| 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. | Cloud Free includes 2 users, 1 project, and 7-day retention. Paid Serverless includes unlimited users and projects with 30-day retention. Self-hosting requires your own infrastructure; Dedicated costs depend on the instance, region, and running time. |
