Design system for Activepieces (open-source AI automation platform, "open source replacement for Zapier"). Use whenever designing, mocking, or building UI for Activepieces — the web app (flow builder, runs, connections, dashboard), docs, or marketing surfaces. Provides brand purple `#8142E3`, Inter type ramp with `sm` (14px) as body default, Tailwind neutrals, Lucide icons, Shadcn/Radix primitive conventions, the signature dotted-canvas builder background, and a recreated web UI kit.

Activepieces Design System

You are designing for Activepieces — an open-source AI automation platform where users assemble triggers + actions from 280+ "pieces" into automated flows. Every piece doubles as an MCP server.

Read README.md in this folder first — it is the canonical reference. This file is a fast-loading summary for agent use.

Inventory

README.md — full spec (content fundamentals, visual foundations, iconography, caveats). Read first.
colors_and_type.css — CSS tokens (colors, fonts, radii, shadows, spacing, type ramp). Import in every HTML file.
fonts/ — Inter 400/500/600/700/800 + Sentient-Variable.woff2 (display alt, not used in app).
assets/logo.svg — brand mark. Purple #8142E3.
assets/ — piece-tile SVGs (Shopify, Airtable, Google, OpenAI, Slack, Gmail) + MCP/code glyphs.
preview/ — ~700px-wide design-system cards (type, color, spacing, components).
ui_kits/web/ — high-fidelity recreation of the Activepieces web app. Entry ui_kits/web/index.html. Form-controls showcase at ui_kits/web/forms.html. Modular JSX via Babel standalone. Screens: Flows dashboard, Builder (dotted canvas + step panel), Runs table, Connections list, Ask AI chat overlay (Lottie-animated "thinking" loader at assets/ai-loader.lottie.json). Supports light + dark mode via .dark class on <html> — toggle lives in the sidebar footer.
insights/ — Interactive Insights page. Entry insights/Insights.html. Composes the ui_kits/web/ shell (Sidebar, TopBar, Primitives, Overlays) and adds chart primitives in InsightsCharts.jsx: Sparkline, LineChart (multi-series + hover crosshair + tooltip), BarChart (stacked/grouped), Donut, Heatmap (days × hours). Page-scoped styles in insights.css define the ins-* class vocabulary (stat cards, AI summary card, quota meter, flow/error/team rows, piece grid, narrative hero). Two layout variations — Classic dashboard (hero stats + chart + donut + quota + top flows/errors + heatmap + team + live feed) and Editorial (dark narrative hero that tells the week's story + 3 highlight cards + heatmap/feed). Time range picker (24h/7d/30d/90d), compare-to-previous toggle, scope tabs (Workspace/Flow/Piece/Teammate), clickable stat cards, hover tooltips. Tweaks: layout (Classic ↔ Editorial), chart style (line/bar), AI summary on/off, density. Respects light/dark toggle.

Component inventory (`ui_kits/web/`)

Primitives.jsx — form & content building blocks: Button (default / secondary / outline / ghost / destructive / link; sizes xs / sm / default / lg / icon / icon-sm / icon-lg), Badge (default / secondary / outline / destructive / success / warning, optional dot), Input (with optional left icon, thin 32px variant), Textarea (auto-grows 1–5 rows), Label (supports required asterisk), Checkbox (supports checked="indeterminate"), Switch (optional checked/unchecked icons), RadioGroup + RadioGroupItem, Slider (single-thumb, 0..100 by default), Progress (0..100), Skeleton, Avatar, Kbd, Alert (default / primary / warning / destructive / success, with icon + title), Tabs + TabsList + TabsTrigger + TabsContent (default / pills / underline), Separator (horizontal / vertical).
Overlays.jsx — portal-based floating surfaces, all with Esc + outside-click dismiss: Popover (anchored, placement + align + offset), DropdownMenu (items support icon, shortcut, destructive, separator, disabled), Modal (sizes sm / md / lg, title + description + footer, black/50 backdrop, no blur), Tooltip (400ms delay, 120ms fade), ToastProvider + useToast() + ToastHost (bottom-right stack; .toast / .success / .error / .warning / .info).
Screen views — Sidebar.jsx, TopBar.jsx, FlowsView.jsx, BuilderView.jsx, RunsView.jsx, ConnectionsView.jsx, AskAIView.jsx, Icons.jsx.
Styling — single app.css defines the ap-* class vocabulary and light/dark tokens. No build step.

