Public mode
Static release output
NubFlow publishes each page into rollback-safe release folders. Normal visitors receive cacheable HTML/CSS with no database lookup and no session startup.
Performance-first rendering architecture
Websites that edit like a builder and load like hand-tuned static HTML.
This public page intentionally ships no editor bundle, no admin session, no builder UI, and no unused module code. NubFlow renders visitor pages as prebuilt releases with tiny critical assets.

Admin mode
Overlay loaded separately
Authenticated editors use a different URL and bundle that loads selection tools, command menus, drafts, publishing, and rollback controls.
Why it beats WordPress builders
No builder runtime tax for visitors.
- No PHP session for public visitors
- No theme/plugin dependency graph
- No unused widgets or global builder CSS
- Critical CSS only, async islands when needed
- Prebuilt pages ready for CDN edge cache
Release folders
/releases/2026-06-10-001/ with atomic current pointer and fast rollback.
Dynamic forms
Forms load as small progressive islands posting to NubFlow API, never as a full admin runtime.
Images
Responsive AVIF/WebP renditions with lazy loading beyond the hero and fixed dimensions to prevent CLS.
