Free vs Pro
Of 96 operations, 80 are free. Every control that decides whether a write is safe — the preview, the capability check, the snapshot, the verification, the rollback — is in the free plugin and will stay there.
Pro is a second plugin that registers more operations into the same dispatchers. It changes what an agent can reach, not what it is allowed to do without asking.
A plugin that puts a safety control behind a paid tier is selling you the risk and then charging you to remove it. SiteHelm does not have a tier like that and will not add one.
The split is by scope, not by safety. A free operation acts on one thing you named. A Pro operation acts across a site or a shop — every product, every post’s metadata, a settings surface rather than a single value. Both go through the same five gates.
An unlicensed site that calls a Pro operation is refused with
IntegrationUnavailable and told what is missing. It is
never silently ignored and it never half-writes.
A dry run that returns the exact diff before anything is written.
The write is refused unless the WordPress user could have made it by hand.
The prior state is recorded before anything is overwritten.
The write is read back and compared against what the preview promised.
Any recorded change can be put back from the admin.
Every call, its arguments, its outcome and its snapshot.
One switch stops every write on the site, immediately.
Any operation or whole module can be turned off independently.
A connected application can be disconnected without touching the others.
Open an area to see the operations by name. The lists come straight from the plugin’s own catalogue, so they are never out of date with the release you can download.
Site-wide SEO settings, schema, the 404 log and redirections, and bulk fixes across up to fifty posts at once.
Requires: SiteHelm Pro on a licensed site. The 404 log and the redirections list exist only on Rank Math.

Pro adds operations. Anything free in a release you have already installed stays free in every release after it.
Preview, capability checks, snapshots, verification, rollback, the log and every switch are free on every site, licensed or not.
Not at any price. These are excluded from the product, not held back from a tier.
The free plugin is open source, so this is checkable rather than promised: the licence gate is one function call, and you can read every place it is used.
Pro activates on the install you already have. There is nothing to reconnect, no data to migrate, and no second connection for your agent to learn.
You will know you need Pro when you find yourself asking the agent to do the same thing to fifty posts, or reaching for a shop catalogue. Until then the free plugin is the whole product.
Contributors get Pro without paying for it. The contributor programme sets out exactly what qualifies.
