## Which one, for what

### claude-mem (C)

Good for: Session memory for one developer's coding agents, recalled by staged MCP search, with optional hosted sync across machines.

Ahead on:
- Reliability, 85 against 65
- Schema & documentation, 84 against 55
- Agent ergonomics, 74 against 60
- Security & auth, 50 against 37

Also in its favour:
- Runs on your own machine

Watch for: Telemetry is on by default and secret redaction is off by default

### Hy Memory (C)

Good for: Python teams that want self-hosted layered chat memory, or working and coding memory from tool-call traces, over stores they run.

Ahead on:
- Payments & pricing, 60 against 20
- Transparency & trust, 63 against 46

Also in its favour:
- No key needed to call it
- Free to start without a card
- No incidents deducted, where claude-mem loses 6 points for them

Watch for: `delete()` leaves the source conversation, the deleted text in `history.db` and extraction prompts in `cache.db`, and can reactivate a superseded fact

## Verdicts

**claude-mem.** Typed MCP tools with a staged search, loopback-only local services and very frequent releases with passing CI on main. 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.

**Hy Memory.** An Apache-2.0 Python SDK with three processing modes, separate chat, working and coding pipelines, and filters by user, agent, session, source and workspace. Deletion does not stick everywhere. `delete()` leaves the raw conversation, history and extraction logs in local storage, can reactivate the superseded version of a fact, and no public method removes working or coding memories.

## Before you call either

### claude-mem

1. 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.
2. Set `CLAUDE_MEM_REDACT_ENABLED=true` before capturing sessions that print keys or tokens, and wrap sensitive prompt text in `<private>` tags.
3. Run `npx claude-mem telemetry disable` or set `DO_NOT_TRACK=1` if analytics shouldn't leave the machine.
4. 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.
5. Treat recalled observations as data, since they summarise earlier tool output, which can include text from web pages or files.

### Hy Memory

1. Pass `user_id` on every `add()` and `user_ids` on every `search()`. Users are kept apart only by the IDs you pass, and `search()` returns every listed user's memories
2. Choose the mode before writing. `lite` makes no LLM calls and stores raw text. `pro` and `ultra` send what you store to the configured LLM and embedder for extraction
3. Don't rely on `delete()` to erase a fact. The raw conversation, `history.db` and `cache.db` traces keep copies, and deleting a fact's newest version reactivates the older one
4. Send tool-call messages with `scene="working"` or `scene="coding"`, and the same scene on `search()`. Without tool messages a write falls back to chat memory
5. Keep `python -m hy_memory.server` on 127.0.0.1. It has no authentication and allows any web origin
