TikZ Editor

TikZ Editor is a free, open-source visual editor for creating and editing TikZ diagrams used in LaTeX documents. Users can drag elements to adjust positions, and the underlying code updates instantly without affecting formatting like line breaks or indentation. The editor works both as a web application and lightweight desktop app, supporting common TikZ features including loops and offering tools to add paths, nodes, shapes, and text.

Designed for academics and researchers who write LaTeX papers, the editor eliminates tedious manual coordinate tweaking by providing a dual-panel interface showing both visual and source views in real-time sync. Additional features include snapping for alignment, rulers, guide lines, syntax highlighting, and error detection. The maker notes the app was built almost entirely with Codex.
