What Sets Fog Panther Apart

Persistent Undo History - The full editing history is saved inside the project file. Close a project, reopen it weeks later, and undo all the way back to the beginning.

Embedded Fonts - Every font used in a project is stored in the file. Open it on any machine and the text renders correctly. No missing fonts, no broken layouts.

Native FOG Format - A proprietary project format with compression, encryption, full undo history, and embedded fonts. Designed to preserve every aspect of a project.

No Account. No Cloud. No Lock-In. - No sign-in, no internet connection required. Files live on the user's machine and nowhere else.

Native Linux Experience - Built with GTK4 from the ground up. Respects the system theme, integrates with the GNOME desktop, and includes Nautilus thumbnailing for .fog and .psd files.
