Free Design Tools Every Developer Should Know About

Paid design tools are good. Free design tools have quietly become very good. If you are a developer who occasionally needs to design something, or a designer who cannot expense software yet, this list is for you.

Vector and UI Design

Figma (free tier) — figma.com (opens in a new tab)

Three projects, unlimited collaborators on free files, and access to the full editor. For most solo work and small teams, the free tier is enough. The community tab has thousands of free UI kits, icon sets, and templates.

Penpot — penpot.app (opens in a new tab)

Open source, self-hostable, and genuinely usable. Built on SVG standards, which means files export cleanly and predictably. A strong alternative if you want to avoid vendor lock-in.

Inkscape — inkscape.org (opens in a new tab)

Free, open source vector editor. Not as smooth as Illustrator but capable of everything Illustrator can do. Best for complex illustration and print-ready work.

Image Editing

Photopea — photopea.com (opens in a new tab)

Photoshop in the browser. Runs without installation, opens PSD files, supports layers, masks, and blend modes. Genuinely impressive for a free web app.

GIMP — gimp.org (opens in a new tab)

The long-standing open source image editor. Steep learning curve compared to Photoshop but full-featured and well-documented.

Color and Typography

Coolors — coolors.co (opens in a new tab)

Fast palette generation. Lock colors you like and regenerate the rest. The contrast checker is useful for accessibility work.

Google Fonts — fonts.google.com (opens in a new tab)

Over 1,500 font families, all free for commercial use. The Knowledge section explains type concepts alongside the library.

Fontsource — fontsource.org (opens in a new tab)

Self-hosted versions of open source fonts, installable as npm packages. Better for performance than loading from Google's CDN in production.

Icons and Illustrations

Lucide — lucide.dev (opens in a new tab)

Clean, consistent icon set. Available as SVG, React components, and more. MIT licensed.

Heroicons — heroicons.com (opens in a new tab)

Made by the Tailwind team. Two sizes, outline and solid variants. Works well with Tailwind utility classes out of the box.

unDraw — undraw.co (opens in a new tab)

Open source illustrations with a color picker that updates every image to match your brand color. MIT licensed and regularly updated.

Storyset — storyset.com (opens in a new tab)

Animated and static illustrations, customizable by color and style. Free with attribution.

Prototyping and Wireframing

Whimsical — whimsical.com (opens in a new tab)

Fast wireframing, flowcharts, and mind maps. The free tier covers most early-stage prototyping needs.

Excalidraw — excalidraw.com (opens in a new tab)

Open source whiteboard tool with a hand-drawn aesthetic. Good for quick sketches and communicating ideas without needing polish.

The tools you use matter less than how consistently you use them. Pick one from each category, get fluent with it, and only switch when you hit a real limitation.
