FModel Linux — Unreal Engine Archives Explorer for Linux

See the repository Actions tab for CI status and the Releases tab for downloadable builds.

This is an unofficial Linux port of FModel, originally created by Asval (4sval) and contributors. It is not affiliated with or endorsed by the upstream project or its maintainers. Please do not report Linux-port-specific issues upstream.

Description

FModel Linux is a Linux port of FModel — an archive explorer for Unreal Engine games. It uses CUE4Parse as its core parsing library, providing robust support for the latest UE4 and UE5 archive formats, along with a comprehensive set of tools for previewing and converting game packages.

This fork replaces the Windows-only WPF UI stack with Avalonia UI and removes other Windows-specific dependencies to enable native Linux support. This repository may be maintained by a downstream fork owner, while continuing to credit r6e for the Linux-porting work and the upstream FModel developers for the original project.

Attribution

• Upstream project: FModel by Asval (4sval) and FModel contributors.
• Linux port foundation: r6e/FModel-Linux.
• This repository/fork: may add packaging, documentation, or further Linux fixes, but should continue to preserve visible credit to both r6e and the upstream FModel developers.

Installation

Release builds now ship with:

• a portable Linux tarball for manual installation,
• a Debian package (.deb) for Debian/Ubuntu-based distributions,
• an Arch packaging bundle (PKGBUILD + desktop entry) for Arch-based distributions.

The GitHub release workflow publishes those artifacts automatically. Local wiki-style documentation for this fork is available in docs/wiki/Home.md, including install and packaging guides.

For local packaging, the process is intentionally simple:

• run scripts/package-linux.sh to generate everything in one command,
• or run scripts/build-portable.sh, scripts/build-deb.sh, and scripts/build-arch.sh individually if you only need one artifact type.

For the upstream Windows release, refer to the official FModel installation guide.

This fork does not accept donations. If you find FModel valuable, please consider supporting the original FModel project and its contributors.
