The caps that apply to your apps, in one place: credits, records, letters, domains, uploads, imports, AI and media, the API, workspaces and versions, and the page that explains each one.
Every limit here is also explained on the page of the feature it belongs to. This page gathers them, so you can see what is allowed before you meet one. Open the page in the last column for the whole story.
Where a limit depends on the plan, the table has a column for Free, Pro and Business. The plan that counts is the one of the account that pays for the app. Enterprise has no fixed numbers: they are agreed with you, see Plans and credits.
A figure marked default is the standing limit, and Setherion can change it for the whole platform. If a message in the product quotes a different number, trust the message. A limit that counts "an hour" or "a day" is a pace: it opens again as time passes.