Hard rules (never violate)

Primary is purple hsl(257 74% 57%) / #8142E3 — the shipping value from packages/web/src/styles.css. Not the #9747FF swatch some Figma files show. Primary stays purple in dark mode too (brand continuity) — use .dark.blue-primary to opt back into the repo's blue-in-dark behaviour.
Body text is 14px (text-sm), not 16. Activepieces feels dense and tool-like. Headings use -0.01em to -0.02em tracking.
Sentence case everywhere: headings, buttons, menu items, page titles. Proper nouns only for feature names (Flows, Runs, Pieces, MCP, Agents, Connections).
Lucide icons only, 1.5–2px stroke, rounded caps. Default size 16 (size-4). Icon + text → gap-2 (8px). No emoji in the product UI. No Unicode glyphs (✓ × ←) — always a Lucide component.
Borders are 1px, color neutral-200 (light) / white/14 (dark). Never thicker. (Note: repo ships white/10 in dark — we bump to 14% so dividers stay readable against neutral-900 surfaces.)
No negative margins. Use gap-*, p-*, space-*. Explicitly banned in the repo's AGENTS.md.
Cards: white fill, 1px border, radius-lg (10px), NO shadow by default. Shadows only on floating surfaces (popovers, menus, dialogs).
Main content is a floating card: the sidebar blends with the outer shell (neutral-50 in light, neutral-950 in dark); the content area sits inside with radius-xl (12px), 1px border, shadow-xs, and 8px inset from the viewport edges. Matches the shipping app layout.
Builder canvas has the dotted look — background #FBFBFB (light) / #171717 (dark), radial-gradient dots #b2b2b2 1px at 16px 16px. This is signature.
Hover states darken only — primary buttons go to /90, secondary /80, ghost bg-gray-300/30. No scale, no translate, no elevation change on hover or press.
Focus-visible is a 3px ring at ring-color/50 — accessibility-first, very visible.
Disabled: opacity: 0.5; pointer-events: none. No greyed-out variant.
cn() from @/lib/utils is mandatory for className composition in production-style code. Use design-token classes (bg-primary, text-muted-foreground, border-border, rounded-md), never raw hex.

Voice & copy

Matter-of-fact, second-person, verb-first. No "Click here". No "Please". No hype.

Buttons: "New flow", "Publish", "Connect", "Test step", "Save", "Run"
Empty states: state the fact, then the action. "No flows yet. Create your first flow to start automating."
Do: "Your flow is live.", "Add a step", "Connect your Google account"
Don't: "Awesome! 🎉 Your flow is now live!", "Click here to add a step", "Please authorize Google"

Type ramp (Inter)

Token	Size	Usage
`xs`	12px	metadata, badges
`sm`	14px	body default, buttons, inputs
`base`	16px	larger body
`lg`	18px	card titles
`xl`	20px	section titles
`2xl`	24px	page titles
`3xl`	28px	display (repo overrides from 30)
`4xl`	32px	display (repo overrides from 36)

Spacing / radius / shadow

Gap scale: 4, 8, 12, 16, 24, 32, 48, 64 (base 4px).
Radii: xs 2 / sm 6 / md 8 / lg 10 / xl 12. Inputs & buttons = md. Cards & dialogs = lg.
Shadows: sm 0 1px 3px rgba(0,0,0,0.06) (cards that lift), md 0 10px 15px -3px rgba(0,0,0,0.08) (menus). No colored shadows except the add-step button: box-shadow: 0 0 0 6px var(--primary-100).

Button variants

default (purple), secondary (near-black), outline (white + border), ghost (transparent), destructive (rose), link (underlined purple). Sizes: xs 24 / sm 30 / default 36 / lg 40 (height in px) + icon / icon-sm / icon-lg (square). Icon-only buttons: square with radius-md.

