makeself

Overview

Makeself turns a directory into a compressed TAR archive that runs as a shell script. It is best for developers and administrators distributing software or installation scripts across Unix-compatible systems. Its focused packaging model is a good fit for command-line delivery, but not for building native application bundles.

Key features

Each archive combines a TAR payload with a shell stub. On launch, the stub extracts files to a temporary directory, can run an optional command such as an installer, and removes temporary files afterward. That keeps a basic software handoff self-contained, while leaving recipients to run it in an environment with a compatible Bourne shell.

Recipients can list the archive's contents, check its integrity, choose where to extract, request confirmation, or skip the embedded command. CRC and MD5 checksums are supported, with SHA256 as an option. These controls help recipients inspect or validate a package and decide whether to run its command; they do not remove the need to trust the package itself.

Packagers can choose among gzip, bzip2, bzip3, xz, lz4, zstd, and other compressors. The range is useful when a project has a preferred compression method, but anyone extracting the archive needs the matching compressor for non-default methods. GPG and OpenSSL encryption are also supported, with the same practical caveat: archive users need the relevant tool installed.

Makeself avoids Bash-specific features and targets Unix-compatible systems with a Bourne shell. The maintainer identifies Linux, macOS, Solaris, HP-UX, SCO OpenUnix and OpenServer, AIX, IRIX, FreeBSD, OpenBSD, NetBSD, UnicOS/Cray, and Windows through Cygwin or WSL as tested. Older archives made before version 2.1.2 can encounter extraction problems on some GNU/Linux distributions due to obsolete head and tail syntax.

The project is licensed under GNU GPL version 2 or later, while archives made with it do not have to carry that license. A Maven plugin supports integration, with usage and bug reports handled through the plugin's project. The maintainer also invites patches and bug reports through GitHub and provides an email contact for suggestions.

Pricing

Makeself is free: the Makeself plan costs nothing under GPL version 2 and above. It provides self-extracting archives for Unix-compatible systems, with no paid tier or trial to weigh against it. The main cost is operational: recipients may need compatible shells, compression programs, or encryption tools installed, depending on how an archive was created.

Platforms

The target platforms include Linux, macOS, and Windows through Cygwin or WSL, as well as Solaris, HP-UX, AIX, FreeBSD, and OpenBSD. The broader tested list also includes SCO OpenUnix and OpenServer, IRIX, NetBSD, and UnicOS/Cray. Windows support depends on a Unix-like compatibility environment, so Makeself is not a native Windows installer format.

Who it's for

Makeself suits teams that need to deliver a compressed directory with a shell-based extraction or installation step, especially when users already work in Unix-like environments. Its command-line packaging and configurable extraction behavior suit scripts and utilities. Teams distributing desktop applications that need OS-specific bundles should choose a tool built for that job instead.

Pros and cons

• Pros: A free, focused format packages files and an optional command together, then cleans up temporary files after extraction.
• Pros: Recipients can inspect contents, validate checksums, choose an extraction target, request confirmation, or skip the embedded command.
• Pros: Multiple compression methods and optional GPG or OpenSSL encryption give packagers flexibility when the required tools are present.
• Cons: Extraction requires a compatible Bourne shell, and Windows users need Cygwin or WSL.
• Cons: Non-default compression and encryption depend on corresponding programs installed by archive users.
• Cons: Its shell-archive format does not provide the OS-specific app bundles offered by packaging tools aimed at desktop applications.

Alternatives

Choose Tauri Bundler when you need OS-specific app bundles for Rust executables across Android, iOS, Linux, macOS, or Windows; its public API stability is not strictly SemVer. Electron Forge, electron-builder, and electron-packager are free options for Linux, macOS, and Windows; electron-packager is an open-source Node.js library and CLI that requires Node.js 22.12.0 or higher.

nFPM is another free choice spanning Linux, macOS, web, and Windows. InstallAware has a free Visual Studio edition for commercial use and also offers a free trial. IzPack is free under Apache License 2.0 and supports self-hosted use. NSIS is free for any use, produces installers up to 2GB, and runs generated installers on Windows.

Verdict

Makeself is a strong, no-cost choice for developers and administrators who want to hand off a directory as a self-extracting shell archive with checks and an optional install command. Its flexibility is useful when recipients have compatible shells and tools; look elsewhere when distribution calls for native app bundles or Windows-native installers.
