OmniPackage

OmniPackage is an open-source command line tool for turning a software project into native Linux packages for multiple distributions and publishing them through a repository the developer controls. It is aimed at the awkward gap between having a working application and giving Linux users a normal installation and update experience. Rather than asking every user to download a loose archive or learn a language-specific package manager, a maintainer can ship packages that work with apt, dnf, zypper, or pacman. OmniPackage handles the repetitive packaging and repository work from one project configuration, whether the release runs on a laptop or in continuous integration.

The build process begins by scaffolding the files expected by the target package ecosystems. OmniPackage can generate RPM specifications, Debian package files, and PKGBUILD files, then run the native build tools inside a container for each chosen distribution. Building within the target distribution matters because the resulting software links against that distribution's own libraries and declares dependencies as native packages. The system package manager can then resolve those dependencies instead of relying on a bundled runtime. OmniPackage uses tools such as rpmbuild, dpkg-buildpackage, and makepkg behind one release workflow, which reduces the amount of distribution-specific packaging knowledge a small project needs to carry.

Packaging is only part of a release. OmniPackage signs packages with the maintainer's GPG key and publishes the output to an S3-compatible bucket or a local directory. AWS S3, Cloudflare R2, and MinIO are among the storage options named by the project, while local output is useful for testing. The chosen location becomes the project's own package repository. OmniPackage also generates an installation page that maintainers can share with users. That page provides the repository setup and package installation steps appropriate to a visitor's distribution. Once a user adds the repository, future versions arrive through the same system update commands used for distribution packages. The project doesn't store packages itself, so the binaries, metadata, and hosting relationship remain under the maintainer's control.

A YAML configuration describes builds, repositories, version extraction, image caches, secrets, and related release settings. Maintainers can run the full process with the release command or separate building and publishing when a pipeline needs finer control. The documentation includes a reusable GitHub Actions pattern that expands supported distributions into a job matrix and keeps stable and development channels separate. It also shows how to cache container images so repeat builds don't reconstruct every target environment from scratch. Example projects are available for C, C++, CMake, Rust, Go, Python, Ruby, Crystal, Electron, and Tauri, while the package content can be proprietary even though OmniPackage itself is open source.

OmniPackage fits independent developers and small release teams that want broad Linux distribution without running a different manual packaging process for every ecosystem. It is especially useful when native dependency resolution and ordinary system updates are more important than bundling an application with its own runtime. That is its key difference from formats such as Snap, Flatpak, and AppImage. Those approaches package or supply more of the runtime, while OmniPackage deliberately builds native DEB, RPM, and pacman packages for repositories managed by the project. It can also suit organizations that need packages in private or internal object storage, since publishing isn't tied to a central app store or a particular cloud.

The project is free under the GPL-3.0 license and requires no OmniPackage account, subscription, or credit card. It does expect the maintainer to bring several operational pieces. Builds need Podman or Docker, packages need an appropriate signing key, and production publishing needs an S3-compatible bucket or another selected directory. Builds follow the host architecture, with the documented targets covering x86_64 and ARM64 where the base image supports them. The scope is intentionally narrower than a universal Linux release service. OmniPackage doesn't build Flatpak, Snap, AppImage, AUR, or Nix outputs, doesn't host the repository for the developer, and doesn't sandbox installed software. For teams comfortable owning storage and CI, those limits preserve a direct, native distribution path.
