Supernova
Supernova brings design system information, code data, documentation, and AI context together as a shared source for teams and agents. It tracks component health, manages design tokens, and supports multiple brands in one workspace. Its documentation editor supports real-time collaboration, page history, and publishing. Through MCP, it provides filtered design system context to AI tools including Cursor, Copilot, and Claude Code.
Code automation can export tokens and open a pull request when design system changes are made. Listed integrations include Figma, Storybook, Tokens Studio, GitHub, Azure, Bitbucket, GitLab, and VS Code; pre-built integrations are included in the Free plan. The Free plan supports up to five seats and limits documentation pages, connected data sources, page history, and analytics periods. Pro costs $35 a month per editor seat. Supernova Portal is available on the web, and its desktop app is currently available only for Mac.
