Could you build this?
Yes This is a web-based DNS diagnostic tool that queries standard DNS records (TXT, MX, CNAME) and validates SPF/DMARC/DKIM/BIMI strings against RFC specifications. A solo developer can build the entire UI and DNS parsing backend using standard Node.js or Python DNS libraries with an AI assistant in a few days.
