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.

pigz - A parallel implementation of gzip for modern multi-processor, multi-core machines

•    C

pigz, which stands for parallel implementation of gzip, it compresses using threads to make use of multiple processors and cores. The input is broken up in to 128 KB chunks with each compressed in parallel. The individual check value for each chunk is also calculated in parallel. The compressed data is written in order to the output, and a combined check value is calculated from the individual check values.

JZlib - Zlib in Java

JZlib is a re-implementation of zlib in pure Java. JZlib can inflate data, which is deflated by zlib and JZlib can generate deflated data, which is acceptable and is inflated by zlib. JZlib supports all compression level and all flushing mode in zlib.

node-unzip - node.js cross-platform unzip using streams

•    Javascript

Streaming cross-platform unzip tool written in node.js. Unzip provides simple APIs similar to node-tar for parsing and extracting zip files. There are no added compiled dependencies - inflation is handled by node.js's built in zlib support. Unzip is also an example use case of node-pullstream.

SharpZipLib - Compression Library in CSharp

•    CSharp

#ziplib (SharpZipLib, formerly NZipLib) is a Zip, GZip, Tar and BZip2 library written entirely in C# for the .NET platform. It is implemented as an assembly (installable in the GAC), and thus can easily be incorporated into other projects (in any .NET language).

Zathura - Document Viewer

•    C

zathura is a highly customizable and functional document viewer based on the girara user interface library and several document libraries. zathura is capable of exporting images and attachments, opening encrypted documents and printing them. You can search through the document or browse its index or checkout the document meta information.

sebsauvage-ZeroBin

•    Javascript

A minimalist, opensource online pastebin where the server has zero knowledge of pasted data. Data is encrypted/decrypted in the browser using 256 bits AES. Data compressed and encrypted in the browser before sending to server. Server has zero knowledge of data being stored. Your data is safe even in case of server breach or seizure.

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.

Postmill - Social link aggregator with voting and nested comments

•    PHP

Postmill is a free, web-based, social link aggregator with voting and threaded comments. It is built on the Symfony framework. Any similarities between this software and that of a large community symbolised by an alien logo are purely coincidental.

flate2-rs - DEFLATE, gzip, and zlib bindings for Rust

•    C

A streaming compression/decompression library DEFLATE-based streams in Rust. This crate by default uses the miniz_oxide crate, a port of miniz.c to pure Rust. This crate also supports other backends, such as the widely available zlib library or the high-performance zlib-ng library.

zlibnet - c# zlib wrapper library

•    CSharp

zlibnet - c# zlib wrapper library

HTTP Compression Library for Heavy Load Web Server

Deflater is a HTTP Compression Library, supporting Deflate (RFC 1950, RFC 1951) and GZip (RFC 1952). It is designed to encode and compress HTML content at once.

DeflateLib

The implementation of RFC 1951 -- DEFLATE Compressed Data Format Specification version 1.3 (also RFC 1950 ZLIB and 1952 GZIP). It's written in managed C#. The project has basic compression algorithm implementation as it's described in the RFC.

lizard - Lizard (formerly LZ5) is an efficient compressor with very fast decompression

•    C

Lizard library is based on frequently used LZ4 library by Yann Collet but the Lizard compression format is not compatible with LZ4. Lizard library is provided as open-source software using BSD 2-Clause license. The high compression/decompression speed is achieved without any SSE and AVX extensions. The following results are obtained with lzbench and -t16,16 using 1 core of Intel Core i5-4300U, Windows 10 64-bit (MinGW-w64 compilation under gcc 6.2.0) with silesia.tar which contains tarred files from Silesia compression corpus.

ezlib - Erlang zlib NIF library optimized for streaming

•    Erlang

Based on zlib FAQ thread safety of the library can be achieved by meeting several conditions. The most important being the fact that you should only operate on any given zlib stream from a single thread at a time. In erlang this means that you need to operate on a ezlib session from the same process that created it. In case you access the same stream from multiple processes you will get an error when calling process/2.The default values for window_bits and memory_level are 15 and 8 so for this values the default required memory for deflate is 256 KB and for inflate is 44 KB.

minizlib - A smaller, faster, zlib stream built on http://npm

•    Javascript

A tiny fast zlib stream built on minipass and Node.js's zlib binding.This module was created to serve the needs of node-tar v2. If your needs are different, then it may not be for you.

gzip-size - Get the gzipped size of a string or buffer

•    Javascript

Returns a Promise for the size.Returns the size.
