Tree Ring Memory is a framework-agnostic, local-first memory lifecycle layer for AI agents that prevents transcript buildup by organizing memory into rings based on age and importance.

It uses a Rust-native CLI and SQLite storage to manage, distill, and compress agent knowledge into durable, inspectable records.
- 01
Ring-based memory aging model (cambium, outer, inner, heartwood, scar, seed)
- 02
Local-first SQLite/FTS storage with no cloud dependency
- 03
Deterministic, LLM-free memory consolidation and maintenance
- 04
Source-linked evidence tracking and DOX/Revolve synchronization adapters
- 05
Explicit audit, redaction, and multi-agent coordination controls
Open Source
Free and open-source with no required cloud services or subscriptions.
Best for
Developers who need a portable, privacy-focused, and inspectable memory layer that keeps AI agent context organized, relevant, and clean over time.
Not ideal for
Use cases requiring distributed locking, network-filesystem coordination, or cross-host synchronization, as the tool is limited to concurrent processes on a single host.
A robust, highly performant tool for engineering teams seeking a deterministic way to manage agent memory that respects user privacy and avoids the pitfalls of bloated chat transcripts.
Recent versions (v0.11-v0.15) introduced Rust-native terminal onboarding, same-host multi-agent identities, idempotent worker writes, project-local harness activation with receipt-backed proof, and verified release bootstrapping.
