Your design desk, minus the clutter.
Compose bundles a color palette maker, a typography lab and a wireframing whiteboard into one lightweight desktop app. No sign up, no cloud, no subscription. Open it and start designing.
Build palettes that hold together.
Pick, generate and fine tune color palettes with live contrast checks. Lock a swatch, explore harmonies around it, and export the set straight into your project.
- Generate harmonious variations from any base color
- Check contrast before you commit to a pairing
- Export as CSS variables, a hex list or an image
Find a pairing before you fall for the wrong one.
Compare display and body typefaces side by side, tune scale and spacing, and preview real paragraphs instead of a single line of placeholder text.
- Preview full type scales, not single specimens
- Pair display and body faces side by side
- Fine tune tracking, leading and weight live
Sketch the flow before you touch a pixel.
Lay out screens, connect them into flows and annotate decisions on an infinite whiteboard built for early, fast thinking.
- Drop in ready made UI shapes and components
- Connect screens into a clickable flow
- Keep sketches and notes on one infinite canvas
Everything stays on your machine.
Private by default
Your palettes, type systems and wireframes are stored on this device and never uploaded unless you choose to export or share them.
Works offline
Compose does not need a connection to run. Open it on a plane, on a train, or anywhere your signal drops.
