UNOFFICIAL-1.5.5-2026.07.01

SynfigStudio-UNOFFICIAL-1.5.5-2026.07.01-linux64-4d488.AppImage

Built from BobSynfig/synfig:master (which is a copy of synfig/synfig:master) with morevna-builds system

Modifications

Converted to linux64 AppImage v2 for smaller size and portability features.
Added "branding" as a reminder that it is not an official build (Splash screen, Main window + About dialog)
Removed duplicated libs making them as symlink as it should be (also spares disk space)

Make it Portable

Make it portable by creating .home and .config subfolders in the same folder as your AppImage with the exact same name plus the extensions.
You will avoid to mess your official install of SynfigStudio and you can keep your settings with the application on a USB stick even on another computer.

mkdir SynfigStudio-UNOFFICIAL-1.5.5-2026.07.01-linux64-4d488.AppImage.home
mkdir SynfigStudio-UNOFFICIAL-1.5.5-2026.07.01-linux64-4d488.AppImage.config

You should rename the whole as Synfig-UNOFFICIAL.AppImage, everytime you download a new version, so you could keep your current portable settings.

Synfig CLI

In order to use synfig cli with this build, call this AppImage with the parameters --exec synfig

To make it easier to use, you can create 2 bash scripts (make them executable, without extension)

synfigstudio :

#!/bin/bash
APPIMAGE=SynfigStudio-UNOFFICIAL-1.5.5-2026.07.01-linux64-4d488.AppImage
./$APPIMAGE "$@"

synfig :

#!/bin/bash
APPIMAGE=SynfigStudio-UNOFFICIAL-1.5.5-2026.07.01-linux64-4d488.AppImage
./$APPIMAGE --exec synfig "$@"
