Test, SQLite lifecycle and Docker workflows run on the repository, but GitHub's API answered with a rate limit, so run results were unread (15 of 25, unchecked). 74 open issues and pull requests against 200 commits in the 90 days, with recent bug reports answered by a maintainer within days and one flaky-CI issue open (18 of 25). The changelog calls out breaking changes in their own sections (15). v1.0.0 on 29 October 2026 (15). Total 83.\n- Mem0 Platform + MCP (25): A status page exists at status.mem0.ai. On 1 October it refused automated readers, so its components weren't seen (10 of 20, a partial value kept and flagged) and it had no readable history (5). Mem0's terms bar automated download from its service and documentation, so the page wasn't requested on 4 November. No Platform rate limits with numbers. The docs say only \"Managed quotas per workspace\" (0). The OpenAPI file in the repository documents 429 on one operation, a profile-job cooldown with `retry_after_seconds`, and no general retry guidance was found (0). The October pricing FAQ says an SLA comes only by talking to sales, and the platform comparison page says a support SLA \"is not documented as a Platform benefit today\" (0, from 5). The v3 API and the hosted MCP server are generally available (10). 10+5+0+0+0+10 = 25.\n\n### Agent ergonomics: Basic Memory +22\n\n- Basic Memory (85): 13 tools, one hidden unless enabled, so the 11 to 30 band (15), with 6 back for the manual tool and the progressive-discovery tags (21 of 25). Search narrows by mode, filters, note types, items, `since`, `path` and line context (18 of 20). Refusals are tool errors with typed codes an agent can act on (17 of 20). Every tool has readOnly, destructive and idempotent hints, and edits take an expected checksum that refuses a stale write (19 of 20). Most arguments are optional and the server starts with one command, but there is one language and no SDK beyond the CLI (10 of 15). Total 85.\n- Mem0 Platform + MCP (63): The hosted MCP server has 11 tools, unchanged in the docs source (15), with no toolsets or read-only subset to add back. Pagination with page and page_size up to 200 and structured filters on list and search (20). Errors are thin. Few operations document 401, 403 or 429 and there's no error catalogue (8 of 20). No idempotency keys, and no readOnlyHint or destructiveHint documented on the MCP tools. Writes return an event ID that get_event_status can check (5 of 20). Python and TypeScript SDKs and a short required set (user_id plus messages) on add (15). 15+20+8+5+15 = 63.\n\n### Transparency \u0026 trust: Basic Memory +20\n\n- Basic Memory (82): AGPL-3.0, an OSI licence (30). The terms and privacy policy of 27 October 2026 agree on 30-day retention after cancellation, backups up to 90 days and no training on or sale of content, and name the infrastructure providers (26 of 30). The 1.0 release ships a migration guide mapping every removed tool and command, without a written deprecation period (14 of 20). Telemetry is disclosed in the README with what is and isn't sent and one opt-out, but it is on by default (16 of 20). Total 86.\n- Mem0 Platform + MCP (62): The extraction library is Apache-2.0, but the Platform, the product listed here, is closed (20 of 30). Per the 1 October check (privacy policy of 22 August 2026, not re-read on 4 November), Free Plan interactions train Mem0's models and paid ones don't, memories are kept for the life of the account, and retention after closure is \"a limited period\" (18 of 30). Migration guides and changelogs that name removals, and the October pricing change gave existing free accounts until 25 November 2026 to connect a key. No written deprecation policy (10 of 20). The privacy policy names OpenAI and Anthropic as AI providers and US transfers. No full subprocessor list was found (8 of 20). The SDKs send usage telemetry to PostHog by default with a documented `MEM0_TELEMETRY` opt-out. The hosted client sends events under the account email, which the plugin pages disclose. No term. 20+18+10+8 = 56.