Why free?

Monetising a memory layer that reads your code is the wrong trade. Munin runs local. Your corpus stays on your disk. No network call to bill against, no dashboard to gate your data, no usage cap to engineer around.

Will you add a paid tier later?

Only if something needs paid-tier distribution (e.g. a hosted team view over aggregated friction reports). The core (local ingestion, learning, actions) stays free.

Is there an enterprise version?

No. One binary, one tier. If you need enterprise SSO or audit logs, Munin is not the right tool. Your agents produce the audit trail; Munin watches it.

Can I run this air-gapped?

Yes. Munin is a local Rust binary with no outbound network calls. Build from source once, and it runs offline. Nothing needs an internet connection after install.

What data does Munin read?

Session transcripts under ~/.claude/, ~/.codex/, .munin/journal/, and any paths you add. It does not read your source code repositories. Only the session logs your agents write while working in them.

How big does .munin/ get?

Typical repos with 6 months of session history: 40 to 120 MB. Munin dedupes and compacts on journal promotion. Decay thresholds drop stale evidence.

Install and go.
