PRIVATE

Agent Harbor does not collect any data from model usage and you bring your own subscription, so data never enters Agent Harbor's servers

SECURE

Customize the sandbox at file system and network level to granularly control what agents have access to. Fully auditable workflow.

FLEXIBLE

Agent Harbor integrates with a wide variety of terminals and IDEs, supports remote task management through web and mobile interfaces and allows teams to set up on-prem execution clusters.

OPEN SOURCE

Fully open sourced and extensible. See our guidelines if you would like to learn how to contribute.
