Figma
Collaborative UI design tool
Free tier + paidDesign tools, color & typefigma.com
What it is
Browser-based interface design and prototyping tool, and the file format the design world exchanges work in. Covers vector editing, auto layout, components and variables, multiplayer editing, prototyping, and Dev Mode, which exposes measurements and CSS or SwiftUI snippets to whoever is building the thing.
Why it earns a slot
Even if you never draw a frame, clients and designers hand you Figma links, and Dev Mode turns them into spacing values, hex codes and CSS you can paste. The free tier reads any file you are invited to.
Know before you commit
The free Starter plan caps you at three files in one team. Figma bills by seat type — a full design seat costs more than a Dev or Collab seat — so check which one a collaborator actually needs before adding them.
Neighbourhood
How Figma sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
