One of the quieter advantages of a modern build shows up after launch. There's no PHP runtime to patch, no plugins to keep updated, no database to back up and worry about. The attack surface is small by design, and the site mostly just runs.
It still needs hosting, and the first year on Firebase is included with every build: served from Google's global network, fast for visitors anywhere, with deployment and configuration handled by us. What it costs after the first year is on the hosting page, and it's less than managed WordPress hosting, because there's less to manage.
