I built an open-source SEO landing builder (Next.js + Payload). But I need your help — is this actually useful?

The author built an open-source SEO landing page builder using Next.js and Payload CMS to bridge the SEO-Dev gap. This tool allows SEOs to build pages quickly and developers to customize without modifying core code. The project is MIT licensed and self-hosted, providing full control and vendor lock-in freedom. It's currently in development with features like live preview and draft mode planned.
