Which one, for what
Best for A developer who wants one local tool that gives Claude Code, Codex or Cursor both code structure and project memory with citations.
Ahead on
- Reliability, 63 against 32
- Schema & documentation, 83 against 55
- Agent ergonomics, 86 against 66

Also in its favour
- Runs on your own machine
- Free to start without a card
Watch for
One release, v0.1.0 on 14 October 2026, from a repository created that day
LangMem D
Best for Teams already on LangGraph that want memory tools and background extraction over a store they run.
Also in its favour
- No key needed to call it
Watch for
The newest PyPI release, 0.0.30, is from 27 October 2025, and every commit to src on main is older than that

Verdicts
Graphicle
One local program gives a coding agent a code graph and project memory through 25 typed, annotated MCP tools that return cited excerpts within a token budget, with agent-written memories held for human approval. It is one day old at version 0.1.0, its SDKs are not on any registry, and the licence and advisory check fails on main.
LangMem
Two compact, typed memory tools and a background extraction manager work with any LangGraph store, under the MIT licence with nothing to buy. The newest PyPI release, 0.0.30, dates from 27 October 2025. The repository has no changelog, tags or test workflow, and 23 of 54 open issues have no reply.
Before you call either
Graphicle
- Call
recall_projectwith amax_tokensbudget, thenread_project_sourcewith the cited id and byte offset to continue a cut excerpt - Use
query_graph,get_neighborsandshortest_pathfor structure questions, and passrepoto reach another synced project - Treat proposed memories as drafts. They are not served until a person approves them in
graphicle openunder Memory - Ask the user before running
graphicle setup, which edits agent settings, AGENTS.md and Git hooks, and usegraphicle disconnectto undo it - Over HTTP send the key as
Authorization: Bearer, never in the URL, and on 429 wait for the Retry-After reset
LangMem
- Pass a store with an embedding index (
index={"dims": 1536, "embed": "openai:text-embedding-3-small"}), orsearch_memorycannot rank by meaning - Use a database-backed store such as
AsyncPostgresStorefor anything that must survive a restart.InMemoryStoreloses everything - Put a per-user placeholder in the namespace and set it in
config["configurable"]on every call, or users share one memory space - Send the memory
idwithupdateanddelete, and never withcreate. A retriedcreatewrites a duplicate under a new UUID - Run on Python 3.11 or later.
src/langmem/knowledge/extraction.pyusestyping.NotRequired, which Python 3.10 lacks
