Cognee: review, pricing, security and alternatives

What Cognee does

Cognee belongs to the agent infrastructure family: technical building blocks for agents: memory, execution sandboxes, model gateways, observability, evaluation. On our grid it ranks #5 of the 28 projects of this family listed in the directory.

It is not an agent in itself: it is a component other agents use (memory, isolated execution, web access, model gateway or monitoring). You pick it based on the agent or framework it has to equip.

You use it from: developer SDK and API. Usable models: any OpenAI-compatible model. It can run on your own machine or server.

Who is Cognee for?

It is for teams running agents in production that need a reliable component: isolated execution, memory, model gateway or observability. Typical tasks people give it:

• isolate code generated by an agent
• track model call costs and errors
• give an agent long-term memory

It is a good candidate if your data must stay on your machines.

Access and human control

Its documentation does not detail the access granted to the agent: check the settings before connecting it to your accounts.

We could not establish whether it asks for human approval before sensitive actions: test it first on an unimportant account or folder.

Cognee pricing

The code is free, under the Apache-2.0 licence.

Getting started with Cognee

1. Install it: the project ships as a Python package (install with pip or uv). The exact command is in the repository README.
2. Start with the minimal example from the docs, then add one tool at a time and check what the agent does with it.
3. Give it a short, checkable task, review the result and its action log, then raise the difficulty step by step.

Security: risk level

An infrastructure component sees prompts, keys and data pass through: self-host it or read the service's retention policy.

Three habits: least privilege (minimal rights, dedicated keys), human approval for irreversible actions, a sandbox for code execution. The AI agent security check reviews your setup in a few minutes.

Cognee vs other agent infrastructure

GitHub stars of the best-rated open-source projects in the agent infrastructure family. Stars measure attention, not quality: a heavily promoted project collects them fast, a specialised tool will have few.

Cognee and other agent infrastructure at a glance

The 7 best-ranked agents in the same family, 7 of them open source. The score out of 100 only applies to open-source projects; for proprietary services we show the published entry price. A dash marks information the documentation does not state.

How we rated it

Score: 85/100, computed only from public, verifiable data, with no subjective testing or partnership:

• Adoption 30/40: 32,717 stars on a log scale (40 points from about 200,000).
• Activity 30/30: last commit less than a month ago, 23 releases in six months, 8,394 commits in a year.
• Framework 25/30: licence, default human approval, self-hosting, model choice and documentation site.

The score does not say whether the agent will succeed at your tasks: it measures how solid the project is. The full grid is on the method page.
