Free = full factory capability with manual maintenance; Pro = continuously fed and fully automatic. Rules still ship with every release — Free users get them by reinstalling the latest version.

How seats work

One server = one seat

An agent binds to your account with a pairing code at install time and takes one seat. Reinstalling the same machine (same fingerprint) never takes another.

Mid-term seats are prorated

Add a seat mid-year and pay only the remaining fraction (e.g. US$5 with half a year left). All seats renew together on one date, at full price only from renewal.

Rebinding has a cooldown

Unbinding frees the seat immediately, but each seat can be reassigned at most once per 30 days — normal hardware replacement is unaffected; rotating one seat across many servers is not.
