What's a good "design system manager" tool for documenting our components and tracking their usage across different repos?

When you need a tool that handles both rich documentation and cross-repository usage/adoption tracking , the landscape usually narrows down to a couple of heavyweight platforms and a few developer-focused approaches.

Evaluating the top choices for managing documentation and tracking multi-repo code usage reveals distinct options:

1. Zeroheight (Best for Documentation + Adoption Analytics)

Zeroheight has evolved past just being a "storybook for designers". It bridges Figma, Storybook, and code repositories directly.

• How it handles documentation: It syncs with Figma and Storybook, allowing you to build clean, human-readable documentation sites with zero code.
• How it tracks cross-repo usage: Zeroheight features an Adoption Tab powered by a CLI tool. Your CI/CD pipelines or developers run the CLI to parse codebases, feeding data back into a centralized dashboard. It tells you precisely which repos are consuming which component versions, which components are dead weight, and who is lagging on updates.

2. Supernova (Best for Tokens, Metadata, and Data-Driven Pipelines)

Supernova treats a design system as structured data rather than just pages of text. It’s built for enterprise scale and multi-repo architectures.

• How it handles documentation: It integrates deeply with design tokens and component metadata, versioning your documentation right alongside your design system releases.
• How it tracks cross-repo usage: Supernova allows you to manage component statuses across platforms (React, iOS, Android) and link external references like GitHub repos and Storybook instances. While it handles the distribution side brilliantly, deep multi-repo code parsing often relies on custom static analysis scripts (like react-scanner ) feeding into their data ecosystem.

3. Storybook + Chromatic (Best for Code-First Teams)

If your engineering team is the primary driver and components live in code first, Storybook is already de facto documentation. Paired with Chromatic (built by the Storybook core team), it becomes a powerhouse.

• How it handles documentation: It’s a living documentation environment built straight from your actual production components.
• How it tracks cross-repo usage: By publishing component registries to a shared Chromatic hub or utilizing package-level dependency tracking across your organization's npm/GitHub packages, you can see visual regressions and component coverage. However, it requires a stronger engineering setup than zeroheight.

Summary Recommendation

• Choose Zeroheight if you want the easiest path to cohesive cross-team documentation and out-of-the-box CLI tracking to see which GitHub repos are importing your components.
• Choose Supernova if your biggest pain point is heavy multi-brand/multi-platform design token architecture and strict version governance.

To help narrow this down, tell me:

• Are your component libraries written in React, Vue, or multi-platform (web + mobile)?
• Do you prefer a solution that scans your GitHub repos via CI/CD , or a tool where designers/managers maintain the status manually?

If your key requirement is “document components + see which components are actually used across multiple repos,” I’d look closely at Supernova and zeroheight. They’re both now doing much more than traditional design-system documentation.

The two I’d shortlist

• supernova.io — probably the closest match to your description. It combines design-system documentation, component/token management, Storybook/Figma integration, and code adoption analytics. Its analyzer can scan repositories and show which components are used, where they’re used, prop-level usage, and how adoption changes between snapshots. The current adoption analyzer supports React.
• zeroheight.com — particularly strong if documentation and governance are the center of gravity. Its adoption tooling tracks component usage, package versions, hardcoded values/drift, and usage across repositories; it also integrates with GitHub, GitLab, Bitbucket, Storybook, Figma, and IDE/AI workflows.

| Supernova | zeroheight --- | --- | --- Component documentation | Strong | Strong Figma + Storybook | Yes | Yes Cross-repo component usage | Yes | Yes Usage over time | Yes | Yes Prop-level usage | Yes | — Package/version monitoring | Yes | Yes Detect drift/hardcoding | — | Strong Design tokens | Strong | Strong Multi-brand systems | Strong | Yes Best fit | System management + adoption analytics | Documentation + governance + adoption

Supernova's adoption dashboard is explicitly built around production-code usage, while zeroheight's measurement tooling goes further into package versions, tokens, hardcoded values, documentation engagement, and drift.

One important caveat

The phrase “across different repos” is where I'd test these tools carefully. Both aren't simply GitHub search dashboards: they run analyzers against your code and send usage data back to the platform. For example, zeroheight provides a GitHub Action that can analyze component/color usage and monitor package versions per repository. GitHub Supernova similarly uses its CLI analyzer to generate repository usage snapshots.

