What Is claude-mem?
claude-mem is an open-source, community-built plugin that gives Claude Code persistent memory across sessions — it silently records compressed, categorized observations after every tool call, storing them in a local SQLite database with Chroma vector search, then injects relevant context back into future sessions automatically. Built by developer Alex Newman and hosted on GitHub, it has grown into one of the most popular Claude Code community plugins, reaching over 46,000 GitHub stars, 3,500 forks, and 92 contributors across 223 releases as of its v12.0.0 release.
Its technical approach is genuinely well-suited to the problem it solves: rather than dumping raw tool output into a growing context file, it uses Claude's own agent SDK to generate semantic summaries of what happened during a session, then stores those summaries locally rather than in the cloud — meaningful for developers who don't want session history leaving their machine. Five lifecycle hooks (SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd) handle the capture automatically, and memory works across projects, so a question like "what did we change on the API last week?" can be answered even from an unrelated current session.
Installation is a single command (npx claude-mem install), making it accessible to any Claude Code user wanting persistent project memory without building a custom solution themselves. See our Coding tools directory for more on the broader Claude Code ecosystem.

Frequently Asked Questions
Is claude-mem an official Anthropic product?
No, it’s a community-built, open-source plugin for Claude Code created by developer Alex Newman.
Where does claude-mem store data?
Locally on disk in a SQLite database with Chroma vector search, not in the cloud.
How do I install claude-mem?
With a single command: `npx claude-mem install`.
Does claude-mem work across different projects?
Yes, memory persists across projects, so questions about past work can be answered from an unrelated current session.
Our Take
claude-mem's local-first, automated approach to persistent memory is a genuinely well-engineered solution to a real gap in Claude Code's default session-based workflow.
Its rapid community adoption — tens of thousands of GitHub stars — reflects how many developers were missing exactly this capability.
