Supermemory: what it remembers, who owns it, and what it costs
thecontinuitylayer.com/memory-systems/supermemoryA memory and context engine offered as a hosted API and as a local single-binary server, with container-tag scoping and automatic forgetting of contradicted facts.
- 1Partly
Is Supermemory open source?
Partly, by Supermemory's own page.
The public repository is MIT and the SDKs, plugins and MCP server are open source, but the self-hosting docs say the server binary is not open source and is free within a lite license limit.
Yes means: The core is under an open-source license.
- 2Yes
Can you run Supermemory yourself?
Yes, by Supermemory's own page.
The full memory API runs locally as a single binary, installed by script, npx or Docker.
Yes means: It runs on your own machine or server.
- 3Partly
Can you take your memory out of Supermemory?
Partly, by Supermemory's own page.
Local data lives in one directory that the docs call easy to back up or move; no export API is documented for the hosted service, and moving from local to the platform does not transfer data.
Yes means: An export, or the data sits in a standard store you own.
- 4Yes
Does Supermemory work with more than one model provider?
Yes, by Supermemory's own page.
Any model: OpenAI, Anthropic, Gemini, Groq or any OpenAI-compatible endpoint such as Ollama, LM Studio or vLLM, with local embeddings by default.
Yes means: It is not tied to one provider's models.
- 5Yes
Is there a hosted Supermemory?
Yes, by Supermemory's own page.
A hosted platform, reached by changing the base URL.
Yes means: A cloud or managed option exists.
- 6Yes
Does Supermemory have a free tier, and what is the entry price?
Yes, by Supermemory's own page.
Free at $0 with monthly credits; Pro at $19 a month; Max at $100; Scale at $399 with a self-hosted option; Enterprise custom.
Yes means: A free tier exists and the entry paid price is published.
- 7Partly
Does Supermemory scope memory per user and per session?
Partly, by Supermemory's own page.
Memory is scoped with projects, called container tags, such as one per user; separate session scoping is not described.
Yes means: Both per-user and per-session or per-agent memory are supported.
- 8Partly
Can you delete a user's memories from Supermemory?
Partly, by Supermemory's own page.
Deleting a container tag removes all its documents and memories, for owners and admins; memories are described as marked forgotten rather than confirmed erased. There is also a forget-one-memory endpoint.
Yes means: A documented way to delete everything for one user.
What these grades say about continuity, and what they do not.
Every grade on this site is read from the maker's own pages. The Continuity Framework asks five things of any system that carries state: that it carry, govern, evolve, prove and forget. These tests reach carry, govern and forget; they do not reach evolve or prove, which no maker's page documents in a gradeable way. A high letter is a good memory system, not a continuity layer.
- M1 Open sourceCarry
- Open source means the memory engine can outlive the vendor; the state is not hostage to a contract.
- M2 Self-hostCarry
- Self-hosting puts the store under the owner's control, which is the precondition for every other obligation.
- M3 ExportCarry
- An export is question C3: can the state leave in a form another system reads? A standard store you own answers it; a proprietary dump only partly.
- M4 Any modelCarry
- Working with more than one model provider is question C2: the memory, not the model, holds the state.
- M7 ScopingGovern
- Scoping per user, agent and session is question G2: who may read and write each item. It is the floor of governance, not the ceiling.
- M8 DeleteForget
- A documented delete for one user is rung 5 of the erasure ladder: the record leaves the store. Derived memories, the index and backups are not covered unless the maker says so. Rung 5 of the erasure ladder: delete the record.
License as stated: MIT for the SDKs and plugins; the server binary is not open source. Every grade above is read from Supermemory's own page on the day shown. If a page has changed, tell us.
