of day-to-day design-system work automated by Supernova agents
vs. drowning in documentation busywork that never ends
>10x
faster design system adoption across your teams via in-tool integrations
vs. begging people to read your docs
>70%
fewer tokens spent on every prompt your team or agent runs
vs. pasting entire sites into prompts and hoping
“All the support we've received since our arrival shows just how much better it is to be here .”

Zeroheight customers have spoken
Sourced from G2 reviews, Capterra, Reddit, and user reports.
01
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Teams report spending more time fixing broken syncs, phantom content, and outdated pages than actually documenting.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.
02
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.
03
Limited platform depth
AI features remain basic, analytics and adoption tracking fall short, and core operational capabilities are either missing or underpowered.
04
Design and code stay disconnected
The gap between design sources, documentation, and production still requires constant human effort to keep everything aligned.
The gap
Supernova laps Zeroheight
Linked design system graph
Docs plus tokens, components, rules, and skills — the system you actually wanted.
Agents that take action
Automate day-to-day work with Claude, Cursor, or Supernova’s own agents.
Real-time multiplayer
Notion-like editing in real time. Write together, ship together.
Built-in feedback loop
See how people and agents use the system, then close the gaps.
Precise data distribution
Scope exactly what each team and agent needs — nothing more.
Made to meet the true reality
Teams and agents need the system as ground truth, not another site to scroll.
Agent-native
A glimpse of what your team can do with Supernova
Four kinds of work, one system behind them. Slide through the deck, or pick a kind.

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.

Design system data
Design systems
Manage multiple systems in one place
Yes
Yes, but..
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.
Figma data sources
Import components and assets from Figma
Yes
Yes, but..
Reported as no.1 thing that doesn't work reliably
Storybook data sources
Import stories into interactive playgrounds
Yes
Yes
Automatic data source updates
Auto-update when sources change
Yes
All changes propagate autonomously in the background once per hour
No
No indication that anything changes - you must request to update data from upstream sources manually and keep track of it yourself
Token management
Create and manage design tokens in-product
Yes
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
No
Read-only table of imported tokens from Figma

Data Contexts
Data Contexts
Distributable packages of tokens, components, assets, docs, skills, knowledge and other information
Yes
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)
No
Zeroheight doesn't manage tokens, components, assets, skills or anything else beyond documentation

Powerful rule-based system so your AI, MCP and docs so you always distribute what you want, no matter what changes you make
No

Yes
No
AI & MCP
Dedicated Remote MCP server
MCP server to access data from
Yes
Full access to tokens, components, resolved themes, assets, skills, knowledge, semantic search tools, skill hosting and 40+ more MCP tools
Yes, but..
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
Local MCP server to access data from
No
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
Yes
MCP Write capabilities
Let agents create and update design-system data
Yes
Agents can write docs, modify components, and contribute tokens through MCP — the same day-to-day actions a maintainer would do by hand.
No
Background agents
Assign Supernova agent onto task and let it work
Yes, but..
Rolling out now to early-access customers — long-running tasks like full-system audits and proposed changes, running autonomously in the background.
No
Skills & Knowledge
Agent Skills
Portable packages of instructions, scripts, and resources for agents
Yes
Give agents specialized capabilities and domain expertise. Attach them to a context and distribute via MCP.
No
Knowledge files
Upload generic resources for agents to use
Yes
Generic uploaded resources made available through MCP alongside your design-system data.
No
Feedback
Context feedback
Collect feedback on contexts from AI usage
Yes
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.
No
Developer platform
