I already have several other projects and DNS managed in Cloudflare, so it made sense to keep everything in one place. GitHub Pages would definitely work too.
Where in the process do you integrate your custom domain (ingau.me) ???
I connect the custom domain in the Cloudflare Pages dashboard. Once the site is deployed, you can assign a domain under Pages > Custom Domains, and since I already manage DNS in Cloudflare, it's just a couple of clicks to route it.
