Domains
Connect your own domain with Pro.
Every site starts on an HTTPS address at mightybuilder.site. Pro lets you connect a domain you own, and MightyBuilder issues and renews its HTTPS certificate automatically.
Included with Pro
HTTPS on its own
A real address first
Getting there
Connecting a domain takes two DNS records.
Build on the free address
Every site gets a name at mightybuilder.site the moment it is created. It is a proper address over HTTPS that you can send to a client, rather than a preview link that expires.
Add your domain
With Pro, type it into the Domain tab and point your DNS at the addresses shown. Both the bare name and the www version, if you want both. It takes effect right away, before you publish.
HTTPS renews automatically
The padlock appears the first time somebody visits the name, and MightyBuilder keeps the certificate renewed from then on.
Included by design
You keep the domain, and HTTPS is included.
HTTPS on every site
Every MightyBuilder address uses HTTPS. Custom domains on Pro get it too, automatically.
Your domain on every Pro step
Your own domain comes with Pro, on the smallest step as on the largest. You never pay more just to use your own name, and the free address you started on keeps working afterwards.
Direct ownership of the name
Buy the domain at a registrar of your choosing and keep it in your own account. You retain direct ownership if you later move the site elsewhere.
The details
How the address behaves after setup.
One real address
Anything that is not your chosen address forwards to it immediately. example.com and www.example.com end up as one site rather than two, which is the difference between one page ranking properly and two pages half-ranking.
A name nobody else can take
The free subdomain is checked as you type, and a name already in use is refused there and then rather than at the end of a form. A handful of names are reserved: ones we run something on, and ones we could not take back off a paying customer later.
Your site is not on our domain
Published sites run separately from the dashboard, on a different domain and security boundary. Code running on a website cannot reach an account.
It stays up when we are busy
A published page is a static file served at the edge, so the thing that keeps your site online is not the thing that runs the dashboard. Deploys, releases and dashboard problems do not reach it.
Questions about domains
Does a custom domain cost extra?
Connecting your own domain is included with every Pro step. You buy the name from a registrar and pay them for it, as you would anywhere. A free site has its own HTTPS address at mightybuilder.site.
Do I have to buy the domain from you?
Buy it wherever you like and point it here. The name stays in your account at the registrar you chose, so you keep direct ownership of it.
What about the padlock in the address bar?
MightyBuilder issues the HTTPS certificate on the first visit and renews it automatically while the domain points here.
Can I have both example.com and www.example.com?
Yes. Both work, one is the real one, and the other permanently forwards to it. That way search engines see one site rather than two copies competing with each other, which is the most common way a small site halves its own ranking.
What do I get before I have a domain?
A real address on mightybuilder.site, over HTTPS, that works properly. It is not a preview link. It is your site, live, on the free plan. It stays working after you attach your own name, too.
How long does a domain change take?
The change on our side is immediate and does not wait for Publish. After that it is DNS propagation, which is between you and your registrar and usually takes minutes.
