Wren CMS

Wren is a content management system in the spirit of sNews, rebuilt from scratch for modern PHP. Upload one file, open it in a browser, and answer three questions — that's the whole installation. It provides articles and pages, markdown writing, dropdown menus, image uploads, moderated comments, RSS, a live sitemap, Open Graph tags and IndexNow pings, plus optional two-factor authentication. Theming is a single HTML file with nine placeholder tags, so any designer can restyle a site without learning a template language. Upgrades are "replace one file" — the database migrates itself. Deliberately excluded: plugins, page builders, and visitor accounts, so the codebase stays small enough to read in an evening. MIT licensed, free forever.
