The Ensemble suite
Eleven small tools, one honest API.
One color in, a working design system out — ramps, type, spacing, shadows, and motion as one coherent object your tools and agents can read.
✶ The free tools never need an account. Pro is $4.99/mo.
The tools
Each does one job. They read each other's work.
One shared schema, one namespace per tool — no context-switching, no silos, nothing overwritten.
Harmony
OKLCH shade scales — 11-stop palettes from any seed color with perceptually uniform steps.
Duet
17 curated font pairings with modular type scales, matched to your mood and brand.
Pitch
Full-palette contrast audit — WCAG 2.1 and APCA validation with auto-fix suggestions.
Tempo
Font-aware spacing — semantic tokens that respect your type scale and base unit.
Chord
4-level shadow system — palette-tinted elevation layers, not generic gray.
Riff
7 motion presets — enter, exit, hover, focus with matched easings and durations.
Cadence
Responsive grid configs — columns, gutters, and breakpoints from one base unit.
Bridge
Dark mode generation — inverted palette, shadows, and spacing that just works.
Motif
7 component patterns — button, card, input, badge, alert, modal, nav tokens.
Score
Icon library recommendations — matched to your visual style and component needs.
Compose
Export everything — CSS custom properties, SCSS variables, Tailwind config, W3C JSON tokens.
The pipeline
Change one thing. Everything follows.
All values sync across tools automatically.
webMCP
Your agent can drive these tools.
Native webMCP support wires Ensemble straight into the machine context — deterministic calls, no scraping, no guesswork.
One API call. Complete design system.
Colors, typography, spacing, shadows, dark mode, components, icons, exports — all from a single hex code.
Pro is $4.99/mo or $39/yr. The browser tools stay free forever.
