Wontopos (Tablet 2) |
Managed long-term memory API with no lexical matching and no language model in the retrieval path, so recall is deterministic and language-agnostic: paper-reported 95.7% on LongMemEval-S and 95.2% mean recall@5 across 70 store-and-query language pairs where BM25 scores 19.0%, plus 91.4% recall@5 on caption-free photos across 14 languages. BEAM-1M 67.5%, with the harness and per-question records published. |

sqlite-graph-memory |
Graph RAG on SQLite for a single-user agent: vector retrieval for entry points, hand-curated Obsidian [[wikilinks]] as the graph (no entity-extraction pass, no graph database), a cross-encoder rerank, and a zero-token per-turn memory ledger — three Python files, one SQLite file, stdlib driver. Pilot, MIT. |

RCLL (fleet-memory) |
Self-hosted shared memory for a team of AI agents: topic-scoped rooms over one store, hierarchical L0–L3 depth, Postgres + pgvector, MCP. The read path never invokes a language model, so a recall costs CPU and zero model tokens. Publishes its own LoCoMo ablation of what one pooled store costs against ten private ones, including the arms that lose. Fork of Hindsight, MIT. |

Verified Memory Vault |
Self-checking Obsidian vault for AI agent memory: plain-Markdown storage with a hygiene self-audit (memory_check) and a git pre-commit guard against bulk deletions (memory_guard); no database or server required. |
|
 |
 |
| 2026-08 |
kgai |
Decision memory for AI coding teams: an immutable, append-only decision log that syncs across a team over an S3 bucket you own, no server in between. Content-addressed events from parallel writers cannot produce a textual conflict. Superseded decisions and rejected approaches stay queryable with the reason they were dropped. Local-first, MIT. |
|
 |
 |
| 2026-08 |
OpenViking |
Self-evolving context database for AI agents that unifies agent memory, knowledge RAG, and reusable skills behind one storage/retrieval layer, with an MCP server for cross-session read/write. |

 |
 |
| 2026-07 |
deja |

|
 |
 |
| 2026-07 |

|
|
 |
| 2026-06 |
projectmem |
Local-first, event-sourced memory + judgment layer for AI coding agents (Claude Code, Cursor, Antigravity, Codex): an append-only, plain-text event log of issues, failed attempts, fixes, and decisions, re-injected via MCP so the agent starts experienced — plus a deterministic pre-commit gate that warns before it repeats a previously failed fix. 100% local, MIT, with cross-project library memory and a cross-project dashboard. |
 |
 |
 |
| 2026-06 |
kaeru |
Local-first cognitive memory for any LLM agent over MCP: a bi-temporal typed knowledge graph (CozoDB / RocksDB) giving cross-session and multi-agent continuity via episodes, provenance chains, and consolidated outcomes — a single Rust binary, with an optional shared cloud tier for teams. |
|
 |
 |
| 2026-06 |
TeleMem |
Long-term and multimodal memory for agentic AI — a drop-in replacement for Mem0 with character-isolated memory profiles, LLM-based semantic deduplication, video memory with ReAct-style QA, an MCP server, and a fully local option (FAISS + Ollama/Qwen). |
 |
 |
 |
| 2026-06 |
AccInt |
Local-first Work Model for AI agents: records commitments, actions, approval gates, outcomes, and reusable runtimes, then uses outcome-scored memory to predict and replay verified paths across Claude Code, Codex, OpenCode, and Cursor via MCP. |

Dakera |
Self-hosted AI agent memory server scoring 87.8% on the LoCoMo benchmark. Features decay-weighted vector recall, hybrid BM25+HNSW retrieval, 83 MCP tools, and a knowledge graph layer — all in a single Rust binary with RocksDB persistence and zero external LLM dependencies. |

Mnemoverse |
Managed persistent memory API for AI agents over MCP: one API key or OAuth gives Claude Code, Cursor, VS Code, Windsurf and ChatGPT the same memory. Mnemoverse scores importance on write, links concepts through Hebbian associations tuned by a Rescorla-Wagner update, re-ranks recall from reported outcomes, and consolidates with HDBSCAN plus Von Restorff protection. Open-source MCP server and Python SDK (MIT), managed engine, free tier. |
