Dub is the only link management tool that allows you to add a custom domain for free. On Dub, you can add as many domains as you want on all plans – including the free plan.
This guide will show you how to add a custom domain to Dub.
Prerequisites
Before you begin, you'll need the following:
- A Dub account. If you don't have one, you can create one for free.
- A domain name. If you don't have one, you can purchase one from any one of the following domain registrars:
Step 1: Add a custom domain
First, log in to your Dub account.
Don't have a project yet?
- Navigate to the Dub Dashboard and click on the Create project button.
- Enter the domain you want to use under the "Shortlink domain" input and click Create project.
Already have a project?
If you already have a project and are looking to add another domain to it:
- Navigate to your project's Domains page – you can do that by clicking on the Domains link in the menu bar at the top of your project dashboard.
- Click on the Add Domain button.
- Enter the domain you want to use and click Add domain.
Step 2: Configure your domain
After adding your domain, you'll be presented with a DNS record that you'll need to add to your domain's DNS settings.
Adding an apex domain
If you're adding an apex domain (e.g. example.com), you'll need to add an A record with the following values:
- Name:
@(or leave it blank) - Value:
76.76.21.21 - TTL:
86400(or the highest value possible)
Adding a subdomain
If you're adding a subdomain (e.g. go.example.com), you'll need to add a CNAME record with the following values:
- Name:
go(or whatever subdomain you want to use) - Value:
cname.dub.co - TTL:
86400(or the highest value possible)
If you're using Cloudflare as your DNS provider, you might need to configure some extra steps for it to work properly. Please refer to our guide on using Cloudflare domains with Dub for more information.
Step 3 (optional): Verify domain ownership
This step is only applicable if you are adding a domain that is currently being used on Vercel.
Since we use Vercel as the DNS provider for Dub, you'll need to verify that you own the domain before you can add it to your Dub project.
To do that, you'll need to add a TXT record with the following values:
- Name:
_vercel - Value:
vc-domain-verify=...(the value will be provided to you on the Dub dashboard)
Warning: If you are using this domain for another site, setting this TXT record will transfer domain ownership away from that site and break it. Please exercise caution when setting this record.
How long do I have to wait for my domain to work?
Domain configuration can take anywhere between 1 to 24 hours to complete. If your domain still doesn't work after 24 hours, please send us an email and we'll be happy to help you out.
