Introduction

Alpha testing — Nexus CMS 0.1.x is under active alpha. Product usage is free until a stable release. APIs and docs may change; please leave feedback from the site widget.

Nexus CMS turns any Next.js UI into an in-context visual CMS editing layer — with the exact same design — and backs it with a pluggable content store (a Filament/Laravel adapter ships for the MVP).

It is built for developers and software houses. You keep writing normal React/Next.js code; a build-time compiler makes it CMS-ready with near-zero configuration and no visible wrapper components, and a runtime overlay editor lets non-developers edit text, swap images, toggle sections, reorder cards, manage SEO and roll back versions — without breaking your styles.

Why it's different

• No wrapper soup. A build-time compiler injects invisible data-cms-* ids; your source stays readable.
• Override model. Your code is the source of defaults; the CMS stores overrides. You get diff-vs-original, revert and versioned rollback for free.
• Self-contained overlay. The editor renders in an isolated top layer and builds its own hit-targets from measured boxes, so even an image behind text is editable (no z-index dead-zones), and it never clashes with your theme.
• Convention + escape hatches. Names are auto-derived from component/function names. Opt out with // @cms-ignore, // @cms-readonly, or rename with // @cms-name(...).
• Configurable per project. Toggle features (e.g. disable image editing but keep code support) via nexus.config.ts.
