Neos

Neos is an open‑source content application platform that lets developers and editors create and publish digital content through a visual, inline editing interface. It stores data on the user’s own infrastructure, giving full control over the content repository while supporting multiple languages and sites within a single installation. The system includes built‑in SEO tools, role‑based access control, and a media management center, aiming to meet enterprise requirements for scalability and long‑term support.

The platform is self‑hostable and available under the GPL‑3.0 license, with no subscription fees or tiered pricing. Its architecture is designed for extensibility, allowing custom business domain models to be integrated directly into the CMS. The true inline editor provides a “what you see is what you get” experience, reducing the gap between content creation and final presentation.

Neos targets organizations that need a flexible, multi‑site, multi‑language CMS while retaining full sovereignty over their data. It is positioned as a stable, mature solution suitable for both developers building custom functionality and editors managing complex publishing workflows.
