# Opossum CMS

> oCMS is an open-source Go content management system. A single binary, SQLite database and browser-based admin panel support publishing, multilingual content, themes, media and a REST API.

This is the official project and documentation site, https://ocms.tech/. Public documentation and published API content can be read anonymously. Downloads follow the latest stable release; release history and dated guide reviews provide version context. The shared demo is for evaluation, not production storage.

For a page's Markdown representation, use its .md link below or request the original HTML URL with Accept: text/markdown. Guide Markdown uses the current published CMS content. Homepage and Download Markdown are generated from their full rendered theme sections, including all three installation platforms. The crawler and content-use policy is in https://ocms.tech/robots.txt: search=yes, ai-input=yes, ai-train=no.
