mem0 gives AI agents persistent memory across sessions, and ships in three forms the README sets out side by side: a library you import, a server you self-host, and a managed cloud. The first two run on your infrastructure with your own provider credentials; the cloud is the company's hosted product with its own key, which is a different arrangement and worth not confusing with the other two. Apache-2.0.

Why this trust score (81/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 22/25: The key is supplied by an environment variable or local config file you control.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under Apache-2.0, so anyone can check how the key is handled.
  • Privacy 11/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control. Analytics or error-reporting libraries are present; what they send was not established.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

What was checked

Verification tier RESEARCH_ASSISTED, derived from the evidence below and not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
  • [REPORTED · SOURCE_SCAN] References PostHog, so some analytics or error reporting is present. This scan cannot tell whether it is opt-in or what it sends. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-09-15, about 0 month(s) ago. source

How your API key is handled

Your API key is supplied via an environment variable or local config file. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Install the tool, set your provider API key as an environment variable (or in its config file), and pick a model.