So if your stack is React + multiple GitHub repos, I'd put Supernova and zeroheight head-to-head in a trial, using 3–5 real repos and checking whether their component detection matches reality.

If you tell me your stack (e.g. React/TS + Storybook + GitHub, Angular, Vue, etc.) and roughly how many repos/teams you have, I can narrow this down and include Knapsack, Storybook, Backlight, and open-source options too.

When you need a tool that handles both rich documentation and cross-repo usage tracking/adoption analytics , the tool landscape generally splits into dedicated design-system platforms, developer-first component workbenches, and enterprise governance hubs.

Top options tailored to documentation and multi-repo tracking include:

• zeroheight — The industry standard for bridging design and code. It lets you pull in Figma assets, link your GitHub or GitLab repositories to render live coded components, and provides adoption/usage analytics to see how components are performing. It’s ideal if your team has a mix of designers and developers who need a unified portal.
• Supernova — Excellent for automated design token and asset synchronization. Supernova excels at translating Figma variables/tokens into production-ready code across multiple platforms and repos, and it includes robust documentation features alongside tracking capabilities for design system versioning and adoption.
• Knapsack — Built specifically for larger or enterprise teams dealing with multi-repo architectures. Knapsack combines code and design documentation in a single system, offering robust governance features, version control, and actual visibility into component consumption across different product codebases.
• Storybook (with addon ecosystem) — If your repos are already heavily TypeScript/JavaScript-based, many engineering teams bypass a traditional "manager" tool and use Storybook as the component documentation source of truth. Combined with telemetry or internal repo-scanning scripts (or tools like Chromatic), you can track how components are consumed across different packages and repositories.

To help narrow down the best fit, could you tell me:

• Are your component libraries React, Vue, Web Components , or multi-framework?
• Do you need a tool that speaks equally well to designers (Figma) and developers , or is this strictly an engineering-driven initiative?

If you need both component documentation and cross-repo usage tracking, I’d look beyond a pure docs tool. The best choice depends on how mature your design system is and how much engineering visibility you need.

Here are the strongest options:

Supernova.io Zeroheight## My shortlist for your use case

1. Supernova — best fit if adoption tracking is a requirement

Supernova is designed around connecting:

• Figma components
• design tokens
• Storybook/code components
• documentation
• usage analytics

Its adoption dashboard can analyze codebases and show things like:

• which components are used
• where they appear
• adoption trends over time
• prop-level usage patterns (for supported stacks such as React)

This is the one I’d evaluate first if your question is literally “who is using which component in which repo?”

2. zeroheight — best if documentation quality is the priority

zeroheight is excellent for:

• component guidelines
• design rationale
• usage examples
• linking Figma and Storybook artifacts
• component status tracking

It can maintain component sets that connect documentation, design files, and Storybook instances.

Where it is weaker: it’s more of a design system knowledge hub than a code adoption intelligence layer.

3. Storybook + analytics tooling — best engineering-first stack

A lot of teams use:

• Storybook for the canonical component playground
• GitHub/code search/CI checks for adoption tracking
• a docs layer on top

This gives engineers a great workflow, but you’ll build more of the governance layer yourself.

A practical architecture I see work well

For a multi-repo organization:

• Storybook → live component API, examples, visual testing
• Figma → design source
• Supernova or zeroheight → human-facing docs/governance
• CI-based component scanner → detect usage, deprecated components, migration progress

Questions I’d use to choose:

1. Do you need to answer “Which repos are still using Button v1?” automatically?

• Yes → lean Supernova.

2. Do you mainly need beautiful docs designers and engineers browse?

• Yes → zeroheight is a strong choice.

3. Are you already heavily invested in Storybook?

• Yes → keep Storybook and add a governance layer rather than replacing it.

If you have 50+ repos or multiple product teams, I’d probably start with a Supernova evaluation. If you have a smaller system (one app/team), Storybook + zeroheight is often enough.

