Particles UI review
A hosted design-system platform for governed token delivery across Figma and code.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Particles UI is a hosted design-system platform for teams managing design tokens across Figma and codebases. It centralizes tokens and supports branches, review requests, visual diffs, impact analysis, WCAG contrast release gates, immutable versioned releases, themes, and audit history. Designers can work through Studio or the Figma plugin, while developers consume approved tokens through the CLI or API. It suits solo builders and teams that need controlled changes across multiple projects or brands.
The published plans show a freemium structure. Free costs $0 per project and includes one project and main branch, three free viewers, unlimited tokens, Figma pull, inspect, one theme, and CLI exports in all formats. Pro costs $19 per seat per month and adds five projects, five branches, unlimited themes and Figma variable modes, a token graph / DAG explorer, commit history, atomic revert, Figma push, and full in-plugin CRUD. Team costs $29 per editor per month and adds token requests, review, three-way merge, a WCAG release gate, webhooks to release-to-PR, MCP and agent recipes, unlimited viewer seats, design docs, and scaffolded guidelines. Business costs $79 per editor per month and adds multi-level Foundation to Brand to Product structures, pinned module releases, conflict review, a knowledge graph explorer, granular per-project RBAC, a four-hour SLA, onboarding, and a dedicated Slack channel.
Its standout strength is the connection between token management, design-tool synchronization, code export, and governance. Figma, Tailwind, GitHub, MCP, and TypeScript are listed integrations, while webhooks and pull-request generation extend release workflows. The CLI supports multiple export formats, and the API provides another delivery path. Teams that need reviewable, accessibility-aware token releases should pick Particles UI. Teams that only need a lightweight token store may find its branching, release, and governance model broader than necessary.
