An honest comparison for teams choosing a memory layer they can actually own. Every RememberOS claim below is something we can show — the graph-memory advantage is from a reproducible eval, not a slogan; the sovereignty claims (EU hosting, self-host, BYO) are how the product is built. Where we can't verify a competitor's current behaviour, we say so rather than guess.
| Capability | RememberOS | Supermemory | Mem0 | Plain vector DB |
|---|---|---|---|---|
| Graph memory — new facts supersede contradicted ones (current truth) | benchmarked | see vendor | see vendor | |
| Hybrid search (vector + full-text, RRF-fused) by default | see vendor | see vendor | vector only | |
| EU hosting (Germany / Hetzner) | see vendor | see vendor | you choose | |
| Self-host + bring-your-own storage / DB / LLM | see vendor | OSS + cloud | ||
| GDPR self-service: full export + one-call erasure | see vendor | see vendor | DIY | |
| MCP endpoint + SDKs + LangChain / Vercel AI adapters | see vendor | SDKs | ||
| Multi-agent shared memory — per-agent identities, provenance, per-collection access control | see vendor | see vendor | ||
| Managed connectors — server-side sync (Slack, Notion, Google Drive, Linear, Confluence, Gmail, HubSpot) with OAuth | see vendor | see vendor | ||
| Privacy-first analytics (cookieless, no banner) | see vendor | see vendor | n/a | |
| Free tier | $0, no card | see vendor | OSS free | infra cost |
| Paid tier (comparable limits) | $12/mo | $19/mo | see vendor | infra cost |
"See vendor" means we won't assert a competitor's current behaviour we haven't verified — check their docs. The Supermemory $19/mo figure is the comparable-tier price we reference on our pricing; verify current pricing with each vendor.
