Private beta waitlist

Stellar reads your design system from the Figma library, the repository and the documentation your team already maintains.

To constrain what agents build to your components and your tokens, so nothing is invented and nothing is typed by hand.

In Figma and in code, with one set of rules on both sides, so a screen and its implementation come from the same library.

first image — Design the main dashboard of Acme, a subscription analytics tool that helps SaaS teams track revenue and churn. Top bar with the Acme logo, a workspace switcher, search, notifications and an account menu. Left sidebar: Overview, Revenue, Customers, Subscriptions, Retention, Settings. Overview is active. Main area starts with "Overview", a date range picker set to "Last 30 days", a comparison toggle vs previous period, and an Export button. Four KPI cards: MRR, Active subscribers, Net revenue churn, Average revenue per account. Each with the value, the delta vs previous period and a small sparkline. Below, an MRR breakdown chart over 12 months (new, expansion, contraction, churned) with a legend, and next to it a smaller donut showing revenue split by plan (Starter, Growth, Enterprise). At the bottom, a table of recent subscription events: customer, plan, event type (upgrade, downgrade, cancellation, trial converted), MRR impact, date. Sortable columns, status badges, pagination, row action menu. Realistic company names and numbers, no lorem ipsum. Include empty and loading states for the table. Light theme, clean spacing, one accent color, accessible contrast.Drag to compare

Questions.

Stellar is in private beta. Where an answer is not settled yet, it says so. If you do not find what you need, write to us at hello@stellar-design.app

Will it work with our design system?: If your components live in a Figma library, in code, or in written documentation, they can be read. One source is enough to start. Connecting more is what lets Stellar keep the link between them.
How was the comparison at the top made?: Both halves were generated from the prompt you can read above the screenshot, against the same design system. On the left, Figma’s own AI, with that library sitting in the file it was working in: it still drew its own components instead of using them. On the right, Claude Code with Stellar, which reads the system and hands it to the agent before it starts.
Is this a component library?: No. Stellar ships no components of its own. Your design system stays the only source of truth, and when it changes, the record changes with it.
What if Figma and the repository disagree?: Reading both is what makes the gap visible: a variant that exists only in code, a component with no counterpart in the library, a token that drifted on one side. Stellar surfaces it. It does not pick a winner, because which side is right is a design system decision, and those belong to the people who own the system.
What does Stellar actually read?: Design tokens, and components with their variants, states, slots, anatomy and usage rules. In Figma and in the codebase both, described in the same terms on either side, which is what makes the two comparable at all.
Where does our design system data go?: This is the first thing we settle with every beta team, and we would rather answer it in a conversation than publish a policy we have not finished implementing. Write to us and you will get a straight answer about what is stored and where. hello@stellar-design.app
Does Stellar write the code?: No. Your agent does, in your repository and your conventions. Stellar gives it the knowledge of your system, so what comes out is shaped by your project rather than by us.

Teach your design system to your AI agent.

What happens next

You join
Three questions: your role, the size of your company, and the setup you design in today.
We select
A person reads the answers and picks the teams whose setup fits what the beta needs to learn. Small groups, not everyone at once.
You test, free
Selected members get the beta at no cost, and we ask for your feedback while you use it. What is stored, and where, is settled before anything of yours is connected.
