Anything goes: sports lines, dumb dares, office debates, who finishes a Netflix series first. If you can argue about it, you can bet on it.
Send the link
One link. No app download. No account needed to join. Your friends will actually use it.
Collect your receipts
Wins, losses, streaks — all tracked automatically. Nobody forgets, nobody weasels out.
Loved by competitive friend groups everywhere.
Don't take our word for it. Hear from real crews.
“My friend group had an ongoing side bet for 3 years. Nobody could ever remember who was actually up. SideBet ended that debate permanently.”
Marcus T.
Fantasy Football League, NYC
“My roommates and I bet on literally everything. SideBet made it official. The loser leaderboard alone is worth it.”
Priya K.
College Dorm Crew, Austin
“We made a SideBet channel in Slack. It is now the most active channel in the company.”
Jake R.
Office League, Chicago
Everything your crew needs to settle it once and for all.
Bet on literally anything
Sports, food, TV, weather, "who texts back first." If you're already arguing about it, make it official.
No app. Works everywhere.
Web-based. Any phone, tablet, or desktop. Your friends will actually click the link.
The permanent scoreboard
Leaderboards. Win streaks. Head-to-head records. Who's been talking trash with nothing to back it up? Now everyone knows.
"I never said that."
Yes you did. Every bet is permanently recorded with a paper trail. No more convenient memory loss.
Titles for winners. Shame for losers.
Custom achievements that stick. The Group Champion and The Eternal L aren't going anywhere.
Pre-loaded sports lines
NFL, Premier League, and more. Bet in seconds without typing out the odds yourself.
Not gambling. Just accountability.
SideBet doesn't touch money. Ever. No payments, no house cut, no regulatory headaches. You settle however your group always has — pizza, bragging rights, a $5 Venmo you sort out yourselves. We just make sure nobody can pretend the bet never happened.
Your group chat is overdue for a scoreboard.
Join friend groups, office crews, and dorm rooms already settling the score. Free forever. Takes 60 seconds to start.
No card required. No app download. No excuses.
