Months of strategizing, yet most teams end the season empty-handed.
Most teams have no shot at a payout once playoff brackets are set. Even solid managers with unlucky injuries or bad beats get nothing.
Once a few teams fall out of contention, they stop setting lineups, answering trade requests, or even checking scores.
Sideline Props adds weekly side bets, wagers, and payout tracking—so every matchup matters, even if you’re out of the playoffs.
Weekly Side Bets
Bet on your fantasy matchup, player performances, or wild custom props, using your existing league.
Auto Tracking & Settlements
We track who owes who, automatically.
No Real-Money Transfers
Just structured, legal-friendly bet tracking.
Import Your League. Instantly sync your existing league from Sleeper or ESPN, and Sideline Props will sync the rosters.
Set Up Weekly Side Bets. Create or join bets against your league mates on things like whose QB will score more, or whose team will outperform the rest.
Track Your Winnings. See your side-bet history against every league mate and track who’s up and who’s down.
Nope! We track everything but leave the stakes up to you. You can bet whatever you want—cash, pride, punishments, or just straight-up bragging rights.
Not at all! You can challenge just one league-mate at a time or get your whole league involved. No need to beg your whole league to join.
Less than a minute. Just sync your fantasy team, and you’re ready to bet. No manual entry, no hassle.
No problem. We automatically track every bet and settle it for you. No more arguments, forgotten payouts, or sketchy IOUs.
Because group chats suck for tracking bets. Payouts get lost, and people forget who bet what after a few weeks.
Nothing! Sideline Props is completely free. No adds, no hidden locked features. Enjoy!
Sign ups for the waitlist and we'll let you know when you can try it out.