Form controls (ships in `Primitives.jsx`)

Input 36px default, 32px thin; supports left icon.
Textarea auto-grows 1–5 rows.
Checkbox supports checked="indeterminate" (shows Minus glyph).
Switch 36×20px track, 20px thumb translates on check.
RadioGroup / RadioGroupItem with context-driven selection.
Slider single-thumb, filled track in primary.
Progress value 0..100, indicator translates.
Alert default / primary / warning / destructive / success with optional icon + title.
Tabs default (boxed), pills, underline — use pills for segmented controls, underline for page-level nav.
All controls respect the global focus-visible ring (3px ring/50) and the opacity-50 / pointer-events-none disabled pattern.

Animation

Default 200ms, hover 150ms. Custom ease: cubic-bezier(0.35, 0, 0.25, 1) (--ease-expand-out).
No bounces, no springs, no pop-scale. Everything glides.

Iconography

<!-- Load Lucide via CDN when building HTML prototypes -->
<script src="https://unpkg.com/lucide@latest/dist/umd/lucide.min.js"></script>

Or inline SVGs from https://lucide.dev. Piece/integration icons: copy the real SVG from packages/web/src/assets/img/piece/ — do not redraw. Piece tile is 38–48px rounded-square with an 8% tinted background of the piece's brand color.

Surfaces & layout

Fixed 260px left sidebar, fluid content. Brand + workspace switcher top-left, user pill bottom-left, theme toggle (☀️/🌙) just above Settings.
The content area is a floating card — 8px inset, radius-xl, 1px border, shadow-xs. Sidebar blends with the outer shell.
Top bar only appears inside the builder (flow name + Test/Publish). Other screens use a page header with title + subtitle + actions.
Max content width ~1400px; dense tables may break out wider.
Dialogs: radius-lg, white, shadow-md, black/50 overlay, no backdrop-blur.
Ask AI overlay: centered sheet, 520px wide, conversational. Uses the Lottie loader (assets/ai-loader.lottie.json) while awaiting a response.

Dark mode

Toggle via .dark on <html>. Persist with localStorage['ap-theme'].
Surfaces: outer shell neutral-950, floating card neutral-900, popovers/muted neutral-800, accent neutral-700.
Primary stays purple (hsl(257 74% 57%)) — brand continuity. Opt back into the repo's blue-in-dark with .dark.blue-primary.
Semantics lift from -500 → -400 for legibility on dark backgrounds (success hsl(160 60% 52%), destructive hsl(351 95% 72%), warning hsl(43 97% 56%)).
Dividers: hsla(0, 0%, 100%, 0.14) — 14% white, bumped from the repo's 10% so borders stay readable against neutral-900.

When to use the UI kit vs. build fresh

Use ui_kits/web/ as your starting point for any web-app screen (Flows list, Builder, Runs, Connections). Copy components, don't re-derive. It uses vanilla React + Babel standalone and a single app.css — no build step.
Tweak-compose: match the CSS class vocabulary (ap-page, ap-topbar, ap-btn, ap-badge, ap-side-item, ap-step, ap-canvas, ap-table, ap-trow).
For production React code targeting the real repo: write Tailwind v4 + Shadcn components and use cn(). The CSS variables in colors_and_type.css mirror the repo's :root tokens so values stay consistent.

Known gotchas

Figma file shows primary as #9747FF. Ignore it. Shipping primary is #8142E3 (from packages/web/src/styles.css and the logo).
The repo's dark mode shifts primary to blue. This system keeps primary purple in both modes for brand consistency; document the blue variant only if the user explicitly asks for dark-mode fidelity.
Sentient-Variable.woff2 is an optional display/marketing font — not used in shipping product UI. Only use if explicitly doing branding/marketing exploration.
The Pro-Blocks Figma pages (Landing, Application, etc.) are Shadcn stock templates, not Activepieces marketing. Use as Shadcn pattern reference only.
packages/web is the only shipping UI surface in the repo. There is no marketing-site code to reference.

Starting a new design

Read README.md for depth.
Import colors_and_type.css in your HTML.
Load Inter (already in fonts/) and Lucide via CDN.
If building a web-app screen: open ui_kits/web/index.html, copy the relevant component file(s), and compose.
Use sentence case, 14px body, 1px borders, purple #8142E3 only for primary action + brand. Nothing else.
