## Which one, for what

### Graphicle (B)

Good 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
- Security & auth, 69 against 45
- Maintenance & community, 48 against 15
- Transparency & trust, 68 against 59

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)

Good 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

1. Call `recall_project` with a `max_tokens` budget, then `read_project_source` with the cited id and byte offset to continue a cut excerpt
2. Use `query_graph`, `get_neighbors` and `shortest_path` for structure questions, and pass `repo` to reach another synced project
3. Treat proposed memories as drafts. They are not served until a person approves them in `graphicle open` under Memory
4. Ask the user before running `graphicle setup`, which edits agent settings, AGENTS.md and Git hooks, and use `graphicle disconnect` to undo it
5. Over HTTP send the key as `Authorization: Bearer`, never in the URL, and on 429 wait for the Retry-After reset

### LangMem

1. Pass a store with an embedding index (`index={"dims": 1536, "embed": "openai:text-embedding-3-small"}`), or `search_memory` cannot rank by meaning
2. Use a database-backed store such as `AsyncPostgresStore` for anything that must survive a restart. `InMemoryStore` loses everything
3. Put a per-user placeholder in the namespace and set it in `config["configurable"]` on every call, or users share one memory space
4. Send the memory `id` with `update` and `delete`, and never with `create`. A retried `create` writes a duplicate under a new UUID
5. Run on Python 3.11 or later. `src/langmem/knowledge/extraction.py` uses `typing.NotRequired`, which Python 3.10 lacks
