your league keeps 80%. Talk to us for a quote sized to your league.
What happens to my data if I cancel? +
Your data is yours, always. Cancel any time and we'll export everything — rosters, schedules, standings, stats, payment history — as CSVs you can take to any other system. No exit fees. No held-hostage tactics. We compete on the product, not on lock-in.
Can I make it look like my league's existing brand? +
Yes — fully white-labeled. Upload your logo, set your colors, point your domain. Coaches, refs, parents, and athletes see your league's brand throughout — not ours. Even the email broadcasts go out from your league name.
How do I get help when something breaks on game day? +
Game-day support is a real human, reachable by text. Most leagues never need to use it — the platform's been hardened across the entire 2026 season. If you do, we answer fast because we know your Saturday can't wait.
The Reveal

And this... is just the Platform.

Everything you've seen so far is one quarter of what we built. Three more apps come standard for every coach, ref, parent, and athlete in your league — all sharing one game state, all talking to each other in real time. That's why the leagues on Sideline Command are the most technologically advanced in flag football.
