What it is
MemoryCustodian is an open-source CLI that gives AI coding agents like Claude Code, Codex, and Gemini durable project memory stored as plain Markdown files inside your own git repo, instead of losing decisions the moment a chat window resets. It's free, self-hosted, and built specifically to stop agents from re-litigating settled architecture calls every session.

What you get free vs paid
Verdict
Pros
- Free and fully open source, no account or hosted service required
- Memory lives in plain Markdown tracked by git, so you can read, diff, and edit it like any other file
- A manifest routes agents to only the memory relevant to the current task instead of dumping everything into context
- Works across multiple agents, including Claude Code, Codex, and Gemini, rather than locking you into one
Cons
- Command-line only right now, no GUI, so setup takes more effort than a hosted memory product
- Memory quality depends on the agent or you actually writing good entries, it doesn't auto-summarize decisions on its own
- Young project, so expect rough edges and possible breaking changes
If you're already running agentic coding sessions and tired of re-explaining the same architectural decisions, this is a genuinely useful five-minute install, just don't expect a polished GUI.
