Connect a custom domain to your Bool

Point a domain you already own (for example www.yourdomain.com ) at a published Bool. Bool handles HTTPS for you once DNS is correct.

Before you start

* Publish your Bool — custom domains only work for a live deployment.

* Add the domain in Bool — open your project → Dashboard → Domains , enter the hostname (for example www.yourdomain.com ), and save.

* Copy the DNS values Bool shows — for most www hosts that is:

Type Name / Host Value / Target
CNAME www cname.vercel-dns.com

For the bare apex ( yourdomain.com without www ), Bool usually asks for an A record pointing at 76.76.21.21 instead. These registrar guides focus on the common www CNAME path.

* Update DNS at your registrar using the guide that matches where you bought the domain.

* Back in Bool, click Refresh on the domain until status flips to Active . Propagation often takes a few minutes and can take up to 48 hours.

Important rules that apply everywhere

* Delete any existing www A , AAAA , or CNAME records (and parking pages) before adding the new CNAME. Conflicting records are the #1 failure mode.

* Do not put @ in a CNAME host field for www . The host is just www .

* Do not type a trailing period unless your registrar explicitly requires an FQDN.

* Leave TTL on Automatic when available.

Pick your registrar

Registrar Guide
GoDaddy Domain Portfolio → DNS → CNAME for www
Namecheap Advanced DNS → Host Records
Cloudflare DNS Records — must be DNS only (gray cloud)
Porkbun Details → DNS Records
Dynadot DNS Settings → Subdomain Record
Squarespace Domains Delete Squarespace Defaults first
NameSilo Remove PARKED records, then add CNAME
Hostinger hPanel → Domains → DNS
Misk Essentials → DNS
Hover Domain Overview → DNS

After DNS is set

* Wait a few minutes.

* In Bool, open Domains and click Refresh .

* When status is Active , visit https://www.yourdomain.com — you should see your Bool over HTTPS.

If verification still fails, see Troubleshooting .
