a C\C++ library and command-line tools for Diff & Patch between binary files or directories(folder); cross-platform; runs fast; create small delta/differential; support large files and limit memory requires when diff & patch.

Fast and portable delta encoding for .NET in 100% safe, managed code.

Fast delta encoding in python using xdelta3

Heavily optimized .NET Core vcdiff library

Development continues in Codeberg ------ Decompressor for delta encoding VCDIFF (RFC-3284) -- xdelta3 compatible.

Xdelta for Go

A modified implementation of VCDIFF used by the latest COD FastFiles for data compression.

Open VCDiff implementation in .NET Core

Efficient and reliable update system for small to big set of files

Asynchronous native addon for Node.js for generation and application of patches in VCDIFF format using the Xdelta algorithm

Pure rust (no unsafe) vcdiff decoder / (encoder in the future)

An implementation of the VCDIFF (RFC3284) encoder that uses Tichy's string-to-string correction algorithm

Auto-managing file-level delta compression for OS images. Computes per-file VCDIFF/text-diff patches between filesystem snapshots; pluggable storage and encoder backends. Reconstructs image from base and delta.

VCDiff implementation in javascript (partially compliant with RFC 3284)
