Memorix vs Plur
Two MCP servers from our memory ranking, compared on live data - updated nightly, never sponsored.
Bottom line · 2026-09-18
Memorix records significantly more monthly package installs (29,602 vs 7,596); both are actively maintained, with commits inside the last month.
How they differ in kind
Memorix focuses on: Local-first shared memory layer for AI coding agents. Plur focuses on: Persistent, open memory for AI agents - local-first, zero-cost, shared across MCP tools (Claude Code, Codex, Cursor, Hermes, OpenClaw).
What each one does
Memorix
Local-first shared memory layer for AI coding agents. One project memory system for Claude Code, Codex, CodeBuddy Code, Cursor, Windsurf, Copilot, Gemini CLI, OpenCode, Grok Build, OpenClaw, Hermes Agent, Oh-my-Pi, Pi, Kiro, Antigravity, Trae, DeepSeek Harness, WorkBuddy, and any MCP-capable agent.
From the project's README.
Plur
Persistent, open memory for AI agents - local-first, zero-cost, shared across MCP tools (Claude Code, Codex, Cursor, Hermes, OpenClaw). Your agent's memory is plain-text engrams you can read, correct, and delete - not weights you can't. Its 15 documented tools cover plur, learn.
From the project's README.

Extracted from each project's README - the tools each server hands your agent. A missing list means the README doesn't document one, not that no tools exist.

Quick answers
Is Memorix better than Plur?
Package installs favor Memorix: 29,602 monthly installs to 7,596. Plur still ranks #5 of 304 maintained memory servers. Data as of 2026-09-18; we haven't hands-on tested either.
Can I use Memorix and Plur together?
Yes - MCP clients accept multiple servers in one config, so you can enable both memory servers side by side. If their tools overlap, keep the one whose toolset fits to keep your agent's tool list lean.
