Hey all, long-time lurker here. I built a free tool that I've been using for my own multis and figured this community might find it useful.
The problem I kept running into: I'd build a multi on Stake or Sportsbet without really knowing if the legs were value or just random picks. Most multi builders just let you stack legs with no insight into the actual margin.
So I built one that does it differently:
- Pulls live odds across AFL, NRL, EPL, NBA, MLB, NFL, NHL and 10+ other sports
- Removes the bookmaker's vig to show you the true fair-price probability on each leg
- Auto-selects the best combination of value legs closest to your target odds (e.g. build a 5-legger around $10 odds)
- Quarter-Kelly stake calculator based on your bankroll
- Logs every multi and tracks your running P&L with a chart
- Auto-checks results every 5 minutes
It's free to use at stake-multi-builder.pages.dev — you just need a free API key from the-odds-api.com (500 free requests/month, plenty for daily use).
There's also a Pro tier at $5/month if you don't want to manage an API key — shared credit pool, email alerts when bets settle, and a Telegram bot.
Not affiliated with any bookmaker. Built for personal use and sharing here in case others find it useful. Happy to answer questions
