Three ways to hand it over
| Method | Where the content lives | Good for |
|---|---|---|
| Share link | Compressed after # in the URL, never sent to a server |
Sending to a colleague to edit, valid forever |
| Share page | In the cloud (the diagram you saved), short link | Password, expiry, view counts, can be revoked |
| File | Word / PowerPoint with the code appended | People who will not open a web page |
Share link: no server involved
“Share link” above the preview (on a phone: in the “Download” panel). Opening it generates the link and copies it to the clipboard; send it on. The recipient sees the same diagram in the same theme and can edit straight away; they edit their own copy, not yours.
The link carries the whole diagram's code and theme. Browsers never send the part after # to a server, so there is no copy on Diagramate's side. That also means the link is the content: do not send anything by link that you would not send as text. Compressed code is usually a few hundred to a few thousand characters; above 8000 the dialog warns you, because some chat apps truncate long links; send a file instead.
The format matches the Mermaid live editor: a #pako: link from there opens here when appended to /editor.
Share page: short link, password, expiry
A share page needs the diagram saved to the cloud first (next section). The lower half of the “Share link” dialog then creates a short link of the form /s/xxxx:
- it opens a branded page showing the latest cloud version of the diagram; save again and the recipient sees the new version on reload;
- optional password; expiry of 1 / 7 / 30 days on a free account (click “Renew 30 days” to keep it going), members can also pick 90 days or never;
- the list shows how often each link was opened; revoke at any time;
- the recipient can download PNG / SVG or “Open in the editor” to get their own copy.
Cloud save: continue on another device
Nothing here needs an account: rendering, export and local auto-save work without signing in, and nothing is uploaded. Signing in only comes up when you click “Save” or the diagram name in the top-left corner (on a phone: “Cloud save” in the “Download” panel), to store diagrams on the server and open them elsewhere.
- Click “Save” (or press ⌘S / Ctrl+S) → sign in the way the site offers (diagramate.com: an email code or Google; diagramate.cn: a phone code or the WeChat QR code).
- Once signed in, give the diagram a name and it is saved. The top bar then shows the name and “Saved”; when the content changes it turns to “Unsaved”, and clicking “Save” again (or ⌘S / Ctrl+S) adds a new version without opening the dialog.
- On another device, sign in with the same account and click the diagram name in the top-left corner: Cloud save lists the same diagrams, and clicking one replaces the editor content. All of them are on the My diagrams page (account menu, or “All my diagrams” in Cloud save), where you rename, delete and see version history.
The free tier holds 3 diagrams (Pro: 1,000); each stores the code, theme, name and the last 20 versions. Exported files are never uploaded.
On the first sign-in, if this device has auto-saved diagrams, you are asked once whether to import them.
Both sides edited
If the cloud already has a newer version when you save (edited on another device, say), the dialog says so: Overwrite stores your content as the newest version (the previous one stays in history); Use the cloud version discards local changes. Pro users can preview and restore any version from the last 30 days under “History”.
