OddsGuard: The “Honey” for Sports & Prediction Markets
Stop overpaying for your plays. OddsGuard is a free browser extension that automatically finds you the best prices across 75+ sportsbooks and prediction markets while you browse.
How It Works
Like Honey at checkout — but for your lines.
Just like Honey or Capital One Shopping finds you coupons at checkout, OddsGuard works in the background of your favorite sports platforms. When you’re looking at a line, a small badge pops up to tell you if a better price exists elsewhere.
Real-Time Price Overlays
No more flipping between 10 tabs. We show you the best odds directly on the page you're already on.
The "Fair Value" Check
Our EV (Expected Value) engine calculates the "true" market price so you can spot when a site is overcharging you.
Know Your Savings
We quantify exactly how much more you're winning by choosing the better price — down to the cent.
Location Smart
We only show you providers that are legal and available in your neck of the woods.
Why OddsGuard
The industry relies on information asymmetry.
Which is just a fancy way of saying they hope you don’t check the price next door. Professional tools for this cost up to $600 a month. We think that’s crazy.
To level the playing field by putting professional-grade transparency in the hands of everyday fans — for free.
Clear the air
Is this a sportsbook? No.
OddsGuard is a tool, not a bookie.
We are a 100% independent comparison platform. Think of us like Expedia or NerdWallet — but for your sports entertainment.
What we never do
- We never accept wagers.
- We never touch your funds.
- We never process betting payments.
Pricing & Privacy
Built for everyday fans, not industry insiders.
Free Forever
Our core comparison tool is completely free. We are supported by affiliate partnerships (like most of your favorite travel or shopping sites), which means it costs you nothing extra to get the better price.
Go Pro
For the power users, we offer premium features like arbitrage alerts, instant line-movement tracking, and custom EV thresholds.
Safe & Secure
Built on modern, encrypted tech, OddsGuard is a lightweight extension designed to help you make smarter, more responsible decisions.
