HR Stallion & Mare Ledger

Automatically tracks your Horse Reality stallion earnings, mare breeding history, and foal outcomes — private, no account needed.

HR Stallion & Mare Ledger is a browser extension for Horse Reality that quietly builds a breeding ledger as you browse — no manual entry, no account, no server. What it tracks automatically • Every stud fee that lands in your account, and which stallion earned it • Your stallions' foals, straight from their Offspring tab • Genetics, pedigree, conformation, and training for any horse you view — sire, dam, COI, tested colours, and more • Live pregnancy status and due dates for your mares, including the covering sire • Failed coverings, so a "no foal" outcome doesn't just disappear from the record • Any of your own horses the moment you view their page — stallions and mares alike, even coverings involving a stud you don't own What you get • A roster of your stallions with public/private fees, earnings, and a full breeding ledger per stud • A "My Mares" view scoped to horses you actually own, including pregnancy and genetics • A search box to look up any horse you've ever viewed, even before she's tied to a breeding record • Manual add/edit and a JSON import for backfilling history the extension didn't see Privacy Everything lives in your own browser's local storage. Nothing is ever sent anywhere except requests to horsereality.com itself. No account, no analytics, no backend. This is an independent fan-made tool and isn't affiliated with or endorsed by Horse Reality.
