G3W-SUITE, an open source web GIS platform, ready to publish your QGIS projects as interactive web maps on first boot.
G3W-SUITE (g3w-admin) is a modular framework for publishing QGIS projects as interactive web maps and managing them through the browser. Built on Django with QGIS Server, it turns desktop QGIS projects into online mapping applications, lets you administer layers, groups, users and permissions, and enables web based editing of spatial data, backed by PostgreSQL with the PostGIS extension.
cloudimg ships G3W-SUITE as the official Docker Compose stack on Ubuntu 24.04, hardened and fully patched, with QGIS Server, PostGIS and Redis preconfigured. Every secret is regenerated per VM and a fresh administrator is created on first boot, the deployment is paired with a step by step guide, and the image is supported 24/7.
