EngineDescribe a feeling, get a theme — try the Studio

One spec in. A whole design system out.

Mlola derives every colour, radius, shadow and spring from a single theme spec, and proves the contrast of each pairing before it ships. The scene here is made of real components, moving on their own springs while one theme glides into the next.

Composing…

Every pixel above is a Mlola component, themed by the same tokens as the rest of this page. Open Generative UI in the docs

Mlola Pro

AI-native, down to the last token.

Chat, reasoning, tool calls, voice and usage, built on the same tokens and behaviour contract as every button. Bring any model; with Pro, each piece is yours to copy and edit.

Chat, end to end

Reasoning, tool calls, streamed answers and sources. Type to try it.

Why does Mlola solve colour in OKLCH?
The question is about contrast. OKLCH lightness is perceptual, so a solver can move text lightness until it clears 4.5:1 against its surface.
Model

Voice

An orb and a wave driven by a live audio meter.

A face for state

The Bot morphs on springs, follows your pointer, and wears your brand.

Usage, at a glance

Activity Heatmap: quantile shading, a keyboard grid, hover detail.

Mlola Pro · for agent harnesses

An IDE, assembled from components.

Files with git status, tabs, diffs and a terminal that speaks ANSI, all themed by the same tokens. The window below is nothing but library components.

npm test

One component tree. Five characters.

A theme moves type, geometry, density, depth, motion and texture together, so the same markup reads as a different product. Semantics and behaviour never change.

Built to outlast the framework of the year.

Plain CSS, owned behaviour and a contract a person or a model can read.

  • Zero runtime dependencies

    Native CSS and behaviour Mlola owns. React is one way to consume it; the stylesheet works in any stack.

  • A real theme engine

    Eight expression channels derive radius, depth, motion and type together. Themes are coherent, not palette swaps.

  • Accessible by default

    Keyboard paths, focus, reduced motion, forced colours and WCAG AA contrast are tested gates, not promises.

  • Readable by AI agents

    Every component ships a machine-readable contract and an agents.md guide, so coding agents write correct markup.

  • Copy, don’t install

    npx mlola-ui add copies the source into your project. You own every line and can change any of it.

  • Motion with physics

    Spring easings derived from each theme. Interruptible, and calm when the user asks for reduced motion.

Every card below is the live component, rendered with the theme you have selected.
