FAQ
Codex Sites FAQ
Short answers for access, prompt structure, storage, public sharing, custom domains, security and alternatives.
Should I build a public website directly in Sites?
Use Sites for internal apps first. If SEO, public traffic and domain control matter, use a repo-backed host.
Do I need D1 or R2?
Use D1 for structured records, R2 for uploaded files and neither for static content.
Can I paste API keys into the checker?
No. Never paste real secrets, auth files, cookies or tokens into any third-party site.
