Overview

0CompactMem provides persistent memory for Claude Code and other LLM agents using OS memory primitives like demand paging and mlock pinning. It stores memory in a single SQLite file and is MCP-native, allowing multiple agents to share the same memory.

Developers building multi-agent LLM systems that need efficient, shared persistent memory with OS-level control

Use cases

• Persistent memory for LLM agent sessions across restarts
• Shared memory context for multi-agent collaboration
• Efficient memory management using OS-level demand paging

Use cases

• Persistent memory for LLM agent sessions across restarts
• Shared memory context for multi-agent collaboration
• Efficient memory management using OS-level demand paging

Pros

• Leverages OS memory management (demand paging, mlock) for performance
• Single SQLite file simplifies storage and portability
• MCP-native design enables seamless multi-agent memory sharing

Cons

• Low community adoption (0 stars) suggests early-stage or niche tool
• Requires system-level configuration of OS primitives (swap, mlock)
• Potential complexity in tuning memory constraints for different workloads
