Design token platform
Design systems that
ship at startup speed.
The fastest way to create, version, and sync design tokens across your entire team. Studio, Figma, and code — unified. Branches, reviews, themes, and releases designed for how you actually work.
Why designers love Particles
Everything you need to ship a design system your team will love
Studio
Ship tokens, not spreadsheets
Ditch the Google Sheet and Figma chaos. Create, edit, and browse tokens in a purpose-built editor — colour swatches, spacing scales, typography bundles. Pick a primitive or reference a semantic alias in one click.
Branching
Experiment without fear
Branch your token set like you branch code. Iterate safely, then open a review request with live colour swatches. Your team sees exactly what changed before anything touches production.
Themes
One token set, infinite brands
Dark mode, Brand A, Brand B, white-label — each theme overrides only what differs. Everything else inherits automatically. Switch themes in a click. Add a new brand in minutes, not days.
Playground
NewSee your theme before you ship it
Tweak primary, body, radius, and shadows in a side panel and watch a real Mail, Dashboard, and Cards preview update live. Pick from existing tokens, rename slots into your own vocabulary, or generate a full type scale with one wizard. Dry-run every write — never break a token you didn't mean to.
Color Wizard
NewA full palette from one hex.
Type a hex, pick an algorithm — OKLCH, HSL, tint-shade, alpha-blend, or curve-anchored — and watch a complete Tailwind shade scale appear in real time. Compare methods side by side. Save all eleven shades as primitive tokens in one click. No spreadsheet. No guesswork.
Text Wizard
NewA type scale in seconds.
Pick a base size and a modular ratio — minor third, perfect fourth, golden — and a full typography scale materialises with live previews. Tune line-height and tracking per step. Save the whole scale as composition tokens, ready for headings, body, and caption.
Shadow Wizard
NewElevation, properly layered.
Build single multi-layer shadows or an entire elevation scale from xs to 2xl. Reference a color token for the shadow tint so dark mode and rebrands cascade automatically. Live previews on light and dark surfaces, side by side.
Animation Wizard
NewMotion that feels alive.
Generate durations, easings, and ready-made compositions with real-time previews — duration bars filling at true speed, easing dots tracing their curves. Replay any animation in one click. Ship motion tokens your team can actually feel before they commit.
Figma sync
Figma ↔ Studio. Two-way. Live.
Push tokens to Figma as native Variables and Text Styles. Pull edits back to the platform. Each token carries a scope — restrict a colour to fills only, or a spacing token to gap only — so variables snap to exactly the right Figma properties.
Accessibility
Ship accessible, ship confident
Tag foreground/background pairs and get instant WCAG AA/AAA grades. Failing pairs surface the nearest compliant alternative. Accessibility isn't an afterthought — it's built in.
Releases
Freeze time. Ship trust.
Publish a semver-tagged snapshot of your tokens. Designers QA a specific release in Figma. Developers pin to it in CI. Roll back fearlessly — every release is immutable.
The workflow
From concept to shipped — in three steps
Style Playground
NewTheme your design system. Watch it react.
A tweakcn-style editor on the left, a real Mail / Dashboard / Cards / Tokens preview on the right. Every change you make is reflected instantly across the canvas — no commit, no PR, no waiting on a build.
Live preview
Mail, Dashboard, and Cards canvases update the instant you tweak a slot.
Pick or generate
Alias any slot to an existing token, or run the type-scale and shadow wizards.
Dry-run save
See every create, update, and conflict before you commit. Skip or override per slot.