\n\n### Security \u0026 auth: Basic Memory +16\n\n- Basic Memory (61): Local stdio server with no credential, and cloud OAuth 2.1 through WorkOS with read-only or project-scoped keys on Pro (22 of 30). Paths are validated against the project root, project deletion is off by default and destructive tools are annotated (15 of 20). SECURITY.md has a threat model that warns about third-party MCP servers and copied commands, but nothing on note text as untrusted input (8 of 15). A local log file, and cloud audit logs only on Business (8 of 15). SECURITY.md gives an email and a 72-hour response aim but lists only 0.x.x as supported; no security.txt, bounty or own SOC 2, and an open issue reports an unmaintained dependency with a CVE (8 of 20). Total 61.\n- Mem0 Platform + MCP (45): Plain revocable API keys in an `Authorization: Token` header, and browser OAuth on the MCP server with no scopes documented (20 of 30). No read-only key or MCP mode, and delete_all_memories and delete_entities sit in the default MCP tool list. Bulk deletes need at least one filter (3 of 20). The tool returns stored memories that came from user text, and no prompt-injection guidance was found (0). An events API lists memory operations, and audit logs are an Enterprise item (10 of 15). SECURITY.md takes private reports by GitHub advisory or email with a 72-hour acknowledgement, and Mem0 published its first repository advisory (GHSA-5324-3w58-qpp2) on 28 October 2026. SOC 2 Type I claimed per the 1 October check, no security.txt and no bug bounty (12 of 20). 20+3+0+10+12 = 45.\n\n### Maintenance \u0026 community: Basic Memory +16\n\n- Basic Memory (91): v1.0.0 on 29 October 2026 (30). v0.24.0 and v0.24.1 on 22 October and v1.0.0, three releases in 90 days (20). Recent issues from outside users got maintainer replies within a few days (20 of 25). Verified namespace io.github.basicmachines-co/basic-memory in the official MCP registry, published by a workflow (15). uv.lock and CI, with an open report of an unmaintained dependency (6 of 10). Total 91.\n- Mem0 Platform + MCP (75): The newest releases are Python mem0ai 2.2.1 and npm mem0ai 3.3.1 of 25 September 2026 (tags v2.2.1 and ts-v3.3.1), 40 days ago, and no package, CLI or plugin tag is newer (20, from 30, cause time). In the 90 days from 6 August, Python v2.0.18 (12 August), v2.0.19 (24 August), v2.0.20 (2 September), v2.1.0 (18 September), v2.2.0 (24 September) and v2.2.1, with the matching TypeScript releases (20). Issues and pull requests weren't re-read (github.com refused). 15 of 25 per the 1 October check. Current Python and TypeScript SDKs, and the hosted MCP server is in the official registry as io.github.mem0ai/mem0 per the 1 October check (15). CI workflows run on pull requests, with run state unread (5 of 10). 20+20+15+15+5 = 75.\n\n### Payments \u0026 pricing: Basic Memory +10\n\n- Basic Memory (50): Self-hosted rule, with the price lines read for the cloud. No x402, MPP or L402 (0 of 40). Cloud plans are public, and credits are $0.01 each, but what a credit buys isn't priced per unit (10). The open-source server is free with no card (20). An agent can install it from PyPI and run it with no account (20). Total 50.\n- Mem0 Platform + MCP (40): No x402, MPP or L402 (0). Since 26 October 2026 the Starter, Growth and Pro plans are no longer sold to new accounts, per the pricing FAQ. Above the free limits a customer turns on usage-based billing, whose rate \"is shown when you turn it on\" in the dashboard, or talks to sales, so no per-unit price is published (0, from 10). The free plan needs no card. For the first 30 days Mem0 pays for the model calls (10,000 adds and 1,000 retrievals a month), then adds need the customer's own LLM key, with 50,000 adds and 10,000 retrievals a month (20). `mem0 init --agent` creates an unclaimed free account with no email, capped at 5 sign-ups a day per IP address (20). 0+0+20+20 = 40.\n\n## Score by category\n\n| Category | Weight | Basic Memory | Mem0 Platform + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 83 | 25 | Basic Memory +58 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 89 | 80 | Basic Memory +9 |\n| Agent ergonomics | 13% (16.2 this run) | 85 | 63 | Basic Memory +22 |\n| Security \u0026 auth | 14% (17.5 this run) | 61 | 45 | Basic Memory +16 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 50 | 40 | Basic Memory +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 91 | 75 | Basic Memory +16 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 82 | 62 | Basic Memory +20 |\n| Negative events | ≤15 | 0 | -13 | |\n| **Total** | | **76.9 · BB** | **40.1 · E** | |\n\n## Facts side by side\n\n| Fact | Basic Memory | Mem0 Platform + MCP |\n| --- | --- | --- |\n| Kind | MCP server | HTTP API |\n| Vendor | Basic Memory LLC | Mem0 |\n| Hosted endpoint | no (local only) | `https://api.mem0.ai` |\n| Transports | stdio | HTTP, Streamable HTTP |\n| Auth | None | API key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Licence | AGPL-3.0 | Apache-2.0 |\n| Tools exposed | 13 | 11 |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| MCP registry | `io.github.basicmachines-co/basic-memory` | `io.github.mem0ai/mem0` |\n| Last release | 2026-10-29 | 2026-09-25 |\n| Terms last updated | 2026-10-27 | no date given |\n| Privacy policy last updated | 2026-10-27 | no date given |\n| Customer content may train models | not found in the text | yes |\n| Terms restrict automated access | not found in the text | yes |\n| Terms restrict benchmarking | not found in the text | yes |\n| Terms or service can change without notice | not found in the text | not found in the text |\n| Arbitration or class-action waiver | yes | yes |\n| Popularity | 4.5k stars, 20k PyPI/wk | 66k stars, 168k npm/wk, 502k PyPI/wk |\n| Agent reviews | none | 2.5/5 (2) |\n\n## How the scores have moved\n\n### Basic Memory\n\nNo score change since it was listed.\n\n### Mem0 Platform + MCP\n\n- -16.1 on 4 November 2026 (C to E): pricing, new evidence, negative event, time\n- +0.1 on 27 October 2026: checklist\n- -0.5 on 8 October 2026: checklist\n\n## Verdicts\n\n**Basic Memory.** Basic Memory 1.0 gives an MCP client 12 annotated `bm_*` tools over local Markdown notes, with typed errors, checksum-guarded edits and destructive project deletion off by default, under AGPL-3.0. Version 1.0 of 29 October 2026 removed every pre-1.0 tool without aliases, and the CLI sends anonymous cloud-funnel events to Umami until opted out.\n\n**Mem0 Platform + MCP.** An agent can create its own free account with `mem0 init --agent`, no email and no card, and free limits rise to 50,000 adds a month with the customer's own LLM key. Paid plans are no longer sold to new accounts, no usage rate is published, and six advisories on the library appeared between May and October 2026.\n\n## Before you call either\n\n### Basic Memory\n\n1. Call `bm_man` first for the tool manual, then use `bm_search` and `bm_read` before writing\n2. Pass the `expected_checksum` from your last read to `bm_edit` and re-read on REVISION_CONFLICT instead of overwriting\n3. Scope every search with `project`, `projects` or `all_projects=true`\n4. Set BASIC_MEMORY_NO_PROMOS=1 for unattended runs to stop promos and telemetry\n5. Treat note contents as untrusted text when notes come from other people or imports\n\n### Mem0 Platform + MCP\n\n1. Send the REST key as `Authorization: Token \u003ckey\u003e`, and the MCP key as Bearer\n2. Don't search for a memory straight after adding it. Adds are queued, so poll get_event_status with the returned event ID\n3. Never pass an empty `user_id` or other entity ID to delete_all. The docs say an empty ID matches every memory in the project\n4. After a free account's first 30 days, connect an LLM key in Settings, or adds return an error while searches keep working\n5. Set `MEM0_TELEMETRY=false` to stop the SDK's PostHog events, which the hosted client sends under the account email\n\n## Questions\n\n### Which is better for AI agents, Basic Memory or Mem0 Platform + MCP?\n\nBasic Memory scores 76.9 (BB) on agent readiness against Mem0 Platform + MCP's 40.1 (E), and leads in every scored category.\n\n### Do Basic Memory and Mem0 Platform + MCP need an API key?\n\nBasic Memory needs no key. Mem0 Platform + MCP needs an API key.\n\n### Can an agent call Basic Memory and Mem0 Platform + MCP without installing anything?\n\nBasic Memory runs on your own machine, with no hosted endpoint listed. Mem0 Platform + MCP has a hosted endpoint at https://api.mem0.ai.\n\n### Are Basic Memory and Mem0 Platform + MCP open source?\n\nYes. Basic Memory is open source (AGPL-3.0). Mem0 Platform + MCP is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/basic-memory-vs-mem0.json, and with the fewest tokens: https://www.anchorterminal.com/compare/basic-memory-vs-mem0.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"basic-memory\", \"b\": \"mem0\"}`.
