Zep builds governed context graphs from business data, documents and conversations, for agents that work on customers, accounts and records. Harbor holds the decisions an engineering team made and serves them to its coding agents. Zep has the stronger model of time: every fact is dated. Harbor has the 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 Zep is from its own pages, read on 1 October 2026.
Three things Harbor does for the team behind the agents, each beside what Zep's own pages say about the same job.
Manual, Hybrid or Auto. Whatever you pick, a contradiction waits for a person.
In ZepFacts are extracted automatically. Attribute-based policies decide which user and agent can read what, and an admin can make a memory MCP connection read-only.
Every rule shows how often it was served and how often an answer cited it.
In ZepEach fact traces to its source, and every request and access decision is logged.
Block rules refuse it before it runs, in Claude Code, Cursor and Codex.

| Harbor | Zep | |
|---|---|---|
| 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 context platform for enterprise agents. It ingests business data, documents and conversations into temporal context graphs, built on its open-source Graphiti. |
| Where the knowledge comes from | Slack, GitHub, GitLab, Notion, Confluence, Jira, Linear, Google Drive and Granola, plus what agent sessions record. | Data you send through its API, organised per user, account or domain. Its memory MCP server also captures preferences, corrections, procedures and decisions from chat. |
| 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. | Facts are extracted automatically. Attribute-based policies decide which user and agent can read what, and an admin can make a memory MCP connection read-only. |
| 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 asks for a context block in one call, or an agent reads it through the Zep memory MCP server. |
| 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. | Facts carry dates. When a fact changes, the old one is invalidated rather than deleted. |
| Seeing what was used | Every rule shows how often it was served and how often an answer cited it. | Each fact traces to its source, and every request and access decision is logged. |
| 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. | SDKs for Python, TypeScript and Go, and an MCP server for Claude, ChatGPT and Cursor. |
| Open source and hosting | The CLI, harborloop, is MIT licensed on npm. The service is hosted. | Graphiti is open source under Apache 2.0. Zep itself is hosted, with your own keys or your own cloud 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. | Free with 10,000 credits a month, then $125 or $375 a month, or $1,250 or $3,750 a year. Enterprise is custom. |
| Best for | Engineering teams who want every coding session to start with what the team decided. | Customer-facing agents that work on account, document and business data. |

A team can run its customer-facing agents on Zep and its coding agents on Harbor. The two read different things.
Harbor is in early access, and we let teams in by hand: leave an address and the people who build it will write to you. Zep can be signed up for today.

From Zep's own public pages, read on 1 October 2026, which are listed under the table. Products move, so if a line is out of date, tell us and we will fix it.
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.