If your key requirement is “document components centrally and understand how they’re used across multiple repos,” I’d shortlist these:

1. knapsack.cloud — best fit for your description

• Built specifically around connecting design, code, and documentation.
• Can scan code sources and automatically discover reusable components.
• Gives you a centralized view of components/patterns, their status, design connections, and code connections.
• Supports multiple frameworks and Git-based workflows.
• Particularly compelling if you have several repos/products consuming the same design system.

2. storybook.js.org + Composition — best developer-first option

• Excellent for live component documentation and API/variant examples; Autodocs can generate documentation from your stories.
• Storybook Composition lets you bring multiple Storybooks together, including across different tech stacks, which is useful for auditing components across projects.
• The downside: it's more of a component development/documentation system than a full design-system governance/asset-management platform.

3. zeroheight.com — best documentation-first option

• Strong for combining design guidance, usage rules, brand/content guidelines, and live code examples.
• It integrates with Storybook so the docs can surface actual components rather than screenshots.
• I'd favor it when the primary audience is designers/product teams, rather than engineers managing many codebases.

4. supernova.io — worth considering for a more automation-heavy system

• Stronger if tokens, code generation, and design-to-code workflows are important.
• It also has integrations/MCP capabilities for exposing design-system information to AI tooling.

My recommendation

For your specific wording, I'd start with Knapsack.

The distinction I'd make is:

One important caveat: “tracking usage across repos” can mean two different things. If you mean “show me which repos consume Button v3 and which components are deprecated/unused,” I'd specifically validate that workflow in demos. Knapsack clearly provides cross-design/code visibility and component status management, but I'd want to test your exact repo-level dependency/usage audit before buying.

If you tell me roughly how many repos, which frameworks (React/Vue/etc.), and whether Figma is part of the workflow, I can narrow this down to the best 2–3 and compare them feature-by-feature.

When you need to document components and track actual usage across multiple repositories , a single out-of-the-box tool rarely does the cross-repo code scanning natively on its own. Instead, teams typically combine a robust design system documentation platform with code-level tracking (via custom scripts, CI/CD pipelines, or specialized enterprise governance tools).

Top-tier tools fit different organizational setups:

• zeroheight
  • Core Focus: The gold standard for human-readable, beautifully branded design system documentation.
  • How it handles docs: Syncs seamlessly with Figma, Storybook, and code repos to keep design and documentation unified. Non-technical stakeholders (PMs, copywriters, QA) can easily contribute and read.
  • Multi-repo tracking: Zeroheight features adoption analytics, but for deep, granular component tracking across separate codebases , teams usually pair it with Storybook stats or custom analytics hooks rather than relying on zeroheight to parse raw GitHub repos.
• Supernova
  • Core Focus: Automated design token and asset delivery pipelines.
  • How it handles docs: Exceptional at managing component properties, documentation, and transforming design tokens out to multiple production code repositories automatically via CI/CD.
  • Multi-repo tracking: Gives you robust version control and tracking over where and how tokens/assets are delivered, making it ideal if your multi-repo problem stems from syncing design updates globally across diverse tech stacks.
• Knapsack
  • Core Focus: Enterprise-grade governance and code-backed design systems.
  • How it handles docs: Bridges the gap by letting actual production code components and documentation live in a shared platform while tying back to Git.
  • Multi-repo tracking: Because it focuses heavily on code-connected architecture, it’s better suited for large-scale enterprise structures trying to govern component usage and versioning across a fragmented ecosystem of web apps.
• Storybook + Chromatic
  • Core Focus: The developer-centric gold standard for building, testing, and isolating UI components.
  • How it handles docs: Uses MDX to document components directly alongside the code.
  • Multi-repo tracking: If your primary pain point is tracking code usage across 5+ disparate repositories, teams often write a lightweight internal script (e.g., a GitHub Action running a Babel/AST parser or grep-ing package imports across repos) and feed that data into an internal dashboard (like Metabase or Datadog) or combine it with Chromatic’s ecosystem visibility.

To help narrow down the best fit, tell me:

• What technologies/frameworks are your various repos using (React, Vue, Angular, multi-stack)?
• Do you need tracking primarily for designers to see adoption in Figma, or for engineering leads to audit code across teams?

If your key requirement is “document our design system and tell me where/how each component is actually used across repos,” I’d shortlist Supernova and zeroheight, with Knapsack as a strong alternative.

