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
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
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
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
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
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
Fast palette generation. Lock colors you like and regenerate the rest. The contrast checker is useful for accessibility work.
Google Fonts — fonts.google.com
Over 1,500 font families, all free for commercial use. The Knowledge section explains type concepts alongside the library.
Fontsource — fontsource.org
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
Clean, consistent icon set. Available as SVG, React components, and more. MIT licensed.
Heroicons — heroicons.com
Made by the Tailwind team. Two sizes, outline and solid variants. Works well with Tailwind utility classes out of the box.
unDraw — undraw.co
Open source illustrations with a color picker that updates every image to match your brand color. MIT licensed and regularly updated.
Storyset — storyset.com
Animated and static illustrations, customizable by color and style. Free with attribution.
Prototyping and Wireframing
Whimsical — whimsical.com
Fast wireframing, flowcharts, and mind maps. The free tier covers most early-stage prototyping needs.
Excalidraw — excalidraw.com
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.
