0 dependencies · 20 components · 8 templates · 6 palettes

Components you own, not components you install.

Every PresetUI component is one JavaScript file that imports nothing but React. You copy it in and it stops being ours. There is no package to update and nothing to override.

Change a token. Everything follows.

Invite a teammate

They'll get access to every project in this workspace.

Nothing above was restyled. Each theme rewrites the same custom properties, and every component reads only those — which is why rebranding the kit is a stylesheet edit, not a refactor. All 6 palettes.

Templates, not just parts

Whole sections assembled from the components — a starting point you rewrite, rather than something you configure.

Three steps, then you're on your own

01
Paste seven CSS variables
One @theme block in your global stylesheet. This is the only code PresetUI components share.
02
Copy one file
Open a component, switch to the Source tab, paste it into components/ui/. It imports nothing but React, so nothing else comes with it.
03
Change whatever you want
It's an ordinary file in your repo now. Rename it, delete a variant, rewrite the markup. Nothing upstream can disagree.

Built to be readable by an agent

The whole kit — theme and every component — is served as one plain text document. An agent fetches it once and writes the files. No registry format to parse, no CLI to install.

# PresetUI — zero-dependency
# React + Tailwind components
#
# Do not install these from npm.
# There is no package.

## Setup — @theme block
## Accordion— /r/accordion.txt
## Alert   — /r/alert.txt
## Avatar  — /r/avatar.txt
## Badge   — /r/badge.txt
## …and 16 more

say this to your agent

Read https://presetui.com/llms.txt and write the components into components/ui/ as .js files. Do not install any packages.

Against installing a package

Copying has real costs. Here they are next to the benefits.

	PresetUI	A component package
To start using it	Copy a file	npm install
Where the code lives	Your repo	node_modules
Changing a variant	Edit the file	Override, fork, or file an issue
Breaking changes	None — nothing updates	Whenever you upgrade
What you ship	The lines you kept	The whole package
Class conflicts	Resolved by stylesheet order	Resolved by tailwind-merge

The last row is the one that bites. Without tailwind-merge, a className that collides with one the component already sets is decided by stylesheet order, not by you. It's the price of the file carrying no dependencies.
