Looking for amodern alternativeto GitBook?
GitBook gives you a genuinely good docs site. What sits behind it is still Markdown — not the system.
of day-to-day design-system work automated by Supernova agents
vs. Markdown that describes a system living somewhere else
faster design system adoption across your teams via in-tool integrations
vs. hoping people bookmark the docs site
fewer tokens spent on every prompt your team or agent runs
vs. pasting entire spaces into prompts and hoping
“All the support we’ve received since our arrival shows just how much better it is to be here .”
Supernova laps GitBook
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.
Built-in feedback loop
See how people and agents use the system, then close the gaps.
Made to meet the true reality
Keep GitBook for product docs. The design system needs to be data.
Skip the pitch. See it for yourself.
GitBook teams have spoken
Read against each product’s published capabilities and documentation, August 2026.
The pages are the product
GitBook is strong at published docs. It is not connected to Figma, and it does not manage tokens, components, or properties as data.
Git versions the copy
History and review are real. The token values in the Markdown are still copies of Figma and Storybook. Git cannot tell when the original moved.
Docs MCP serves prose
The GitBook MCP server returns your pages. An agent building UI needs token values and component properties, not the Markdown describing them.
An embed is not component data
A Storybook iframe shows the component render. The page still does not have properties, variants, or an API it can query or export.
Welcome
Supernova Agent
to your team.
Connect your data, document it, keep it clean and ship it to code. The agent does the work. You approve what matters.
Good morning, Alex
What makes Supernova the best GitBook alternative
Design sources
Variables, collections and components as data
You can embed a frame, not import a system
Stories, props and APIs, connected
An iframe, with no component data behind it
The system refreshes itself, on its own
An agent can rewrite it. Nothing tells it to.
Design system data
A real source of truth for tokens
Types, aliases, history and versions
A table of values copied from somewhere else
Structured data, not embedded images
One system, many brands and themes
No theme layer — a brand is a separate copy
Versions of the system, not the page
Docs versions, not system versions
Documentation
Live previews, token tables, spec blocks
Generic blocks. Images, not live components.
Real-time multiplayer editing
Publish under your own brand
Distribution and code
Design data out as platform code
Git sync ships pages, not tokens
Query the system programmatically
Content API — pages, not system data
AI and agents
Agents read the system, not a page
Tokens, components and docs together
Docs MCP serves your published text
Each agent gets only its slice
Rules that travel with the system
Change the system, not just read it
Agents edit pages, not the design system
See where people and agents hit gaps
Docs insights, not system adoption
Everything else your company writes
The rest of how a company writes
Not what it is for. Keep your wiki.
Product docs rather than a company wiki
Switching is easier than staying
“We were prepared for a steep learning curve, but it turned out to be a smooth glide.”
- 1
Open GitBook to your agent
GitBook opens its content through its docs MCP server and content API. Give Claude or Cursor read access to your space.
- 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 space over. It rebuilds the structure in Supernova in minutes — no export scripts, no rewrite sprint.
- 4
Keep GitBook for product docs
Product and API documentation that has nothing to do with the design system stays in GitBook. Supernova takes the layer underneath the pages.
