A dev-tools brand with a cozy soul

TreeCity Labs builds open tools for building with AI. The tools are sharp, geometric, and dev-native — but the world they live in is a cozy, lo-fi forest night: a terminal glowing in a dark cabin, a warm moon, a few fireflies. Focused, but relaxed.

Talking to an agent still means typing walls of text. Context lives in five different windows. Every project needs a different set of capabilities, wired up by hand, every time. Building the missing tools around AI coding agents— that's the whole idea.

> grow your setup, branch by branch

The mark is a tree, a git branch, and a dependency graph — all at once — growing out of a >_ terminal prompt. That's the company in one image: rooted in the command line, branching out from there.