My pick: Supernova

Supernova is probably the best fit if cross-repo usage analytics is a first-class requirement.

Its 2026 Design System Adoption feature can show:

• Which components are actually used vs. unused
• Where components are used in your codebase
• Usage at the prop level
• Adoption over time via snapshots
• Component counts and adoption KPIs
• Storybook coverage

It works by running a Supernova CLI analyzer against your repositories, so you can feed usage data from multiple codebases into a centralized dashboard.

It also covers the documentation side well: Figma, Storybook, live code, tokens, assets, component health, etc.

zeroheight: excellent if documentation is the priority

zeroheight has a particularly mature documentation experience and now has design-system adoption analytics too.

Its adoption tooling can analyze component usage, color usage, and package versions across repositories through its CLI/GitHub Action.

Its component model is also nice for maintaining a lifecycle view: design ↔ documentation ↔ Storybook ↔ implementation, with component status/health tracking.

I'd choose zeroheight over Supernova if: your primary job is creating a polished, broadly consumed design-system documentation site, and usage analytics are important but secondary.

Knapsack: worth evaluating for design/code alignment

Knapsack takes a more code-centric approach. Its Code Sources can scan code locations and automatically discover reusable components, while its component/pattern management connects design, code, and documentation.

I'd look at it particularly if your team wants the tool to understand actual component implementations, rather than primarily being a documentation CMS.

Quick comparison

| Supernova | zeroheight | Knapsack --- | --- | --- | --- Component documentation | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ Cross-repo usage tracking | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐ Prop-level usage | Yes | Some analytics | More code-oriented “Where is this used?” | Yes | Yes | Yes/code-centric Storybook integration | Yes | Excellent | Yes Figma integration | Yes | Excellent | Excellent Component health/status | Yes | Excellent | Excellent Tokens/design foundations | Excellent | Excellent | Excellent Developer/code workflow | Excellent | Good | Excellent

For your exact wording, I'd start with Supernova. The differentiator is that you're not just asking for a place to document components—you want a system that can answer “Which repos/products are using Button, how often, with which props, and is adoption increasing?” That's precisely what Supernova's current adoption dashboard is designed to answer.

If you tell me roughly how many repos, which stack (React/React Native/iOS/etc.), and whether you use Figma + Storybook, I can narrow this down to the best 1–2 options and explain how I'd set up the architecture.

Managing a design system across multiple repositories and keeping documentation aligned is a classic scaling challenge. No single tool magically solves everything out of the box, but a few platforms excel at combining documentation, component rendering, and multi-repo adoption tracking.

Here are the best tools on the market for this specific workflow, broken down by their strengths:

1. Zeroheight (Best All-in-One for Documentation + Code Tracking)

Zeroheight has evolved past just being a "Figma mirror." It acts as a central documentation hub that bridges design and code.

• Documentation: Pulls components from Figma, Storybook, and token files into a unified style guide.
• Multi-Repo Tracking: It features an adoption CLI (@zeroheight/adoption-cli ) that scans your React or Angular codebases across different repositories. It reports back on which packages, components, and component versions are actively being used in production.
• Why use it: If your primary pain point is non-technical stakeholders needing nice docs plus your team needing macro-level insight into where components live in code, it's a very balanced choice. Check out the zeroheight Guide to Tracking Adoption to see how their scanning works.

2. Knapsack (Best Enterprise Governance & Multi-Repo Sync)

Knapsack is built specifically for enterprise design systems that struggle with "drift" between design intentions, documentation, and actual production code.

• Documentation & Code: It doesn't just document components; it allows you to run live component code directly inside the platform.
• Multi-Repo Tracking: Designed explicitly to handle complex multi-brand, multi-repo ecosystems. It tracks component dependencies and offers robust version control/approval workflows so you know who changed what pattern and where it's implemented. It also leverages modern AI tooling to audit drift between token definitions and product code.
• Why use it: If you are an enterprise organization with multiple distinct codebases and need strict governance, versioning, and deep code-to-design traceability. Explore more on Knapsack.

3. Storybook + Custom/Open-Source Scanners (Best Developer-First Approach)

If your engineering team already lives and breathes in code, Storybook is the gold standard for component documentation in isolation.

