All test builds for Glimpse are hosted on https://build.glimpse-editor.org
The beta testing builds we produce offline can be found in https://build.glimpse-editor.org/beta/
Initially they are provided as ZIP files you can run from any location on your hard drive, but in due course there will be MSI installers provided too.
The 32-bit Windows builds are provided in the win32 folder, and the 64-bit Windows builds are provided in the win64 folder.
If you haven't done so already, you first need to install Flatpak and enable Flathub on your machine. Glimpse depends on the GNOME platform runtime which is distributed by Flathub.
We provide our own Flatpak repository with builds from our development branch. To enable it, just download and install the Glimpse Devel repository file.
If clicking on the above link doesn't open your software center to add the repository, you can also manually add it in a terminal:
$ flatpak remote-add --if-not-exists glimpse-devel https://build.glimpse-editor.org/dev/flatpak/glimpse-devel.flatpakrepo
Next, either find Glimpse development builds in your software center, or install it in a terminal:
$ flatpak install glimpse-devel org.glimpse_editor.Glimpse
