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

1. Publish your Bool — custom domains only work for a live deployment.
2. Add the domain in Bool — open your project → Dashboard → Domains, enter the hostname (for example www.yourdomain.com), and save.
3. Copy the DNS values Bool shows — for most www hosts that is:

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.

4. Update DNS at your registrar using the guide that matches where you bought the domain.
5. 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

After DNS is set

1. Wait a few minutes.
2. In Bool, open Domains and click Refresh.
3. When status is Active, visit https://www.yourdomain.com — you should see your Bool over HTTPS.
