What is Pages Domain (byob.page)?
The hosted-site suffix for BYOB projects. Every publish gets a stable address on it instantly; custom domains layer on top when ready.

Publish Slug
A project’s public identity (`slug.byob.page`) before or alongside a custom domain. Slugs are stable, shareable, and never hardcoded into generated code.
Custom Domain
Your own address (you.com) instead of a builder subdomain, with automatic SSL. The trust baseline for anything commercial: subdomains convert worse and rank no better.
Cloudflare Worker
Serverless code running on Cloudflare’s edge network, close to visitors worldwide. BYOB deploys generated apps as Workers: no servers to provision, scale, or patch.
Dispatcher Worker
The SaaS router that maps each request — by publish slug or custom domain — to the right per-project Worker. One edge entry point, thousands of isolated apps behind it.
Dispatch Namespace
The isolate group containing a fleet of per-project Workers. Namespaces let one platform deploy, version, and route user projects independently.
KV Domain Map
A key-value lookup binding slugs and custom hostnames to their Workers. Custom-domain support is a map entry plus DNS — no redeploy required.
