Boxy: a square-cornered design system

StartupLaunched September 2026

The Story

A design system for AI coding agents. Square corners, 1px borders, a mostly gray palette, and a linter that fails the build when the agent breaks a rule.

BOXY Overview Tokens Components Patterns mode blueprint den comfortable light 01 / A design system for agents

Boxy gives your coding agent a design system with no border radius, 1px borders and a mostly gray palette. It also ships a linter, so when the agent slips back into rounded cards and soft shadows, the build fails.

MIT · zero dependencies · 18 reference docs · 15 lint rules

Agents treat most style guides as suggestions. A few prompts in, the rounded cards and soft shadows are back. Boxy writes its rules as hard constraints, and the eighth box explains how they get checked.
