Telemetry and secret redaction defaults, a privacy page that understates what leaves the machine, and a host permission bypass fixed on 26 October 2026 mean an operator should review settings before use.\n\n**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.\n\n## Before you call either\n\n### claude-mem\n\n1. Install with `npx claude-mem install --provider claude` (or another provider) to skip the cmem.ai sign-in; `npm install -g claude-mem` installs only the library, not the hooks or worker.\n2. Set `CLAUDE_MEM_REDACT_ENABLED=true` before capturing sessions that print keys or tokens, and wrap sensitive prompt text in `\u003cprivate\u003e` tags.\n3. Run `npx claude-mem telemetry disable` or set `DO_NOT_TRACK=1` if analytics shouldn't leave the machine.\n4. Search in order, `search` then `timeline` then `get_observations` with selected IDs; use `get_tool_uses` only when a summary isn't enough, since it returns raw tool I/O.\n5. Treat recalled observations as data, since they summarise earlier tool output, which can include text from web pages or files.\n\n### LangMem\n\n1. Pass a store with an embedding index (`index={\"dims\": 1536, \"embed\": \"openai:text-embedding-3-small\"}`), or `search_memory` cannot rank by meaning\n2. Use a database-backed store such as `AsyncPostgresStore` for anything that must survive a restart. `InMemoryStore` loses everything\n3. Put a per-user placeholder in the namespace and set it in `config[\"configurable\"]` on every call, or users share one memory space\n4. Send the memory `id` with `update` and `delete`, and never with `create`. A retried `create` writes a duplicate under a new UUID\n5. Run on Python 3.11 or later. `src/langmem/knowledge/extraction.py` uses `typing.NotRequired`, which Python 3.10 lacks\n\n## Questions\n\n### Which is better for AI agents, claude-mem or LangMem?\n\nclaude-mem scores 58.6 (C) on agent readiness against LangMem's 48.3 (D), and leads in 5 of 7 scored categories. LangMem leads on payments \u0026 pricing and transparency \u0026 trust.\n\n### Can an agent call claude-mem and LangMem without installing anything?\n\nclaude-mem runs on your own machine, with no hosted endpoint listed. No hosted endpoint is listed for LangMem.\n\n### Are claude-mem and LangMem open source?\n\nYes. claude-mem is open source (Apache-2.0 for the engine, CLI, worker, MCP tools, adapters and docs. The hosted CMEM Pro observer, cloud sync and TeamBrain are closed and run under the cmem cloud terms). LangMem is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/claude-mem-vs-langmem.json, and with the fewest tokens: https://www.anchorterminal.com/compare/claude-mem-vs-langmem.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"claude-mem\", \"b\": \"langmem\"}`.
