Figma

Figma is a browser-based interface design tool where multiple people can work in the same file simultaneously, with everything stored and versioned server-side.

That collaboration model changed how design and engineering work together: developers inspect the file directly for spacing, colours and assets rather than waiting for a handoff document, which removes an entire category of miscommunication.

Components and shared styles let a design system live in the file itself, so a change to a component propagates everywhere it is used — the practical mechanism behind consistent interfaces at scale.
