These are the numbers the product enforces, read from the program itself, so they are the same on every plan unless a row says otherwise. The plan allowances are at the end.

Rates (to protect your account and your sites)#

What Limit
Sign-in attempts 5 a minute for one email address from one connection
Team invitations and resends 15 an hour and 40 a day for one account
Support requests 20 a day; 5,000 characters; 15 MB of attachments

The actions below share one count per person. Every upload, every preview in the mapping editor, every Check again, Read again, Retry and Publish, and a few other buttons such as refreshing a site, add one to the same count. The count starts again a minute after the first request. Each button is refused once the count has reached that button's own ceiling:

Button Refused once you have made this many requests in the last minute
Publish 10
A new configuration, an upload, Check again, Read again, Retry, Retry safely 20
A preview in the mapping editor 120

So Publish can be refused although you pressed it once: ten requests of any of these kinds in the same minute are enough, and the previews of a busy minute in the mapping editor are many. Crossing a limit shows You've reached a limit that protects your account and your sites. Try again in … Your changes are still on this page. The time in the message is how long to wait. Nothing was sent or changed by the refused click.

Plan allowances#

Free Small Medium Large
Connected sites 1 1 5 20
People in the workspace 1 3 10 30
Record writes a month 100 10,000 25,000 100,000
Image transfer a month 500 MB 20 GB 50 GB 200 GB

Allowances renew once a month, counted from the day your subscription started (or, on the Free plan, the day the workspace was created), not on the first of the calendar month. Plans and allowances explains what counts.
