Welcome to the Q&A Forum

Hi!. You can use MOZ, RSS feed and also IFTTT  to configure the alerts you want. I think you can use them to create backlink alerts. Here is an example at MOZ's Blog: https://moz.com/ugc/get-email-alerts-for-new-backlinks-with-open-site-explorer I can not tell you about Ahrefs, because I do not use it. I hope I could have helped.
