## 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.

Watch for: Setup uploaded the last 30 days of prompts to cmem.ai without asking from 15.2.0 until 15.8.3 (25 October to 2 November 2026)

### EverOS (B)

Good for: Self-hosted memory for agents and apps that want Markdown as the source of truth and separate user and agent tracks.

Ahead on:
- Schema & documentation, 89 against 84
- Payments & pricing, 40 against 20
- Transparency & trust, 71 against 46

Also in its favour:
- No key needed to call it
- No incidents deducted, where claude-mem loses 8 points for them

Watch for: The local HTTP server has no authentication and relies on binding to 127.0.0.1


## Why the edge

### Transparency & trust: EverOS +25

- claude-mem (46): Apache-2.0 engine with the hosted observer, sync and team functions reserved as closed, per docs/ip-boundary.md (25 of 30). SECURITY.md lists every route by which data leaves the machine, but the cmem.ai privacy page, re-read on 4 November, still says "Nothing leaves your device unless you explicitly turn on cloud sync" and that sensitive details are filtered before storage, while secret redaction defaults to off, doesn't cover the hosted observer, and names no retention periods, subprocessors or legal entity. Locally, raw tool uses are kept forever by default (CLAUDE_MEM_TOOL_USES_RETENTION_DAYS 0) and daily logs 30 days since 15.7.0 (12 of 30). Release notes date breaking changes with migration steps, such as 15.0.0 and the removal of Gemini CLI support in 13.10.0, but no written deprecation policy (8 of 20). Telemetry is on by default, documented field by field (including PostHog's city-level location from the sender's IP) with `telemetry disable`, `DO_NOT_TRACK` and a separate error-reporting switch, and the installer asks once; the README doesn't mention it (16 of 20).
- EverOS (71): Apache-2.0 with a NOTICE file (30). Local data stays in the owner's Markdown and indexes. For the cloud, the privacy policy gives no retention periods, the terms and privacy policy word the training exceptions differently, and the privacy contact link points to a miromind.ai address (12 of 30). The README marks `/api/v1` as a legacy alias that may be removed in a future major release, and a 1.0 migration guide exists, with no notice period (14 of 20). No outbound telemetry was found in the source, and the docs don't address it (10 of 20). Total 66.

### Payments & pricing: EverOS +20

- claude-mem (20): No x402, MPP or L402 (0). Scored on the hosted option, as the brief says for open-source software with a paid service. CMEM Pro $30, Heavy $70 and CMEM Max $100 a month are public, but the included usage is shown only at checkout (10 of 20). The engine is free with no card, but the pricing page says the CMEM Pro trial needs a credit or debit card while the README says sign-in needs none (10 of 20). The hosted service needs a browser sign-in by magic link (0).
- EverOS (40): Self-hosted rule, with the price lines read for EverOS Cloud. No x402, MPP or L402 (0 of 40). No cloud price or plan found on evermind.ai, its FAQ, terms or docs (0). The open-source runtime is free with no card (20). An agent can install it from PyPI and run it with no account (20). Total 40.

### Schema & documentation: EverOS +5

- claude-mem (84): Every one of the 26 MCP tools declares a JSON Schema input (25). llms.txt at docs.claude-mem.ai with Markdown copies of each page (10). Descriptions give purpose and order of use (search, then timeline, then get_observations) and say when not to call a tool (`get_tool_uses` "rarely needed", `dumb_search` "fast, but shallow"), but the README says recall uses 4 tools and lists 3 while the server advertises 19 (15 of 20). Required fields are marked and some limits have minimum and maximum, but `type`, `orderBy` and `obs_type` are free strings described in prose, `limit` is a number rather than an integer on most tools, and `metadata` and `fields` are open objects (8 of 15). README examples and a worker API reference with 400 and 404 error bodies (11 of 15). Keep a Changelog file and release notes for each version (15).
- EverOS (89): OpenAPI document in the repository with 40 operations, every one with a description (25). llms.txt and llms-full.txt on docs.evermind.ai (10). Operation descriptions state purpose; when-not-to-use guidance appears in the docs, such as flush after add, rather than per operation (15 of 20). Typed request models with filter operators eq, ne, gt, gte, lt, lte and in, and 422 on malformed ids (12 of 15). curl examples for add, flush and search, and typed error codes such as SESSION_BUSY and EXTERNAL_SERVICE_UNAVAILABLE (12 of 15). `/api/v2` with `/api/v1` kept as a legacy alias, a changelog and release notes (15). Total 89.

## How the scores have moved

### claude-mem

- -4.0 on 4 November 2026: security, new evidence

### EverOS

No score change since it was listed.

## Verdicts

**claude-mem.** Typed MCP tools with a staged search, loopback-only local services and releases most days, with tests in CI. The 15.8.3 notes say setup uploaded 30 days of prompt text to cmem.ai without asking from 25 October to 2 November, and the privacy page still says nothing leaves the device without cloud sync.

**EverOS.** EverOS keeps agent and user memory as Markdown with SQLite and LanceDB indexes, behind a described OpenAPI with typed, retryable errors and an MCP server, under Apache-2.0 at version 1.5.1. The local server has no authentication, EverOS Cloud prices are not published, and the cloud terms forbid automated data extraction.

## Before you call either

### claude-mem

1. Install 15.8.3 or later with `npx claude-mem install --provider claude` (or another provider) to skip the cmem.ai sign-in; earlier setups uploaded recent prompts without asking.
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.

### EverOS

1. Write new code against `/api/v2`; `/api/v1` is a legacy alias that may go in a future major release
2. Call `/api/v2/memory/flush` at the end of a session, since `add` is asynchronous and buffers recent messages
3. Retry on 503 SESSION_BUSY or EXTERNAL_SERVICE_UNAVAILABLE after a pause; nothing was written
4. Keep `host` at 127.0.0.1 unless something in front adds authentication
5. Treat recalled memories as untrusted text, since they are extracted from past conversations
