Yams

YAMS, short for Yet Another Memory System, is local first, persistent memory for code, documents and applications. It stores content with content addressed storage and retrieves it through text, vector, graph and grep search, giving a developer or an AI agent a searchable memory that stays on the user's own machine. A user installs it with Homebrew, APT, DNF, pacman, Docker or a Windows MSI, runs init, adds content with tags and searches it from the command line. For MCP compatible developer tools, running the serve command exposes YAMS as an MCP server so an assistant can read and write that memory. Other documented areas include peer to peer corpus sync, benchmarks, runtime path and configuration policy, and a roadmap and newsletter. The project says plainly that it is experimental and pre 1.0, and that it may change without compatibility guarantees. It is licensed under GPL 3.0 or later, with source on GitHub and a self hosted mirror, plus a Discord community. There is no charge for the software. The site lists no paid plans or prices.
