Mem0 is a memory layer for the agents and apps you build: it remembers what users and agents said and gives it back later. Harbor holds the decisions your team made and serves the ones that apply to the coding agents your engineers run. If your product has to remember its users, that is Mem0. If Claude Code, Cursor and Codex do not know what your team decided, that is Harbor.
Harbor is in early access, and we let teams in by hand. Every line about Mem0 is from its own pages, read on 1 October 2026.
Three things Harbor does for the team behind the agents, each beside what Mem0's own pages say about the same job.
Manual, Hybrid or Auto. Whatever you pick, a contradiction waits for a person.
In Mem0Memories are extracted and stored automatically, and everyone on a repo reads and writes one shared pool. The coding plugin documents no review step.
Every rule shows how often it was served and how often an answer cited it.
In Mem0You can see every memory that was added, edited or served.
Block rules refuse it before it runs, in Claude Code, Cursor and Codex.

| Harbor | Mem0 | |
|---|---|---|
| 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. | A memory layer for AI agents and apps: an API and SDKs that extract memories from conversations and retrieve them, plus plugins for Claude Code, Codex and Cursor. |
| Where the knowledge comes from | Slack, GitHub, GitLab, Notion, Confluence, Jira, Linear, Google Drive and Granola, plus what agent sessions record. | What users and agents say. The coding plugin captures prompts, answers, changed files and test results. |
| 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. | Memories are extracted and stored automatically, and everyone on a repo reads and writes one shared pool. The coding plugin documents no review step. |
| 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. | Your code calls the API. In a coding agent, the plugin adds up to five memories before the first reply, and the agent can search for more. |
| 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. | Newer facts supersede older ones and duplicates merge, on every plan. Pro adds pattern synthesis. |
| Seeing what was used | Every rule shows how often it was served and how often an answer cited it. | You can see every memory that was added, edited or served. |
| 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. | 31 integrations, from LangGraph and CrewAI to Claude Code, Codex, Cursor and OpenCode. |
| Open source and hosting | The CLI, harborloop, is MIT licensed on npm. The service is hosted. | The memory library is open source under Apache 2.0 and self-hostable. The coding plugin runs on the hosted platform, with on-prem on Enterprise. |
| 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. | A free tier, then $19 and $249 a month by request volume. Enterprise is custom. |
| Best for | Engineering teams who want every coding session to start with what the team decided. | Products and agents that have to remember their own users. |

They do different jobs. A team can build its product's memory on Mem0 and still run Harbor for the agents that write the code.

Nothing to migrate and nothing to write. Two weeks in, you see which rules your agents were given and which ones they cited. Leave an address and the people who build it will be in touch.
