Snappy - Port of Snappy to Java

•    Java

This is a rewrite (port) of Snappy writen in pure Java. This compression code produces a byte-for-byte exact copy of the output created by the original C++ code, and extremely fast.

LZF Compressor- High-performance, streaming/chunking Java LZF codec, compatible with standard C LZF package

•    Java

LZF-compress is a Java library for encoding and decoding data in LZF format, written by Tatu Saloranta. LZF alfgorithm itself is optimized for speed, with somewhat more modest compression. Compared to the standard Deflate (algorithm gzip uses) LZF can be 5-6 times as fast to compress, and twice as fast to decompress. Compression rate is lower since no Huffman-encoding is used after lempel-ziv substring elimintation.

zlib.js - compact zlib, deflate, inflate, zip library in JavaScript

•    Javascript

compact zlib, deflate, inflate, zip library in JavaScript

XZ for Java

•    Java

This aims to be a complete implementation of XZ data compression in pure Java. Single-threaded streamed compression and decompression and random access decompression have been fully implemented. Threading is planned but it is unknown when it will be implemented.

zlib - A Massively Spiffy Yet Delicately Unobtrusive Compression Library

•    C

zlib is a general purpose data compression library. All the code is thread safe. It is ported to different programming languages like Java, CSharp, Python and Perl.

lz4-java - LZ4 compression for Java

•    C

LZ4 compression for Java, based on Yann Collet's work available at http://code.google.com/p/lz4/. This library provides access to two compression methods that both generate a valid LZ4 stream fast scan (LZ4) and high compression (LZ4 HC). The streams produced by those 2 compression algorithms use the same compression format, are very fast to decompress and can be decompressed by the same decompressor instance.

7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard

•    C

Zstandard v1.3.7 is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder. Brotli v.1.0.7 is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.

lzfse - LZFSE compression library and command line tool

•    C

This is a reference C implementation of the LZFSE compressor introduced in the Compression library with OS X 10.11 and iOS 9. LZFSE is a Lempel-Ziv style data compression algorithm using Finite State Entropy coding. It targets similar compression rates at higher compression and decompression speed compared to deflate using zlib.

Redisson - Redis based In-Memory Data Grid for Java

•    Java

Redisson - distributed Java objects and services (Set, Multimap, SortedSet, Map, List, Queue, BlockingQueue, Deque, BlockingDeque, Semaphore, Lock, AtomicLong, Map Reduce, Publish / Subscribe, Bloom filter, Spring Cache, Executor service, Tomcat Session Manager, Scheduler service, JCache API) on top of Redis server. Rich Redis client.

pako - high speed zlib port to javascript, works in browser & node.js

•    Javascript

zlib's test is partially affected by marshalling (that make sense for inflate only). You can change deflate level to 0 in benchmark source, to investigate details. For deflate level 6 results can be considered as correct.

Info ZIP - Compressor Archiver Utilities

•    C

Info-ZIP's purpose is to provide free, portable, high-quality versions of the Zip and UnZip compressor-archiver utilities that are compatible with the DOS-based PKZIP.

Zstandard - Fast real-time compression algorithm

•    C

Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder. It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set.

HU01 Decompression

Hotmail's DeltaSync protocol uses custom compression scheme known as hm-compression or HU01. It is very similar to DEFLATE encoding, which is standardized as RFC 1951, but the bit stream format is different. Earlier work on decompressing these streams was published by Daniel P...

SHARC - Fastest lossless compression algorithm

•    C

SHARC is an extremely fast lossless dictionary-based compression algorithm. It is capable of an unprecedented compression speed of more than 500 MB/s per core on modern Intel CPUs ! It is scalable on multi core/multi CPU, developed in pure C99, and easily portable on many platforms.

compress - Optimized compression packages

•    Go

This package is based on an optimized Deflate function, which is used by gzip/zip/zlib packages. It offers slightly better compression at lower compression settings, and up to 3x faster encoding at highest compression level.

zlib-ng - zlib replacement with optimizations for "next generation" systems.

•    C

The motivation for this fork was due to seeing several 3rd party contributions containing new optimizations not getting implemented into the official zlib repository. Mark Adler has been maintaining zlib for a very long time, and he has done a great job and hopefully he will continue for a long time yet. The idea of zlib-ng is not to replace zlib, but to co-exist as a drop-in replacement with a lower threshold for code change.
