Introduction

Isotop is a Figma plugin for building and maintaining design token systems. It does two jobs: it generates a token system for you with Collider AI, and it gives you the controls to keep the variables you already have structured and predictable. Collider builds the system in two layers: the primitives first, then the semantic roles that alias them. It works group by group and stops after each one for you to review, checks contrast while the layer is built, and carries every value in each mode from the start. Nothing reaches your Figma file until you apply it, and then it lands as real variables with their aliases intact. For the variables you already have, Isotop lets you mark core colors as a single source of truth, link design tokens to them individually or in bulk, and generate palettes from reusable recipes. Every change is previewed in a sandbox and applied only when you sync, with Undo and Redo on every core action. Where to start: if you want to generate a system, read How Collider works. If you are managing a system you already have, read Core Variables.
