Answer in brief
Figma variables hold a design’s reusable values, such as colors and numbers, with a value per mode, and Figma can import and export them as JSON in the W3C design tokens format. Code Connect links each Figma component to the component in your code, so Dev Mode and Figma’s MCP server hand an agent your real code instead of a guess. Together they keep the design file and the codebase saying the same thing.
Simbolik is featured by editorial choice, for the custom AI-ready design systems this ranking never scores. Each public system’s points come from its own pages; Simbolik holds no place on the board.
What they are
Variables store reusable values in a Figma file and apply them to design properties and prototypes. They sit in collections, and each can hold one value per mode, such as light and dark. Figma names design tokens as a use for them. A collection can also import JSON files in the Design Tokens Community Group’s format, one mode per file, and export each mode back to JSON.
Code Connect links a component in your repository to the matching component in a Figma design file. Dev Mode then shows your production code for it instead of a generated example. You set it up with a CLI that publishes the links from your project, or in Figma’s own UI with a GitHub connection, which can map one design component to several code versions.
Where they meet the ranking
The ranking reads a design system’s public pages, not its Figma files, so neither feature earns a point directly. Both feed the parts that do. Variables exported as W3C JSON are design tokens as data, the first column. Code Connect feeds agent access: Figma says its links give agents using its MCP server direct references to your actual code, so a frame turned into code uses the components you already have.
Before you adopt them
- The import is strict. A dimension must be in px and a duration in s; a font family must be a single name; a variable is created only for a design token that appears with the same type in every file imported together.
- Exports are per mode. You export one mode, or every mode of a collection, as JSON files.
- Plans. Code Connect needs a Dev or Full seat on a Professional, Organization or Enterprise plan. Figma’s desktop MCP server needs a Dev or Full seat too; its remote server, which Figma recommends, runs without the desktop app.
- Code Connect’s routes. Figma now recommends its template files for any codebase, and calls the React, HTML, SwiftUI, Compose and Storybook guides legacy.
If your design tokens start in Figma, these are how they leave it. An MCP server for your design system covers the agent side, and the best AI-ready design systems, ranked show which public systems publish their design tokens as data today.
Questions & answers
Professional, Organization and Enterprise, on a Dev or Full seat. Professional is limited to one active library and one framework; Organization and Enterprise allow several frameworks.
Its help page shows aliases written as references inside a file, and uses its own com.figma.aliasData extension for references across collections. Test an export of your own collection before you build a pipeline on it.
