Fast and efficient content-defined chunking for data deduplication. Java implementation of FastCDC as library.

DedupBench is a benchmarking tool for content-defined chunking techniques used in data deduplication. It currently supports eleven unique CDC techniques and five different vector instruction sets.

Fast content-defined chunking in Go.

CDCZip is a deduplication filter meant for use as long range match finder preprocessor for use alongside other compression algorithms.

Find (partial content) duplicate files.

A Rust library for Content-Defined Chunking (CDC).

Print FastCDC rolling hash chunks and checksums.

Synclet is a content-defined, chunk-based file synchronization and backup tool that detects and syncs only the actual changes—efficiently, intelligently, and reliably.

Open-source, self-hostable file sync for people and AI agents, with a Rust daemon and CLI, native macOS Finder integration, scoped sharing, and S3-compatible storage.

The CAVS Hub command-line client — wire Git LFS to content-defined, deduplicated transfers so only changed bytes travel on push/pull.

Open-source toolkit for lossless, reference-based reconstruction of large binary artifacts using deterministic CDC and compact SBD1 seeds.

Clojure implementation of Rabin-Karp rolling hash and chunker

Coldkeep is a correctness-first, content-addressed cold-storage engine with deterministic restore, staged integrity verification, safe garbage collection, deduplication, transform-aware packed storage, stable storage semantics, and a reusable engine/catalog core. v1.x is complete; v2.x focuses on local-first productization.
