You can sync Safari in the iCloud settings. Also, Chrome, Firefox and probably a lot of other browsers have syncing abilities when you're signed in to their services.
However, syncing in those cases seems to sync ALL bookmarks, history and whatever else. For me, it seems kind of a mess.
These days I just "share" the webpage to Notes (synced with iCloud, the link is saved to Notes and I can open Notes on the other connected devices and subsequently open the website.
