7-Zip
7-Zip suits anyone who wants a no-cost archiver with AES-256 and open source code. It also offers volumes, self-extracting archives and a command line. The catch: it cannot create RAR or Zstandard archives, and its documentation describes recovery of damaged archives as a manual job.
NanaZip
NanaZip suits Windows 10 and 11 users who want the 7-Zip feature set with a File Explorer context menu, ARM64 support and extra codecs such as Zstandard. It costs nothing and the code is public. The catch: it has no macOS or Linux builds, and its pages document few features directly, so most of the feature set is documented by 7-Zip.
