Gecktopia
What will you create?
A breeding game built on real crested gecko genetics. Pair two animals, and what hatches is worked out from their genes.

Not one of these is a picture we drew. Every animal behind this text was built from its own genetics, in your browser, just now.

A game about what survives across generations
Gecktopia is a persistent crested gecko breeding and collection game built around inheritance, selective breeding, lineage, and discovery. Every gecko has a lasting biological and visual identity shaped by its genetics and ancestry.
Pair geckos, study the traits that appear across generations, and develop bloodlines in your own direction. Colors, patterns, structure, and other characteristics combine to produce animals with distinct identities. There is no single perfect gecko. The challenge is deciding what you want each line to become.
Built on real genetics
Which traits are inherited, how breeders report each one passing on, where they still disagree, and which pairings carry welfare concerns: it comes from published research and breeders' documented projects, each graded for how well it is supported.
Crested gecko genetics is not a solved science, so the renderer has to make choices. Where the game simplifies something, or adds a gene the research does not name, it says so in writing.
And then they pass it on

Playable now
Change genes and watch the gecko redraw. Start simple, or open every gene and set copies and strengths yourself. Share what you make with a link.
Open the builderEvery morph the renderer draws, in plain words: what it looks like, where it shows on the animal, how it is inherited, and what happens when other genes join it.
Browse the libraryWhere each pattern lives on a crested gecko, and why. The same rules the renderer follows, written for someone who has never bred a gecko.
Start learningNew morphs go live as they are drawn. What’s new lists them, and the Dev Log covers the work behind them.
See what’s newThe heart of Gecktopia
Traits are inherited across generations rather than randomly assigned.
Every gecko keeps a persistent appearance, ancestry, and individual history.
Pedigrees preserve how colors, patterns, and traits develop through a bloodline.
In development
A small group is playing these now. Join the Hatch List to hear when it opens wider.
Choose two animals and study the odds before you commit to a pairing, using the same genetics the renderer draws from.
Pedigrees that remember how a trait entered your line and how it travelled, generation by generation.
A gecko keeps its appearance, its ancestry and its history. No two are the same.
The renderer is learning the whole genetic database, morph by morph, so the range you breed toward keeps growing.
Founder tiers
Gecktopia is in development, and founder tiers are how you can help build it. Each is a single payment. What they carry is recognition, cosmetics and a small head start. None of it touches genetics. Full refund within 30 days, no reason needed.

What no founder tier buys
Gecktopia is being built by one person. The first hatch is expected in spring 2027, and the founder terms set out what happens if it never launches.
