Show HN: The Banana Test: coding agents grow a 3D banana plant'

The Banana Test operates in show hn launch.

Profile

I gave 5 AI coding agents one prompt: grow a banana plant through its whole life in three.js: sprout, leaves, flower, fruit, rot, then pups that restart the loop.It's deceptively simple and yet very hard to get right from procedural code: you have to write working three.js and understand how the plant is actually built; how it hangs, ages and decays. Get the biology wrong and the code renders something weird.These are agents, not bare models (Claude Code and Codex for now). They can use tools, including playwright to check their work and improve it.

As a business in show hn launch, The Banana Test is listed here with the public details available about it.

Its current recorded stage is Show HN launch.
