LZHAM is a general purpose lossless data compression library that borrows many ideas from LZMA, but purposely makes several key tradeoffs that favor decompression speed over compression ratio. LZHAM's compression ratio is typically within .5% of LZMA, but decompresses 2-3 times faster. LZHAM's compressor is heavily threaded in a way that does not sacrifice compression ratio. The decompressor supports streaming and memory to memory decompression, and is designed to be particularly fast on embedded devices, handhelds, and game console platforms.

excat is a simple tool that auto-detectd (potentially nested) compressed file formats and decompresses any combination of them using libarchive, thus unifying zcat, bzcat, lzcat, xzcat, etc. in a single (static, if you need it) binary. It may act as a drop-in replacement for any *cat.

Lunzip is a decompressor for lzip files. Its small size makes it well suited for embedded devices or software installers that need to decompress files but do not need compression capabilities. Lunzip is able to decompress any lzip file using as little memory as 50 kB.

lxz aims to create xz-compatible compressed files, utilizing multiple threads and liblzma. It was forked from lbzip2-0.23 and inherited the same internal structure. It supports compression only (basic features), and will lose its raison d'etre as soon as xz itself gets multithreading support.

compressible is a command line utility to test whether compressing a given file with bzip2 is likely to result in space savings greater than a given threshold. It does bzip2 compression on samples taken from several locations in the file.

lzo-java is a Java port of liblzo2, a portable lossless data compression library. It provides block and stream interfaces to the lzo1x, lzo1y, and lzo1z algorithms, and it can handle raw and lzop file formats. The implementation is designed for high performance reading and writing, and simplicity of integration. It is integrated with Hadoop for high performance, and transparent compression is included.

Pipa reads data from stdin and does various things with it: rotates by time interval / output file size; compresses it (gz, bz2, lzo, xz); names the output file with strftime(); splits it intelligently when given info about the file structure (newlines / PCAP); calls a user command on the finished output file; passes it to stdout (like tee); and more.
