Saving and sharing
Sharing a diagram
Share links carry the whole diagram inside the URL, after the # — so the diagram is never uploaded, and there is nothing on a server to expire or leak.
How share links work
Copy share link puts the entire diagram into the link itself — compressed, and placed after the #. Anyone who opens it gets the diagram as their own editable copy, added to their own storage. Their edits do not touch yours, and yours do not touch theirs.
The part of a URL after the # is the one part browsers never send to a server. So the diagram travels inside the link and nowhere else: nothing is uploaded, no record of it exists here, and there is no stored copy to expire, leak or be asked for.
When to send the file instead
A share link is right for a quick look. Send the .diagram.json file when the diagram is large enough to make the link unwieldy, when it needs to live in a repo beside the code it describes, or when it should be reviewable in a pull request.
Frequently asked
- Does a share link expire?
- No. There is nothing stored to expire — the diagram is inside the link, so it works for as long as the link exists.
- Can you see the diagrams I share?
- No. The diagram sits after the # in the URL, which browsers never transmit to a server. It is not uploaded, logged or stored anywhere here.
