rms-memory-mcp vs Perenna

Q: Which is better, rms-memory-mcp or Perenna?

By GitHub stars, Perenna has more community adoption, but the best choice depends on your specific use case.

rms-memory-mcp: RMS Memory MCP provides persistent, local-first memory for AI coding agents, centralizing architectural decisions and user preferences in a structured Markdown vault. It bridges the context gap between different AI IDEs, preventing repetitive re-explanation and maintaining a unified knowledge base for development projects.; Perenna: Perenna provides a lightweight, Git-backed permanent memory solution for various AI agents, enabling them to share durable memories without vendor lock-in. It stores human-readable Markdown in a Git repository and uses a local Vexor index for retrieval, ensuring memory persistence across different agents and machines.
