| Important considerations |
You operate the server and backups. Daily visitor IDs do not identify the same person across days. Support is community-based, with no SLA. Optional AI clients receive the query results they request; self-hosting does not keep those results out of the client. | Each cloud product is metered separately. The free MIT self-hosted deployment is officially unsupported, with no customer support or guarantees. Only free-plan features are available there; paid-plan features are Cloud-only. |
