| 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. | Similarweb estimates external market and competitor traffic rather than replacing first-party site instrumentation; depth, countries, history, and APIs vary by package. |
