Built for Crested Gecko Breeders, Ball Python Breeders, and Beyond

ReptiDex was built by an active crested gecko breeder. The pedigree app, breeding records, and growth tracker features were designed around how crested gecko programs actually run: seasonal pairings, clutch-by-clutch records, morph documentation, and buyers who expect lineage paperwork. Those same tools work for ball python breeders, leopard gecko breeders, corn snake breeders, and anyone keeping serious reptile breeding records. The species list includes 137+ species with full care guides built in.

Why Reptile Breeders & Keepers Choose ReptiDex

Four things that matter to breeders.

Built by a breeder

Not a software company that discovered reptiles. Dusty Mumphrey is an active crested gecko breeder who runs Geckistry. He built ReptiDex because nothing else met the standard he needed for his own program.

Records follow the animal

Transfer an animal to a buyer and the full history goes with it: pedigree, health records, weight trends. The buyer gets confidence. You get credibility.

QR codes on every cage

Print a code, stick it on the tub. Scan it at a show. Hand it to a buyer. Instant access to the live record, no app required on their end.

No per-animal fees. Ever.

Simple flat-rate pricing. Free for up to 10 animals. Unlimited animals on Pro for $4.99/month. Your collection grows without the bill growing with it.

Dusty Mumphrey, founder of ReptiDex

Built by

Dusty Mumphrey

Active crested gecko breeder. Runs Geckistry.

I built ReptiDex because nothing else met the standard I needed for my own breeding program. After 9+ years as a senior software engineer across fintech, healthcare, and government, I had the tools to build it right. So I did.

I use ReptiDex daily to manage my own crested gecko collection at Geckistry. When something is clunky in a real breeding scenario, I feel it immediately and it gets fixed. That's why the app keeps improving. Not from a roadmap. From actually using it.

Can I transfer animals to buyers with their records?
Yes. ReptiDex includes an animal transfer feature that lets you send an animal to a buyer's ReptiDex account with the full record history attached. The buyer gets the pedigree, health records, weight trends, and morph documentation. Records follow the animal, not just the breeder.
