Hi Vercel team,
I’m one of the maintainers of is-an.ai, a free subdomain service for AI developers. I’m reaching out regarding a domain verification issue that’s affecting our users when they try to deploy to Vercel.
Current Issue:
When our users try to add a custom domain like my-project.is-an.ai to their Vercel project, the verification process requires adding a TXT record at _vercel.is-an.ai. However, since is-an.ai is a shared domain service where individual users only control their specific subdomain (e.g., my-project.is-an.ai), they cannot add records to the parent domain is-an.ai.
Expected Behavior:
For shared suffix domains, Vercel should request verification at the subdomain level. Instead of requiring _vercel.is-an.ai, it should ask for _vercel.my-project.is-an.ai, which the subdomain owner can actually control.
Impact:
This issue prevents hundreds of AI developers using is-an.ai subdomains from deploying to Vercel, limiting their hosting options and affecting the broader developer ecosystem. (We have 1600+ registered subdomains and keep getting feedbacks regarding Vercel support) We’ve had to advise our users to use alternative platforms.
Thank you for considering this improvement!
