Compare
ReptiDex is breeder-first, native on iOS today, multi-user today, and carries hognose in its genetics library — the closest overlap with what we do. KeeperOS has no animal cap on any tier including Free, logs care from a map of your room, and goes deeper on western hognose specifically.
ReptiDex is the sharpest comparison in this set and we are not going to soften it. They position as "Built by a breeder, for breeders", their tagline is "Every animal carries its whole record", and they ship things we do not: a native iOS app in the store, multi-user collections with owner, admin, member and viewer roles, five-generation printable pedigrees, and cross-collection lineage links. Their genetics library covers eight species and hognose snake is one of them. That is direct overlap with our core niche.
Where we differ is caps, and where the app puts you. Their Free tier stops at 10 animals, 100 weight records a year and 5 breeding pairs; ours has no animal, room or rack cap on any tier, Free included. And their model is record-first with QR cage cards to reach an animal, while ours is a map of your actual room that you tap. Both are real designs. The question is which matches how you work.
KeeperOS is one product across keeping and breeding. The animal you logged feedings for as a single pet keeps its whole history on the day you pair it, so growing into a breeding project is a change of tier, not a change of tool.
| KeeperOS | ReptiDex | |
|---|---|---|
| Animal and record caps | No animal cap, no room cap and no rack cap on any tier, Free included. No annual limit on weights or any other record, and no cap on breeding pairs. The tier line is which tools you get, never how many animals you own. | Free is stated as up to 10 animals, 100 weight records per year, up to 5 breeding pairs, 1 GB photo storage and single user. Unlimited animals and records begin at Pro, $4.99/month or $49.99/year with a stated 7-day free trial. |
| How you log care | A visual map of your actual room — racks, tubs and enclosures laid out where they physically sit, tapped directly. Session rounds work a whole rack in one pass with fill, water and condition tabs. | Record-first, with QR cage cards at the rack. In their words, "scan a QR at the rack, and hand buyers proof instead of promises", and buyers who scan the code see the full public record. |
| Genetics | For western hognose specifically: 319 resolved morph names with alias handling, pairing odds on a project, expected-versus-actual scoring when a clutch hatches, and proven-het discovery from real outcomes. Western hognose only today — other species get full care, feeding, clutch and incubation tracking without the morph engine. | A genetics library covering the eight species they list: Axolotl, Ball Python, Bearded Dragon, BO Boa Constrictor, Corn Snake, Crested Gecko, Hognose Snake and Leopard Gecko. Their calculator is stated as free and not requiring an account. |
| Feeder stock | An append-only stock ledger joined to the feedings you actually recorded, restock by packs with per-unit cost, a 120-day burn-down and a projected run-out date. | Not claimed in their stated feature set, so we make no claim either way. |
| Multi-user access | Single keeper. One account, one collection. BreederOS Teams is announced but NOT shipped — you cannot buy it and there are no seats or roles today. | Stated today: up to 3 users per collection on Pro, unlimited collaborators on Premium, with owner, admin, member and viewer roles. |
| Platforms | A web app you install to your home screen, built for one-handed use at the rack. | Their words: "Free on web and iOS. Android coming soon." iOS 15.1+, stated as working fully offline with auto-sync. |

Breadth versus depth. They list a genetics library across eight species with hognose among them. We do western hognose only, and go further inside it: 319 resolved morph names with alias handling, pairing odds on a project, expected-versus-actual scoring when the clutch hatches, and proven-het discovery from real outcomes. If you keep several of their eight species, their breadth is worth more than our depth.
Not today. KeeperOS is single-keeper — one account, one collection. BreederOS Teams is announced but not shipped and cannot be bought, so there are no seats or roles right now. ReptiDex states up to 3 users per collection on Pro and unlimited collaborators on Premium. If you need a second person in the app, choose them.
Theirs is stated as 10 animals, 100 weight records a year, 5 breeding pairs, 1 GB of photos and a single user. KeeperOS Free has no animal, room or rack cap and no record cap — the difference between our tiers is which tools you get, not how big your collection is. Their pricing as published September 11, 2026.
The demo needs no signup. The free tier needs no card, and we don't sell your data.
