How to Use a Custom Domain with Cal.com for Free

appmasker custom domain with cal.com

Why use a custom domain with Cal.com (formerly Calendso)?

You're likely here for at least one of the following reasons:

  • Branding 💅🏼: You want to own your brand and not link your clients / audience out to a 3rd party domain
  • Broken links 🔗💔: You're not married to Cal.com and might switch down the road, which would render your booking links useless

With AppMasker, you can use your custom domain or subdomain and have it in place of Cal.com's domain, like cal.appmasker.com. Did we mention that you get to use two custom domains for free? Read on to get started!

1. Sign up for AppMasker

Click the button below to create an account, no card required.

2. Create DNS Records

Next, log into your DNS provider where you bought your domain that you'll use. Go to your domain's DNS settings and look for where you can add records. If you have existing records that match the following types, you'll want to replace them. 

NAME
VALUE
A
@
213.188.214.66
AAAA
@
2a09:8280:1::933
TYPE

3. Use the helper link

Make sure you're logged into your AppMasker account in your browser, then click the button below.

4. Configure your domain

After clicking the link above, find the blue "Create A Domain Button" shown below.

Then, enter the domain name you'd like to use in the "Custom Domain Name" field.

Finally, scroll to the "Redirects" section and in the "To" field (circled below), enter "/" with your Cal.com username.
For example, if my Cal.com booking url is "https://cal.com/john-doe/30min", I would enter "/john-doe" as seen below:

Click the bright blue "Create Domain" button at the bottom right when you're done.

Note! It can take up to 24 hours for your new DNS records to propagate, so be patient!

That's it! Try visiting your domain and it should show your Cal.com booking page!

Conclusion

You can create 2 of these domains for free with AppMasker.
