Or pay nothing and run it yourself
Memory OS is MIT licensed — a full permissive grant, with no Commons Clause, no BSL and no open-core carve-out.
Self-hosting is not a stripped edition. It is the same twelve layers, the same retrieval engine, the same governance controls and the same MCP server, without quotas. You bring Postgres 16 with pgvector, a machine to run it on, and the operational attention any stateful service needs.
What the hosted service adds is the part nobody enjoys building: Auth0 tenancy, Stripe billing, backups, the status page, the alert receiver and someone whose job it is to notice.
HOSTED
+ Auth0 tenancy and RBAC
+ Stripe billing and quotas
+ backups, status page, alerting
+ support desk with an SLA
+ metered Pcnaid AI provider
SELF-HOSTED
= all twelve memory layers
= all 141 endpoints
= all 18 MCP tools
= forced row-level security
= audit chain and PII vault
// no quotas, no licence fee

Pricing questions
Including the ones with answers we would rather were different.
Is there a free trial?
No. We would rather not advertise one we have not built — there is no trial period wired into checkout today. The Free plan is the trial: it is not time-limited, and it runs the same twelve layers and the same 141 endpoints as every paid plan.
What happens when I hit a quota?
The request is refused with HTTP 402 and a link to upgrade. There is no metered overage billing — quotas are a hard ceiling rather than a meter that keeps charging. The dashboard warns you as you approach one.
What exactly is metered?
Three counters, per calendar month: memories stored, chat requests, and knowledge base sources. Nothing else is counted. Retrieval, Fabric writes, webhooks and MCP tool calls are not metered.
Does a plan limit which features I get?
No. Every plan has every capability. The plans differ only in volume, tenant count and how quickly a human answers you.
Can I just run it myself?
Yes, and it costs nothing. The source is MIT licensed and self-hosting gives you the same system without quotas. You supply the Postgres, the operations and, if you want model-backed summarisation, the provider keys.
Do I need an OpenAI or Anthropic key?
No. With no provider configured, summarisation falls back to deterministic extractive summaries and retrieval to a local embedding model. Providers make it better; nothing stops working without one.
How do I pay, and how do I stop?
Stripe Checkout for monthly or annual, and the Stripe Customer Portal for card changes and cancellation. Subscription state syncs back through a signature-verified webhook, and duplicate Stripe events are de-duplicated.
Start on the free plan
It is not time-limited and it is not a cut-down build. When you outgrow it, $29 a month is one click away.
