Tree Ring Memory is a framework-agnostic, local-first memory lifecycle layer for AI agents that prevents memory from becoming raw transcript sludge.
It uses a ring-based aging model to distill, compress, and preserve information, ensuring that durable truths and lessons remain accessible while ephemeral data is managed or forgotten.
- 01
Ring-based memory lifecycle (cambium, outer, inner, heartwood, scar, seed)
- 02
Local-first SQLite/FTS storage with no required cloud service
- 03
Deterministic, LLM-free memory consolidation and maintenance
- 04
Source-linked evidence and DOX/Revolve synchronization adapters
- 05
Explicit memory audit, redaction, and expiration controls
Open Source
Free and open-source with no required cloud services or subscriptions.
Best for
Developers who need a portable, inspectable, and privacy-focused memory layer that keeps AI agent context clean, organized, and relevant 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, multi-agent identities, idempotent worker writes, project-local harness activation, and verified release bootstrapping.
