Free, open-source AI tools from GitHub that fit designers, explained simply.
7 free, open-source tools picked for designers. Newest: PhotoCraft: Free PSD Editor That Works Like Photoshop (2026). Most GitHub stars: Awesome DESIGN.md (121.5K).
These free tools are for people who make things look good: websites, slides, diagrams, photos and brand pages. Some are full apps, like a free Figma alternative that opens .fig files and two Photoshop-style editors that open PSD files. Others are skills and style files that steer an AI helper such as Claude Code, so the pages and diagrams it makes look on-brand instead of generic. Some of them run inside an AI coding helper, and every guide walks you through the setup step by step. Each guide also lists the license and the price, so you know what you are getting before you install anything.
