Integrate your Custom domain and Sub-domain with Firebase hosting for free and get ssl certificate integration out to the box.


Lets take a look how to integrate Custom domain and Sub-domain with Firebase hosting. We will be integrating domain purchased from GoDaddy.

Things needed

Firebase console

  • Go to firebase console, select your project
  • Click on Hosting from left panel and then click “CONNECT DOMAIN” button
  • You will see an “Add domain” popup. Type in your custom domain name e.g. and click “CONTINUE”
  • Next you need to verify the domain ownership, for this you need to add a “TXT” record in your GoDaddy account.

GoDaddy Account

  • Login to your GoDaddy account and go to “DNS manage” section.
  • Add a new “TXT” type record, enter Type as “TXT” host s “@” and TXT Value as “google-site-verification=xxxxxxxx” (you can get this from Verify ownership scree we have seen before).
  • Remove any existing “TXT” records if any.
  • Go back to firebase and click “Verify”, wait for few minutes and let firebase verify your ownership and then you can see your site up and running at

Custom Sub-domain firebase section

  • For Sub-domain there is almost same steps with minor changes in adding records.
  • Open Firebase hosting section for your Sub-domain project, click “CONNECT DOMAIN” and this time we will enter Sub-domain name e.g.
  • And as we already verified the ownership for, firebase won’t ask us again :).
  • Click “CONTINUE”
  • For Sub-domain we need to add “A” type record to our GoDaddy manage DNS section.
