Questions & Answers

As answered by people managing Project Euler and BreedTools.app.

What makes your product unique?

BreedTools.app's answer:

BreedTools is the only free breeding management PWA that covers the full breeding lifecycle — from heat cycle and progesterone tracking to live whelping logs, Volhard temperament testing with automatic buyer-puppy matching, digital contracts, and a complete stud owner module with frozen semen inventory. It works offline, requires no app download, and runs on any device instantly.

Why should a person choose your product over its competitors?

BreedTools.app's answer:

BreedTools is free where competitors charge, more feature-complete than anything at its price point, and works offline without an app install. It includes features competitors don't offer at any price — Volhard temperament testing with buyer matching, frozen semen inventory tracking, semen analysis records, verified stud service reviews, and a full 7-stage buyer CRM. Pro is $9/month versus $10-12/month for less capable alternatives.

How would you describe the primary audience of your product?

BreedTools.app's answer:

Serious hobby and professional dog breeders — AKC registered breeders, kennel owners, and stud dog owners who manage multiple dogs, litters, and buyers and need more than a spreadsheet. Also serves breeders entering their first litter who want a professional setup from day one.

What's the story behind your product?

BreedTools.app's answer:

BreedTools was built by a solo founder who saw that existing breeder software was either too expensive, too basic, or too clunky for how real breeders work. Starting with a free tools site at breedtools.com, the platform expanded into a full PWA so breeders could manage their entire program — from first heat cycle to puppy go-home day — in one place, free, on any device.

Which are the primary technologies used for building your product?

BreedTools.app's answer:

Next.js, React, Supabase (PostgreSQL), Stripe, Resend, Vercel, Progressive Web App (service worker with offline caching and push notifications)

Who are some of the biggest customers of your product?

BreedTools.app's answer:

  • Independent AKC registered dog breeders
  • Multi-breed kennel owners
  • Stud dog owners managing service requests
