Design system management tool for multi-repository component documentation

Yes. For your specific requirement, I’d put Supernova at the top of the list, with zeroheight as the strongest alternative.

The important distinction is that you don't just want a documentation site—you want a system of record + documentation + actual code-adoption measurement across repos.

Tool	Component docs	Cross-repo usage tracking	Governance	My take
Supernova	⭐⭐⭐⭐⭐	⭐⭐⭐⭐⭐	⭐⭐⭐⭐⭐	Best fit
zeroheight	⭐⭐⭐⭐⭐	⭐⭐⭐⭐⭐	⭐⭐⭐⭐	Best alternative
Storybook	⭐⭐⭐⭐	⭐⭐	⭐⭐⭐	Great component playground, weaker manager
Knapsack	⭐⭐⭐⭐	⭐⭐⭐	⭐⭐⭐⭐	Worth evaluating for code-heavy orgs
Backlight	⭐⭐⭐⭐	⭐⭐⭐	⭐⭐⭐⭐	Strong if you want a developer-centric workflow

Why I'd choose Supernova

Its newer Design System Adoption functionality is almost exactly what you're describing. You run its CLI analyzer against your codebases, and it produces a centralized dashboard showing:

• which components are actually used
• where they're used
• usage counts
• prop-level usage
• unused components/props
• adoption changes over time
• Storybook coverage

It explicitly supports tracking adoption across repositories. The analyzer runs locally and sends the usage results rather than your source code.learn.supernova.io

On the documentation side, Supernova can connect Figma, Storybook and repositories, maintain component metadata/status, and build documentation around the underlying component data rather than treating docs as a separate wiki.www.supernova.io

That combination is compelling because you can answer questions like:

"We have 87 components. Which ones are actually being used, by which products, and are teams using the current API?"

rather than merely:

"Here are 87 component documentation pages."

zeroheight is very close

I'd seriously evaluate zeroheight's measurement capabilities too.

zeroheight now explicitly tracks package adoption, component usage, token usage, production usage, outdated implementations, and hardcoded values. It also supports GitHub, GitLab, Bitbucket and Azure DevOps integrations for adoption analysis.zeroheight.com+1

In fact, if documentation quality and developer-facing consumption are your primary concerns, I'd probably lean toward zeroheight. Its component documentation workflow is particularly mature around Figma + Storybook + live code.zeroheight.com

The deciding question

I'd choose based on what you want the tool to be:

Choose Supernova if:

• You want a centralized design-system management platform, not primarily a docs site.
• Cross-repo adoption analytics are a first-class requirement.
• You care about component lifecycle/status and governance.
• You want Figma → tokens/components → docs → code → adoption analytics in one ecosystem.
• You want increasingly sophisticated AI/MCP integration; Supernova now also has analytics for how AI agents consume the design system.learn.supernova.io

Choose zeroheight if:

• Your primary deliverable is an excellent design-system documentation portal.
• Storybook + Figma are already deeply established.
• You want strong production-code adoption/drift measurement without necessarily making the tool the canonical management layer.
• Your repos span GitHub/GitLab/Bitbucket/Azure DevOps.zeroheight.com+1

One caveat: Supernova's current code adoption analyzer is explicitly documented as supporting React codebases, so if your repos include iOS/Android, Vue, Angular, etc., I'd validate that before committing.learn.supernova.io

My shortlist for a real evaluation would therefore be Supernova vs. zeroheight, rather than spending much time on generic documentation tools.

If you tell me roughly (1) number of repos, (2) React/web vs. native, (3) whether you already use Storybook/Figma, and (4) whether you need self-hosting, I can narrow it down and give you a concrete Supernova vs. zeroheight vs. Knapsack comparison, including pricing and integration fit.

To document your UI components and actively monitor how they are being adopted across multiple separate code repositories, you need tools that bridge the gap between design documentation and codebase analytics.

Several dedicated design system platforms and developer tools handle this exact workflow:

Dedicated Design System Platforms (Docs + Code Tracking)

1. • Supernova
   • What it does: Supernova is an end-to-end design system management platform that handles design tokens, component documentation, and automated code delivery.
   • Adoption tracking: It features a dedicated Design System Adoption Dashboard that scans your connected code repositories to show real component usage data. It breaks down adoption by repository, shows exact file instances, tracks property (prop) usage, and even highlights unused components or props that you can safely deprecate.[learn.supernova.io](https://learn.supernova.io/latest/releases/may-2026/design-system-adoption-dashboard-aouBHXev-aouBHXev)[[2](https://www.supernova.io/adoption)](https://www.supernova.io/adoption)[[3](https://www.youtube.com/watch?v=Z_d5sR16Xao)](https://www.youtube.com/watch?v=Z_d5sR16Xao)
2. • zeroheight
   • What it does: Often considered the "Confluence for design systems," zeroheight is heavily used for maintaining design-and-code guidelines, Figma integrations, and component documentation.
   • Adoption tracking: zeroheight offers an Adoption tab powered by their @zeroheight/adoption-cli tool. You can integrate this CLI tool into your CI/CD pipelines (like GitHub Actions) to automatically scan your various product repos on every push or deployment, tracking package and component-level adoption directly inside your documentation workspace.[learn.supernova.io](https://zeroheight.com/blog/action-design-system-adoption/)[[2](https://www.supernova.io/adoption)](https://.com/blog/how-to-track-adoption-in-your-design-system/)[[3]()]()

Codebase-Specific Analytics & Developer Tools

If you already have a documentation hub (like Storybook or a custom internal site) and just need the raw multi-repo tracking layer:

1. • Omlet
   • What it does: A specialized analytics tool built strictly to measure design system adoption in production code across multiple repositories.
   • Adoption tracking: It plugs into your code ecosystems to give you quantitative visibility—answering questions about which teams are lagging, which legacy components are still lingering, and how overall adoption trends look over time without needing manual surveys.[learn.supernova.io](https://omlet.dev/blog/how-leaders-measure-design-system-adoption/)
2. Open-Source Code Scanners (DIY Approach)
   • What it does: Many engineering teams write lightweight scripts using tools like React Scanner , custom rules, or GitHub API integrations ( ) to parse ASTs (Abstract Syntax Trees) across all organizational repos.

If you want to narrow this down, tell me:

• Are your component libraries written in React, Vue, Web Components, or something else?
• Do you already have a tool you use for documentation (like Storybook or Notion ), or do you need a tool that handles both docs and tracking natively?
