heimer4.5.0

Create mind maps, diagrams, and structured notes by placing nodes on a canvas and connecting them with labeled edges. Heimer keeps diagram creation deliberately simple and fast, making it useful for planning, lesson material, brainstorming, and organizing ideas. Written in Qt, it is a cross-platform desktop program targeted at Linux and Windows, with Linux as the platform covered here.

Users can add node text and edge labels quickly, zoom the canvas with the mouse wheel, and export finished work as PNG or SVG images. Projects can be saved and reopened in XML-based .ALZ files, preserving an editable format for continued work rather than only a rendered image. English is the default interface language, with translations for Basque, Chinese, Dutch, Finnish, French, German, Italian, and Spanish. The interface language can also be selected with the --lang command-line option when a different choice is preferable.

Jussi Lind’s Heimer 4.5.0 requires Linux with snapd and runs on x86_64 (amd64) systems; it is open-source. Its focused feature set suits students, teachers, writers, and anyone needing a visual outline, classroom diagram, or lightweight note board. The combination of fast node editing, labeled connections, editable project files, and image export distinguishes it from a diagram editor intended only for producing final graphics.
