Looking for a modern alternative to Zeroheight?
A design system is not just a documentation site anymore. In the era of AI agents it has to hold the real decisions — tokens, assets, components, patterns, and rules — and present them so both your teams and your agents can act on them.

Why teams choose
Supernova instead?
of day-to-day design-system work automated by Supernova agents
vs. drowning in documentation busywork that never ends
faster design system adoption across your teams via in-tool integrations
vs. begging people to read your docs
fewer tokens spent on every prompt your team or agent runs
vs. pasting entire sites into prompts and hoping

teams in the industry

how much better it is to be here.

Constant cleanup
Teams report spending more time fixing broken syncs, phantom content, and outdated pages than actually documenting. Design changes rarely stay accurate without ongoing manual work.
No real system management
There is little support for ownership, status, lifecycle, or governance of the design system as a whole. Users describe it as a documentation site rather than a platform that helps run and scale the system.
Limited platform depth
AI features remain basic, analytics and adoption tracking fall short, and core operational capabilities are either missing or underpowered.
Design and code stay disconnected
The gap between design sources, documentation, and production still requires constant human effort to keep everything aligned.

Supernova laps Zeroheight
Linked design system graph
Docs are a great start. Now add everything else — tokens, components, rules, skills, knowledge, feedback — and you get the design system you always dreamed of.
Agents that take action
Most day-to-day design system work can be fully automated — by external tools like Claude or Cursor, or by Supernova’s own agents. Just focus on what really matters.
Real-time multiplayer
A best-in-class Notion-like editing experience where everything happens real-time. Write together and ship together too, as a team.
Built-in feedback loop
A design system doesn’t improve on its own. Supernova watches how people and agents use it, surfaces gaps, and helps the whole system get better.
Precise data distribution
Dumping entire docs into a prompt isn’t distribution — it’s leakage. Supernova scopes exactly what each team and agent needs, so the right knowledge shows up and nothing else.
Made to meet the true reality
Docs-first tools were built for a world where the design system lived in a browser tab. That world is gone. Supernova supports teams and agents that need the system as a ground truth — not another site to scroll.

Design system data
Manage multiple systems in one place
In Zeroheight, you manage "styleguide", not a design system. Styleguide is set of documentation pages that export to docs site. Zeroheight doesn't manage your design system beyond importing tokens from Figma and writing docs.
Import components and assets from Figma
Reported as no.1 thing that doesn't work reliably
Import stories into interactive playgrounds
Auto-update when sources change
All changes propagate autonomously in the background once per hour
No indication that anything changes - you must request to update data from upstream sources manually and keep track of it yourself
Create and manage design tokens in-product
Full token manager with bulk actions through AI, option to create and manage tokens from Supernova, 23 token types (spacing, typography etc.), fully customizable custom properties, theming, branding and more
Read-only table of imported tokens from Figma
Manage design and code components together
Custom components, design components, code components, custom properties such as component statuses, health and more
Components can only be put into documentation as a documentation block
Manage assets from Figma and uploads
Read-only asset manager, sourced by Figma data, custom asset uploads for docs
Custom asset uploads for docs
Import Figma variables, modes, and collections
Create a snapshot of design system in time
Split data by platform or brand
Measure design system usage and impact
Docs usage tracking, component usage tracking
Docs usage tracking, component and token usage tracking
Data Contexts
Distributable packages of tokens, components, assets, docs, skills, knowledge and other information
Full control over how your design systems get distributed, full control over segmentation of data (prepare data packages for humans and AI separated by platform, by team, by department - fully up to you)
Zeroheight doesn't manage tokens, components, assets, skills or anything else beyond documentation
Construct data context using rule-based system
Powerful rule-based system so your AI, MCP and docs so you always distribute what you want, no matter what changes you make
Merge or layer contexts to enable data inheritance
AI & MCP
MCP server to access data from
Full access to tokens, components, resolved themes, assets, skills, knowledge, semantic search tools, skill hosting and 40+ more MCP tools
Access structure and content of styleguide. Embedded data like storybook stories are not propagated through MCP at all, making it effectively useless.
Local MCP server to access data from
Vast majority of users don't want to self-host and bother with local MCP servers, as remote server does everything local can, and more
Let agents create and update design-system data
Full control over the entire Supernova data layer, without any compromise. Agents are able to write docs, modify components, contribute tokens and nearly all other actions that maintainers of design systems do day-to-day.
Assign Supernova agent onto task and let it work
Supernova agents are able to perform long-running tasks fully autonomously, such as full-scale audits of design systems, proposing changes, writing components and their docs, and anything else you can think of
Skills & Knowledge
Portable packages of instructions, scripts, and resources for agents
Give agents specialized capabilities and domain expertise. Attach them to a context and distribute via MCP.
Upload generic resources for agents to use
Generic uploaded resources made available through MCP alongside your design-system data.
Feedback
Collect feedback on contexts from AI usage
Your consumers can send feedback from their AI tool via MCP — missing guidelines, wrong tokens, gaps — and it is stored on the context for the owning team to act on.
Developer platform
Turn design system data into code
Export all data, tokens, components, assets, even skill packages as plugins.
Only token export
Ship fully custom TypeScript code exporters
Full control over exported output, custom scripting via typescript routines and Supernova SDK
No control, only pre-defined formats for tokens. No customization possible.
Run exporters and SDK access in your own pipelines
Full access to data through Supernova SDK or exporters invokable through Supernova CLI
Read and write data via SDK
Fully matching the entire feature set of Supernova, both read and write

A glimpse of what your
team can do with Supernova
- Generate a new button variant that matches our existing tokens
- What's the correct spacing token for card padding?
- Review accessibility of my login screen
- Create a dark-theme version of this component
- Which components use the primary color token?
- Update the border-radius across all form elements
- Show me the usage guidelines for the modal
- Does this component meet WCAG 2.2 AA?
- Generate React code for the data table using our system
- What patterns do we have for empty states?
- Flag any components that still use hard-coded colors
- Suggest a better token structure for our spacing scale
- Pull the latest API props for the Select component
- How should error messages be written in our system?
- Create documentation for the new badge component
- Which teams are still using the deprecated button?
- Convert this Figma frame into system-compliant components
- What's the recommended elevation for floating panels?
- Audit this screen for token and component consistency
- Propose a new status indicator based on our existing patterns
Switching is easier
than staying
“We were prepared for a steep learning curve, but it turned out to be a smooth glide.”
- 1
Open Zeroheight to your agent
Connect the Zeroheight MCP server so Claude, Cursor, or any agent can read your existing documentation.
- 2
Give it the keys to Supernova
Hook Supernova’s edit capabilities into the same agent — it can write designs, code, Figma links, and docs straight into the system.
- 3
Say the word. Watch it move.
Ask your agent to port the documentation over. It rebuilds the structure in Supernova in minutes — no export scripts, no rewrite sprint.
- 4
Land upgraded, not just moved
While it’s there, the agent layers on the graph, contexts, and skills. You switch off Zeroheight already ahead of where you started.
