Reviewing generated screens there is planned. Whether a paid tier comes later is not decided. The intent is that anything that runs inside someone else's product stays free, with no usage metering.

Owners can take someone out of a workspace, and an invite can be withdrawn before it is used.
+
+## Plans
+
+Plans apply to the hosted Studio only. You pay per editor: a viewer is always free, and every other role (owner, design-system, designer, product, engineer) is an editor.
+
+| | Free | Pro | Team | Enterprise |
+|---|---|---|---|---|
+| Price | $0 | $8 a month, or $80 a year | $12 per editor a month, or $120 a year | talk to us |
+| Workspaces you own | 1 | 3 | unlimited | unlimited |
+| Editors | 2 | 1 | unlimited | unlimited |
+| Design systems | 1 | unlimited | unlimited | unlimited |
+| Directions | 1 | unlimited | unlimited | unlimited |
+| Published screens | 10 | unlimited | unlimited | unlimited |
+| Fetches by key a month (screens, Directions, tokens) | 10,000 | 250,000 | 1,000,000 | 10 million or more |
+| Version history | last 10 | all | all | all |
+
+- **Reaching a limit** stops only the new thing: another design system, another published screen, another editor. Studio says which plan has room. Everything you already have keeps working.
+- **Going over your fetches never breaks your product.** Studio warns you at 80% and 100% on the Billing page. If a workspace stays over for 7 days, editing pauses until it upgrades or the month turns; products still get their screens, Directions and tokens.
+- **Billing** is under Workspace → Billing: your plan, your seats, what you've used this month, and the buttons to upgrade or manage your subscription (owners only; payment is through Stripe). On Team, adding or removing an editor changes your seats, prorated.
+- **The founding offer**: the first 100 paying workspaces pay half, for as long as they stay subscribed.
+- **You can always leave**: every design system, screen and Direction exports as JSON on every plan.
