+This creates a functioning anonymous instance with no login auth defined. Unclear of how users are managed, maybe all in cookies, does weird stuff like giving user named like @guest and @you (possibly to multiple users simultaneously). Multiple people can edit the same table, data will update to other user, but there's no notification of collaborative editing: no user list, and no cursor to show what other user is doing.

 ## Baserow
 * Doesn't appear to offer read/write anonymous links
 
+## Cryptpad
+* Garbage mobile UX
+* Possibly can be helped by self-hosting, and either commenting out code or doing CSS display:none hacks to improve UX.
