Figma — Collaborative Design Tool

Figma changed design forever by making it collaborative and browser-based. Multiple designers work on the same file simultaneously — no more version conflicts, no more "which file is the latest?" It's Google Docs for design. For UI/UX design, it's unmatched: auto-layout, components, variables, prototyping, and dev mode are all built in. The plugin ecosystem extends functionality endlessly. FigJam (the whiteboarding tool) is excellent for brainstorming. Free for individual use (up to 3 projects). Professional plan at $12/editor/month unlocks unlimited projects, team libraries, and advanced features. Whether you're a designer, developer, or product manager, Figma has become the central hub for building digital products.
