How it works

Limits

Sizes, rates and storage, and what happens when you meet one.

Per document

Without an account
5 MB, and it expires in thirty days unless claimed.
Signed in
50 MB.

Per workspace

Free
250 MB in total, counting every version of everything.
Team
5 GB — the tier exists in the code and there is no way onto it yet, because there is nothing to pay for during the beta.
Publishing rate
Unlimited signed in. Ten an hour from one network without an account.

Every version counts towards storage, because every version is kept — that is the promise, and it is also what fills the disk. Your current usage is on the settings page.

Meeting a limit refuses the publish with a sentence saying what to do, rather than failing quietly. If you need more, ask.

What published documents may do

External libraries load
Scripts, stylesheets, fonts and images may come from another host, so a document can reach for a charting library or a web font. Inline styles, inline scripts and inline SVG all work too.
Sandboxed, whatever it loads
The document runs on an opaque origin from a cookie-free domain. It cannot read your account, call the API as you, or reach any other document — and neither can anything it loads, because those run in the same sandbox.
No calls out
fetch and XHR reach only the content origin, so a document cannot post what it holds to somewhere else. A script it loads can still read the page it is in, which is the trade for letting libraries work at all.
