TAP. TRACK. THRIVE.

Husbandry.Pro is a multi-species husbandry platform covering reptiles, inverts, amphibians, mammals, birds and fish. KeeperOS is reptile-first and room-first, with unlimited animals on every tier including Free, and built so keeping and breeding are the same app.
Husbandry.Pro is a real company with a real product: two live editions, native iOS and Android apps, a marketplace and an institution tier. If you keep reptiles, inverts, amphibians, birds and fish and want one login across all of them, it is the honest answer and this page will not pretend otherwise.
KeeperOS is the opposite bet. Everything that makes it good is a thing you can only build by not serving aviaries and fish rooms: a room you lay out the way it physically sits, feeder stock joined to real feeding demand, species care defaults that actually differ by species, and a genetics engine that resolves the morph names a breeder sells under.
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 | Husbandry.Pro | |
|---|---|---|
| Price for an uncapped collection | $6/mo for unlimited animals and multiple rooms. $15/mo adds the full breeding operation. Annual is two months free. | Published tiers run $4/mo (50 animals), $9/mo (200), $18/mo (500) and $39/mo (unlimited), with higher institution pricing above that. |
| Animal caps | No animal cap on any tier — Free included. Free covers unlimited animals, rooms and racks with full care logging; the $6 KeeperOS Pro tier adds collection-level tools. | Every tier below the top one carries a stated animal cap; the free tier is 5 animals and ad-supported. |
| How you log care | Room-first. You tap the enclosure or tub in front of you on a visual map of your actual room, and the animal, its schedule, its history, its feeder and its scent are already attached to that spot. Session rounds let you work a rack in one pass. | Record-first. Their current edition has an Enclosures workspace covering racks, cages, groups and habitats, a holding area for unplaced animals, and a per-rack grid view. Their stated positioning is breadth across animal classes rather than a layout of one physical room. |
| Feeder stock | An append-only stock ledger joined to real feeding demand, restock by packs with per-unit cost, and a 120-day burn-down with a projected run-out date that includes unplaced animals and expected clutch demand. | A feeder list with name, size, supplier, cost and quantity. |
| Genetics | For western hognose: 319 resolved morph names with alias handling, pairing odds on a project, expected-versus-actual scoring on a clutch, and proven-het discovery. Other species get full care, feeding, clutch and incubation tracking — the morph engine covers western hognose only today. | A genetic calculator with per-species trait lists and pairing odds, available across their species range. |
| Ads | None, on any tier, ever. | Their free tier is ad-supported by their own description. |

For tracking a collection of any size, KeeperOS Free is cheaper by definition: it has no animal cap at all, and it carries no ads. Their tiers are capped by animal count, so growing past a cap means paying more; a KeeperOS keeper never hits one. Our $6 KeeperOS Pro tier is priced against their $4 entry tier and buys collection-level tools — Care Profiles, Calendar, Insights, feeder forecasting — rather than a higher animal allowance.
Yes — CSV import is free for every account, and the free analyzer at /analyze previews your file in the browser before you even sign up. Full activity-history import — meal-by-meal feeding logs and weights — is not available yet, so plan on your animals arriving with their details, a starting weight and a last-fed date rather than their whole back catalog of feedings.
For western hognose, KeeperOS goes deeper: resolved morph names, pairing odds, expected-versus-actual clutch scoring and proven-het discovery, with incubation temperature tracked over time. For breeding across many species, or if you need multi-seat access and invoicing, Husbandry.Pro covers ground we do not.
The demo needs no signup. The free tier needs no card, and we don't sell your data.
