Fair use & limits
AI credits, concurrent previews, and other limits — what they are and what happens at the boundary.
Two caps show up in daily work: AI credits for generation, and concurrent previews for how many isolated apps can run at once. Both follow your plan — numbers live on pricing, not here.
AI credits
Chat, Evolution Threads, Analyse & Fix, SEO Studio, Asset Studio, ads drafts, and the in-app AI gateway draw from the workspace allowance. Watch the balance under Settings → Billing & Usage. You can add credit packs from that same screen when the period is not over yet.
When the allowance is gone, new AI work cannot start until you add credits or the period renews. A published app that is not calling the AI gateway keeps serving Garage Usta's customers — publishing and custom domains do not pause because a thread cannot run.
Concurrent previews
Each plan allows a number of previews at the same time (or unlimited on some tiers). The current cap is on Settings → Billing & Usage and on Settings → Active Previews.
Hit the cap? Stop a preview you are done with in the Preview Hub, then start the new one. Idle previews stop on their own after 15 minutes, which frees a slot without you deleting code — the repository is untouched.
