Free Pinnacle odds tools
Browser-based calculators for the numbers behind +EV betting. No signup, no API key, and nothing you type leaves your machine.
Bankroll variance & risk of ruin simulator
Monte Carlo your staking plan before you risk real money on it. Set the edge, average odds, stake size and time frame, and get the median path, the 5–95% range, drawdown stats and risk of ruin — 2,000 to 3,000 runs, computed live in the browser.

Every tool here runs entirely client-side: the page loads once, and the math happens in your browser. There is no signup, no API key to paste, no server round trip, and nothing you enter is stored or sent anywhere. That also means they keep working even if you are offline — the trade-off is that they run on the numbers you type, not on live prices.
For live prices there is the paid side of PinnWire: a real-time Pinnacle odds API with REST snapshots, an odds-drop feed and no-vig fair prices. Use the tools to sanity-check a staking plan or an edge estimate first, then wire your bot into the feed that keeps those numbers current. The public demo key works on any REST endpoint with no signup, so you can compare the two in a couple of minutes.
