Persistent memory for Claude Code: automatically captures tool-usage observations during sessions, compresses them into semantic summaries, and injects relevant context into future sessions. Stores memories in a local SQLite database with layered progressive-disclosure retrieval, a mem-search skill, privacy tags for excluding sensitive content, and a real-time web viewer at localhost:37777. Installs with one command and runs without manual intervention.
- Remember project context and decisions across coding sessions
- Search past notes and memories using natural language queries
- Compress and manage session history to keep context efficient
Persistent context is the most requested enterprise Claude Code capability - this is the most battle-tested open-source solution, with 86k GitHub stars and active daily development.

2026-04-02: LIMITATION: AGPL-3.0 license creates commercial licensing friction — companies must disclose source or obtain a commercial license. Spawns a background HTTP server on port 37777.
Things to check
- npm install -g claude-mem installs the SDK/library only - it does not register the plugin hooks or start the worker service; use npx claude-mem install or the in-app /plugin commands. Runs a background worker and stores all memories in a local SQLite database; restart Claude Code after installing.