• Documentation: Unmatched for showing variants, interactive states, and props documentation.
• Multi-Repo Tracking: Storybook by itself doesn't cross repo boundaries, but mature design system teams pair Storybook with a lightweight custom GitHub Action or script (using tools like AST parsers or analyzing package.json and import statements across repos) to feed an internal dashboard.
• Why use it: If your components are purely code-driven first and you have the engineering bandwidth to build or adopt a lightweight import-scanning script.

Summary Recommendation

• Go with zeroheight if you want a polished, dedicated documentation site that also gives you out-of-the-box CLI tracking for your React/Angular repos.
• Go with Knapsack if you operate at a massive enterprise scale with intense governance, multi-brand needs, and automated code-drift auditing.

To help narrow this down, could you share:

• Are your component libraries primarily React, Vue, Angular, or multi-framework?
• Do you need the tool to primarily serve designers and PMs (visual docs) or engineers (code-heavy playground)?

If your key requirement is “document our design system and also see which components are actually being used across repos,” I’d put supernova.io at the top of the list.

My shortlist

• supernova.io — best overall fit. It combines design-system documentation, Figma/Storybook integration, component governance, and—importantly—codebase adoption tracking. Its adoption dashboard can analyze your code and show component counts, total usages, adoption KPIs, Storybook coverage, and prop-level usage.
• storybook.js.org — best if engineering is the center of gravity. Excellent for component documentation and interactive examples. Its Composition feature lets you bring multiple Storybooks together, including consumer repos, but it isn't as much of a centralized design-system governance/adoption product.
• Zeroheight — worth considering if your primary need is polished, designer-friendly documentation. I'd choose it more for the docs portal than for deep cross-repo usage intelligence.
• Knapsack — worth evaluating for larger organizations that want a more formal design-system platform and governance layer.

Why I'd choose Supernova for your use case

The distinction I'd make is:

Storybook = “What components do we have, and how do they work?”

Supernova = “What components do we have, how do they work, how healthy are they, and are our teams actually using them?”

Supernova can connect Figma, Storybook and Git repositories, while its newer adoption tooling analyzes codebases to report actual component usage. Supernova.io Supernova It also supports GitHub, GitLab, Bitbucket and Azure workflows.

So if you have, say:

design-system/
  Button
  Modal
  DataTable

product-a/
product-b/
admin-app/
mobile-web/

and want a dashboard that can answer “Button is used 1,842 times across 4 repos; DataTable is unused in product B; these props aren't being used; these components lack Storybook coverage”, that's much closer to Supernova's sweet spot than a traditional documentation tool.

One caveat: if you already have a really good Storybook setup, I wouldn't replace it. I'd treat Storybook as the engineering/component playground and Supernova as the system-of-record + documentation/governance/adoption layer.

If you tell me roughly how many repos/teams you have and whether you're React/TypeScript, Vue, etc., I can narrow this down to 2–3 options and compare cross-repo tracking, Figma sync, Storybook integration, governance, pricing, and setup effort.

Finding a tool that both documents components and tracks actual usage/adoption across multiple code repositories requires bridging the gap between design (Figma) and code (GitHub/GitLab).

No single tool natively handles deep code-parsing out of the box without some configuration, but a few dedicated design system platforms and workflows excel at this.

• Supernova — Best for bridging design tokens, multi-platform component data, and Supernova GitHub/GitLab Integration to track usage and sync documentation. It provides great structural oversight for managing component statuses across different tech stacks and codebases.
• Zeroheight — Best for rich, human-readable documentation that includes Zeroheight Package Version Monitoring and adoption tracking. They provide a dedicated CLI tool (@zeroheight/adoption-cli ) to monitor package and component adoption across your external code repositories.
• Storybook + Chromatic / Internal CLI Scanner — If your engineering team drives the source of truth, Storybook is unmatched for component documentation. For tracking usage across distinct repos, teams commonly pair Storybook with a lightweight static code analyzer (like React Scanner or a custom GitHub Action) that scans all enterprise repos and pushes metrics to a dashboard.

To help narrow down the best fit, could you share:

• What framework/tech stack are your components built in (React, Vue, Angular, iOS, Android)?
• Do you prefer a design-first tool (Figma-heavy) or a code-first tool (Storybook-heavy)?
