Cognee and Harbor both connect Slack and GitHub to coding agents. Cognee is an open-source memory engine you can run yourself and shape with your own ontology. Harbor is a hosted brain with a gate you set, served and cited counts on every rule, and guardrails.
Harbor is in early access, and we let teams in by hand. Every line about Cognee is from its own pages, read on 1 October 2026.
Three things Harbor does for the team behind the agents, each beside what Cognee's own pages say about the same job.
Manual, Hybrid or Auto. Whatever you pick, a contradiction waits for a person.
In CogneeExtraction is automatic, and knowledge that is used and corrected often is promoted. Custom ontologies shape what is stored. No approval queue is documented.
Every rule shows how often it was served and how often an answer cited it.
In CogneeAnswers carry citations, with provenance on Enterprise, and Memory Coverage scores how well memory answered agents' questions.
Block rules refuse it before it runs, in Claude Code, Cursor and Codex.

| Harbor | Cognee | |
|---|---|---|
| What it is | A company brain for a team's coding agents. It learns the rules your team decides and serves the ones that apply to each session. | An open-source memory engine that builds a knowledge graph from your data, plus a hosted Company Brain in Cognee Cloud. |
| Where the knowledge comes from | Slack, GitHub, GitLab, Notion, Confluence, Jira, Linear, Google Drive and Granola, plus what agent sessions record. | Slack, GitHub and Google Drive in Cognee Cloud, with more listed as coming, plus what agent sessions record through its Claude Code and Codex plugins. |
| Who decides what gets in | You set the gate. Manual holds everything for a person, Hybrid adds routine rules and holds the important ones, Auto adds everything else. A contradiction always waits for a person. | Extraction is automatic, and knowledge that is used and corrected often is promoted. Custom ontologies shape what is stored. No approval queue is documented. |
| How it reaches the agent | Hooks add the rules that apply to the session before the agent writes a line. The same rules are on an MCP server, the CLI and /harbor in Slack. | Its Claude Code and Codex plugins add context to every prompt through hooks. Other agents use its MCP server, and there is an SDK. |
| When a decision changes | When a push deletes the file a rule is about, the rule is retired, or flagged if other repos still use it. A newer decision that contradicts a rule waits for a person. | Memory updates as your data does. Bi-temporal memory and conflict resolution are on Enterprise. |
| Seeing what was used | Every rule shows how often it was served and how often an answer cited it. | Answers carry citations, with provenance on Enterprise, and Memory Coverage scores how well memory answered agents' questions. |
| Stopping a risky command | Block rules refuse a command before it runs, in Claude Code, Cursor and Codex, and hand the agent something to run instead. | Not part of the product. |
| Agents | Claude Code, Cursor and Codex. | Claude Code and Codex through plugins, and Cursor, Claude Desktop, VS Code, Gemini CLI and other MCP clients. |
| Open source and hosting | The CLI, harborloop, is MIT licensed on npm. The service is hosted. | Open source under Apache 2.0, runs on one Postgres, and deploys in your cloud or on-prem. |
| Price | In early access: join the waitlist and we let teams in by hand. Free costs nothing for your whole team on one source, Pro is $24 per person a month billed yearly or $30 monthly, and Premium is $36, or $45 monthly. | Free up to 1M tokens, then $1 per 1M tokens and $5 for each extra workspace. Enterprise deploys in your cloud. |
| Best for | Engineering teams who want every coding session to start with what the team decided. | Teams that want open-source memory they can host and shape themselves. |

Both put company knowledge in front of coding agents, so most teams would pick one. The split is running it yourself against having it run for you, with a gate and a count.
