Launch kit
Got the domain. Now make it work.
Pick what you built the site with (Lovable, Bolt, v0, Replit, Framer and more), who handles your inbox, and what your app sends email through. You get every DNS record to add, with the right names and values, and TLDMath checks public DNS to show what’s already in place.

Common questions
What is a custom domain?
Your own address, like yourname.com, instead of the free one a host or builder gives you, such as yourapp.vercel.app. It’s registered in your name at a registrar, so it stays yours when you change hosts.
How do I get a custom domain?
Register one at a domain registrar, usually for a yearly fee: search a name on TLDMath to compare the first year and the renewal at 8 registrars. Then add the DNS records your host asks for, which this launch kit lists and checks.
What does the launch kit do?
Pick your host or AI app builder, your inbox and your app-email service. It lists the exact DNS records each one asks for, merges every SPF into one record and keeps one DMARC, then checks them against live DNS so you can see what is still missing.
Where do the records come from?
From each provider’s own documentation, linked next to its records. Values that differ per account, such as verification codes, are marked so you copy them from your dashboard instead of guessing.
Can it make the changes for me?
The step-by-step panel gives commands for your own tools: the Vercel CLI, and the Cloudflare and Resend APIs with your own tokens. TLDMath never asks for your keys and never changes DNS itself.
Do you keep my domain?
No. The live check reads public DNS and stores nothing.
