YAMS is under active development. Expect bugs and breaking changes. Wait for 1.0 for production use.

Content-addressed storage with deduplication, compression, full-text and vector search.

Features¶

Feature	Description
Content-addressed	SHA-256 hashing for immutable references
Deduplication	Rabin fingerprinting block-level dedupe
Search	FTS5 full-text + ONNX embedding vector search
Durability	WAL-backed, thread-safe, high-throughput
Interface	CLI and MCP server
Extensible	Plugin architecture

Platforms: Linux x86_64/ARM64, macOS x86_64/ARM64, Windows x86_64

brew install trvon/yams/yams
yams --version

# Linux/macOS
