Hey Product Hunt 👋
I'm the maker of BetArbi — this one started as a scratch-my-own-itch tool.
I do a bit of sports arbitrage ("surebets") — betting on every outcome across bookmakers so you profit no matter the result. The maths is simple but tedious by hand, so years ago I built a little offline calculator just for me. Friends kept asking for it, so I turned it into a proper free site.
What it does:
• Surebet / Arbitrage Calculator — 2 to 15 outcomes. Enter the odds + stake, it splits the bets for an equal, guaranteed profit.
• Free Bet Calculator — turn a free bet into locked-in profit.
• Odds Converter — decimal, fractional, American & implied probability.
Everything runs in your browser. No sign-up, no account, nothing stored, no paywall. Just the tools.
I'd genuinely love feedback — what's confusing, what's missing, which betting calculators you'd want next. Thanks for checking it out 🙏
