Supermemory is fast, benchmark-leading, open-source, and self-hostable — credit where it's due. Teams pick RememberOS instead when they need EU data residency as a managed service with a published DPA, flat predictable pricing instead of usage-based billing, and governed memory across many agents. This is an honest comparison; where we can't verify Supermemory's current behaviour we say so rather than guess.
| Capability | RememberOS | Supermemory |
|---|---|---|
| Open-source & self-hostable | yes | yes (incl. air-gapped) |
| EU-hosted managed option + published DPA | Germany / Hetzner | verify managed-cloud region with vendor |
| Pricing model | flat: free, then $12/mo | usage-based (per unique content ingested) |
| Multi-agent: per-agent identity, provenance, per-collection access control | see vendor | |
| Graph memory — current-truth supersession | benchmarked | see vendor |
| Bring-your-own model / DB / storage | local embeddings/LLM when self-hosted | |
| Free tier | $0, no card | free tier + OSS |
Facts as of June 2026 from public sources (supermemory.ai/pricing, Supermemory on GitHub) — verify with the vendor. Supermemory leads several public memory benchmarks; this page is about residency, pricing model, and multi-agent governance, not raw recall quality.
Is there a Supermemory alternative with predictable pricing? Yes — RememberOS is flat: free, then $12/mo with unlimited collections, versus usage-based billing.
Is there an EU-hosted Supermemory alternative? Yes — RememberOS is EU-hosted (Germany) managed with a published DPA, and also self-hostable.
Is RememberOS self-hostable like Supermemory? Yes — both are open-source and self-hostable; RememberOS runs on Postgres + pgvector with BYO model/DB/storage and adds an EU-managed option.
