Figma

Design and prototyping tool used across the industry, with a free Starter plan that covers design files, FigJam whiteboards and slides. Useful for portfolios, pitch decks, wireframes and simple brand assets.

Why I recommend it: Free Starter plan has limits on the number of files and collaborators, and some features (Dev Mode, advanced Figma Make usage) sit on paid seats. Enough for one person building a portfolio or deck without paying.

Magic Patterns — AI design and prototyping

An AI design tool for product teams: turn a prompt, product requirement, or screenshot into high-fidelity UI, match existing design tokens, and explore directions before committing engineering time.

Why I recommend it: For founders without a designer: make something visual before you ask anyone to build it. The free tier is enough to test an idea.
