Connect a domain managed at Namecheap

This guide covers domains whose DNS is managed at Namecheap (BasicDNS / Namecheap Web Hosting DNS). Before you start, add your custom domain in ComputeSphere and copy your service URL — for example d-silver-cobra-ab12c.computesphere.app.

A subdomain takes a CNAME record and a root domain takes an ALIAS record. Both point at your service URL, so there are no IP addresses to copy.

Connect a subdomain​

Use this for www.example.com, app.example.com, api.example.com, etc.

  1. Sign in to Namecheap and go to Domain List.

  2. Find your domain and click Manage.

  3. Open the Advanced DNS tab.

  4. Under Host Records, click Add New Record and enter:

    FieldValue
    TypeCNAME Record
    Hostthe subdomain only — e.g. www (or app, api)
    Valueyour service URL — d-silver-cobra-ab12c.computesphere.app
    TTLAutomatic

  5. Click the green checkmark to save.

note

Enter only the subdomain in the Host field — www, not www.example.com. Namecheap appends your domain automatically.

Connect a root (apex) domain​

A root domain (example.com) can't take a CNAME. On Namecheap, use an ALIAS record, which does the same job at the root — no www redirect needed.

  1. Under Advanced DNS → Host Records, remove any A, AAAA, CNAME or URL Redirect record whose Host is @ (a new domain usually has a parking record there). An ALIAS record can't share the root with them.

  2. Click Add New Record and enter:

    FieldValue
    TypeALIAS Record
    Host@
    Valueyour service URL — d-hello-web-3f9c2a71.computesphere.app
    TTL5 min

  3. Click the green checkmark to save.

The root domain is now served directly. ComputeSphere issues and renews its SSL certificate automatically.

Serving www too?

When you add a root domain, ComputeSphere adds www.example.com with it. Add a CNAME for www as well (see Connect a subdomain) so both go live.

Prefer A and AAAA records?

You can point the root at ComputeSphere's IP addresses instead: add every A and AAAA address shown in Root / apex domains with Host @. Use either the ALIAS record or the address records, not both.

After you save​

Return to Console → Domains in ComputeSphere. The domain moves from Validating to Active once the record resolves and the SSL certificate is issued — usually within a few minutes, though DNS can take longer to propagate. You don't upload or manage a certificate; ComputeSphere issues and renews it automatically.
