Three White's Tree Frogs named Mango, Kiwi, and Fig

Our story

Why I built this

When I got my White's Tree Frogs, I wanted to get everything right. The research got overwhelming fast. One source said 10 gallons was fine, another insisted on 20. Screen or glass? UVB or not? Every answer conflicted.

I didn't want guesswork. I wanted to know what my frogs actually needed to thrive, and then I wanted help keeping it that way once the tank was built.

So I built Habitat Builder: a tool that turns species care requirements into a sized enclosure, a shopping list and build steps, and then helps you run it with a care schedule. It started with my frogs and now covers 11 species.

How it works

Where the numbers come from

Every species profile sets temperature, humidity, UVB and minimum size targets. Your plan is checked against them, and equipment is sized to your enclosure, not to a one-size-fits-all list.

Recommendations are math-based, not AI guesses: formulas for enclosure volume, temperature difference and UVB coverage decide the sizing.

  • Equipment manufacturersUVB output, wattage, coverage and lifespan specs.
  • Scientific literatureThermal biology, UVB zones and natural habitat research.
  • Experienced keepersPractical input from hobbyists who keep these species every day.

Our commitments

What you can count on

The planner stays free

Build plans, shopping lists and care guides are free, and always will be. No account needed to make a plan.

We don’t sell your data

Your enclosures, animals and care records are yours. See the privacy policy for the details.

Honest about how we’re paid

Premium subscriptions and some Amazon shopping links fund the project. Affiliate links cost you nothing extra, and they never change what we recommend.

We’re not vets

Habitat Builder is a strong starting point, not veterinary advice. Every animal is different, so keep learning, and if your animal seems unwell, see a reptile or amphibian specialist vet.
