Are OddsGuard solutions free?

Yes. All 8 solutions listed here — the browser extension and desktop app, the iPhone, iPad and Mac app, the live odds board, 15 betting calculators, the OBS stream overlay, the Odds Ticker for websites, the embeddable widget, and RSS feeds — are free to use, with no account required. We earn a commission when a bookmaker signs up a customer we referred, which is why the price comparison itself costs nothing.

Which one should I install?

If you bet from a desktop browser, start with the browser extension — on Firefox or Safari it installs directly, and on Chrome, Edge, Brave, Opera or Vivaldi it runs through the desktop app. If you bet from your phone, install the iPhone app. If you just want to look at prices without installing anything, use the odds board on this site.

Do the products share the same odds?

Yes. Every surface reads one assembled feed, so a price shown in the browser overlay is the same price the widget renders on a publisher page and the same price the stream overlay prints on a broadcast.

What is the difference between the stream overlay, the odds ticker and the odds widget?

The stream overlay is a browser source you paste into OBS or Streamlabs — sized for a broadcast layout. The odds ticker is that same bottom bar as an iframe on a website: one URL, 90px tall, no script tag. The odds widget is a full comparison table you embed with a script or iframe, themed to your site and carrying your affiliate ID. Same prices underneath; three different places to put them.

Does OddsGuard take bets or hold money?

No. We compare prices and link you to the bookmaker, where you place the bet under their terms with your own account. We never log in to a sportsbook account and never hold a balance.

One odds feed. Eight ways to use it.

Whether you bet, stream or publish, you are reading the same live prices — assembled once, delivered on whichever surface you are actually on.

Not a screenshot. These are the prices the feed is serving this second.

This strip is the Odds Ticker, one of the solutions below — and the same feed the extension overlays, the app prices and the widget renders.

For line shoppers

You already have an account at a sportsbook. These put the rest of the market next to the price it is showing you, on whatever you bet from.

Browser Extension & Desktop App

Better prices on the book you already use

Reads the odds on the sportsbook page you are already looking at and shows, right beside each price, which other book pays more for the same bet. Firefox and Safari take it as an extension. Chrome, Edge, Brave, Opera and Vivaldi run the same overlay through the desktop app.

The comparison appears in place — no second tab, no copying a line across
Maintained against live site changes every week, not shipped and forgotten
No account, no card, no configuration before it works

Betting Calculators

15 free tools — arbitrage, EV, Kelly, vig

The maths sharp bettors run before they stake: strip the vig off a line, size a bet from your edge, price a parlay, hedge a free bet, buy a half point. Every one runs in your browser and shares the engine that ships inside our apps.

Nothing is sent to a server — the numbers never leave your browser
The same engine the extension and the iOS app compute with, so answers agree
Each tool ships with the worked explanation, not just an output box

For streamers

You are on air and your viewers are asking what the price is. This puts it on the layout you already built, without a second monitor.

Stream Overlay

Live odds on your Twitch or Kick layout

A browser source you paste into OBS or Streamlabs. Pick your matches, copy one URL, drag it where you want it — a bar along the bottom, a card above your cam, or a rail down the edge. It reshapes to whatever space you give it.

One URL into a browser source — no account, no API key, no code
Bookmakers, odds format and the responsible-gambling line follow where you stream from
Sponsored? Switch it to show only that book, same layout, one setting

For publishers and site owners

You run a site that covers sport. These give your pages live prices to show, and a reason for a reader to come back to them.

Odds Ticker

A live odds strip for your site — one iframe

The same bottom bar streamers paste into OBS, sized as an iframe for a page you own. Pick the matches, copy the URL, drop it where a ticker belongs — above the fold, under a match report, or along the footer.

One iframe — no script tag, no API key, no CMS plugin
Always 90px tall; it scales to whatever width you give it
Bookmakers and odds format follow the region you set when you build it

Odds Comparison Widget

Live odds on your site, one script tag

An embeddable comparison table for your own pages. It renders the books licensed in each visitor's jurisdiction, takes your colours, and carries your affiliate ID on every outbound click. One line of HTML, or an iframe if you prefer.

Per-league and per-country odds feeds, not one firehose you have to filter
Plain RSS — every reader, CMS and automation tool already speaks it
No key to request and no rate limit to negotiate before you can try it

The same feed under all of it

We assemble prices from every bookmaker we cover, normalize them into one set of markets, and serve that to every surface below. A price you see in the overlay is the price the widget renders and the price the stream bar prints.

Licensed where you are

Bookmakers are resolved from your country — and your state in the US — so you are never shown a price you cannot legally take.

Normalized, not scraped and dumped

Team names, market types and point lines are reconciled across books first, so the same bet really is the same bet on both sides of a comparison.

No account to read a price

Nothing on this page needs a sign-up, a card or an API key before it works. Accounts exist for settings that follow you between devices.

Not sure which one to start with?

It comes down to where you bet from. Pick that, and the rest can wait.
