Fast and efficient content-defined chunking for data deduplication. Java implementation of FastCDC as library.
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.
Print FastCDC rolling hash chunks and checksums.
A Rust library for Content-Defined Chunking (CDC).
Synclet is a content-defined, chunk-based file synchronization and backup tool that detects and syncs only the actual changes—efficiently, intelligently, and reliably.
Ship a search index to a device as signed, content-addressed bundles: fail-closed Ed25519 verification, FastCDC chunking so the next release downloads only the chunks that changed, then FAISS + BM25 rank fusion locally. Python. 309 tests, 98% coverage.
Clojure implementation of Rabin-Karp rolling hash and chunker
Open-source toolkit for lossless, reference-based reconstruction of large binary artifacts using deterministic CDC and compact SBD1 seeds.
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.
A FUSE-based filesystem implementing content-defined chunking and deduplication in Rust.
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.
Eliminating storage redundancy at the sub-file level. A zero-copy deduplication engine in Rust, powered by Content-Defined Chunking (FastCDC) and BLAKE3, with instant browser WASM execution.
