We don’t provide full DNS controls with free hosting. Our Cloudflare integration only has an “On” and “Off” button. But we automatically push the right records for your website to Cloudflare.
That said, our Cloudflare integration has issues and breaks subdomains, custom CNAME records, MX records and basically any other DNS records that are not your base website. Those can’t be set anywhere, not through us and not through Cloudflare.
