Neos is an open-source Content Application Platform and CMS designed for developers and editors to easily create, manage, and optimize intuitive, customizable content experiences.

---

🚀 Overview

Neos is a flexible open-source CMS that revolutionizes content management by combining an intuitive editing experience for non-technical users with powerful customization options for developers. It solves the common problems of traditional CMS platforms, such as rigid structures, poor editing UX, and limited extensibility, by offering true inline WYSIWYG editing, custom content modeling, and seamless integration capabilities.

This project is built for content editors who need a fun and efficient way to type, insert media, and publish without barriers, and for developers seeking full control over content repositories, user experiences, and third-party integrations. It's particularly suited for organizations handling multi-site, multi-language content at scale.

Neos was developed as an evolution of earlier CMS efforts (like TYPO3 Neos) by the Neos community to create a future-proof, event-sourced content framework that's trusted by enterprises like 1&1 and FOUR PAWS, with long-term support (LTS) versions and active community backing.
