The original
p7zip
Command-line port of 7-Zip's compression tools for POSIX systems.
Replacements
Listings that take over the same core job as p7zip.
7-Zip
The small, free archiver that opens practically every archive format and compresses better than ZIP.
7-Zip is the original project with active development and now ships its own console builds for Linux and macOS, plus a graphical app on Windows.
PeaZip
A cross-platform archive manager that reads over two hundred formats and has a real file manager built in.
PeaZip adds a native graphical interface on Linux and macOS, reads over 200 formats and includes a file manager, under the LGPL-3.0 license.
ouch
Command-line tool that compresses and extracts archives without format-specific flags.
ouch is an MIT-licensed command-line tool that picks the format from the file name, covering tar, zip, gzip, xz and zstd without format-specific flags.
Keka
macOS file archiver for 7z, ZIP, TAR and more, with password protection.
Keka gives macOS users a graphical 7z and ZIP archiver with encryption and split archives, but it does not run on Linux.
7-Zip-zstd
Build of 7-Zip that adds Zstandard, Brotli, LZ4, LZ5 and Fast-LZMA2 compression.
7-Zip-zstd adds Zstandard, Brotli and LZ4 codecs to 7-Zip on Windows and Linux, but archives using them will not open in stock 7-Zip.
bsdtar (libarchive)
Command-line archivers built on libarchive that read and write tar, zip, cpio, ISO and more.
bsdtar reads many formats including zip, rar and ISO from one command-line tool, but writes fewer formats than it reads and does not produce 7z compression ratios.
XZ Utils
The standard command-line tool for creating and reading .xz files.
XZ Utils offers LZMA2 compression similar to 7z's on the command line, but compresses single files or streams rather than multi-file archives.
Also worth comparing
These listings name p7zip as their own alternative, so the relationship runs both ways.
dtrx
A command-line tool that extracts many archive formats with one consistent command.
p7zip brings 7-Zip's command-line tools to Linux and macOS, both creating and extracting archives, though its development has slowed compared with Windows 7-Zip.
ripunzip
A command-line tool that unzips ZIP files in parallel, including while downloading them from a URL.
p7zip extracts ZIP and 7z files on Linux and macOS from the command line and can also create archives, but it lacks parallel unzipping from a URL.
Similar software
Related functionality, not a direct replacement.
Zstandard
Meta's compression tool that hits near-zlib ratios at far higher speed, now used across Linux and modern filesystems.
The Unarchiver
macOS extractor that opens archive formats Finder cannot.
GNU Tar
The GNU command-line tool for creating, extracting, updating and listing tar archives.
zpaqfranz
Keep compressed, versioned archives of changing files.
