Curator's take

Pick it when memory auditability and reversibility matter — you want to branch an agent's memory, roll back a bad write, or trace the provenance of every fact, and you're fine running MatrixOne underneath. Overkill if you just need a simple recall store (memmachine, memmolt) or fully-local files (memanto) — the versioning engine and DB dependency are the cost. Young project, Apache-2.0.

Memoria

The World's First Git for AI Agent Memory

Snapshot · Branch · Merge · Rollback — for memory, not code.

Git made code safe to change. Memoria makes memory safe to change.

Quick Start · Why Memoria · Research · See It in Action · API Reference · Architecture · Development · Citation

Overview

Memoria is a persistent memory layer for AI agents with Git-level version control. Every memory change is tracked, auditable, and reversible — snapshots, branches, merges, and time-travel rollback, all powered by MatrixOne's native Copy-on-Write engine.

🔀 Git for Memory

Zero-copy branching, instant snapshots, point-in-time rollback — version control for every memory mutation

🔍 Semantic Search

Vector + full-text hybrid retrieval finds memories by meaning, not just keywords

🛡️ Self-Governing

Auto-detects contradictions, quarantines low-confidence memories, maintains audit trails

🔒 Private by Default

Local embedding model option — no data leaves your machine

🧠 Cross-Conversation

Preferences, facts, and decisions persist across sessions

📋 Full Audit Trail

Every memory mutation has a snapshot + provenance chain

Supported Agents

MemMachine

Long-term memory layer for AI agents — episodic (graph), profile (SQL) and working memory behind Python/TS SDKs, REST and MCP; ships LangChain, LangGraph, CrewAI and LlamaIndex integrations.

Why it fitsBoth are long-term memory layers for agents; memmachine splits episodic-graph/profile-SQL/working tiers, Memoria adds Git-style snapshot/branch/merge/rollback and contradiction quarantine on MatrixOne's copy-on-write engine.

memory-os

A 7-layer memory operating system for Hermes Agent: Qdrant vectors, structured facts, fabric recall, an auto-curated wiki, and surgical context injection.

Why it fitsBoth are persistent agent memory layers; memory-os is a 7-layer Qdrant-based memory OS, Memoria is a Rust versioned store with time-travel rollback and provenance chains.

hindsight

Agent memory that learns, not just recalls: retain/recall/reflect API over Postgres, SOTA on LongMemEval. Self-host via Docker with UI; Python/TS clients, any LLM provider.

Why it fitsBoth add governance to agent memory; hindsight is retain/recall/reflect over Postgres, Memoria is version-controlled 'Git for memory' with auditable snapshots.
