Cambalache 1.0 Released After Five Years For Designing Modern GTK UIs

Written by Michael Larabel in GNOME on 20 March 2026 at 08:48 PM EDT. 20 Comments
Cambalache 1.0 released today after more than five years in development as a What You See Is What You Get (WYSIWYG) application for creating and editing user interfaces for both GTK3 and GTK4.

The Cambalache 1.0 release marks the milestone of the app being mature enough for common general feature usage. The goal is to help developers avoid the need to write manual XML UI files and the expectation of the Cambalache user is that they are at least familiar with the Gtk and GtkBuilder format.

Cambalache 1.0 should be good for starters while future releases will focus on enhancing its own user interface as well as further enhancing this Python-based application in other areas.
