m3-memory vs initrunner
m3-memory: M3 Memory provides persistent, local memory for MCP agents using SQLite, hybrid retrieval, and optional cross-device sync. It stores facts, decisions, and preferences across sessions, with contradiction handling and knowledge graph features. It works offline and integrates with Claude Code, Gemini CLI, and other MCP-compatible agents.; initrunner: InitRunner lets you define an agent in one YAML file, chat with it, run it autonomously, and deploy it as a daemon triggered by cron, file changes, webhooks, or Telegram messages. It supports multiple execution modes, built-in memory, cost controls, multi-agent orchestration, and security features. Built on PydanticAI.

TL;DR
Choose m3-memory if…Coding agents like Claude Code or Gemini CLI need persistent memory across sessions
Choose initrunner if…Automated code review: set up a daemon that reviews pull requests or file changes.
