Checked October 16, 2026
- Strength. We imported mem0ai 2.2.1 locally, and the cloud plan includes 10,000 add requests and 1,000 retrieval requests per month.

Memory layer for agents. We imported the Python package locally; no account and no model call.
Mem0 stores memory for agents. We installed mem0ai and imported it, with no API key and no model call. The cloud pricing page loaded; a free SaaS tier was not cleanly parsed, so the confirmed free path from this check is the open-source package.
Best for
- Adding persistent memory to an agent you already run
- Python projects that can install the open-source package
Not ideal for
- A full research chat product
- A confirmed free cloud allotment — re-read the pricing page
What we checked
Smoke-tested means we ran a local install or import in an isolated environment. We did not create an account, pay, or call a model.
Hands-on: pip install + import mem0 (mem0ai==2.2.1). No account, no payment, no model call.
Install/import only; no API key, no LLM invoke, no signup.
