What WonderCMS is
WonderCMS is a free, open-source flat-file content management system for simple websites, landing pages, and blogs. It runs self-hosted on Linux or the web and stores content in text files instead of requiring a relational database. Installation consists of unzipping and uploading five files, with no initial configuration. In-place editing, search, blog mode, unlimited subpages, clean URLs, a media library, and page-level SEO fields are included. A theme and plugin installer supports up to 50 themes and 20 plugins. WonderCMS lists HTTPS, password hashing, CSRF tokens, and Subresource Integrity tags for its CSS and JavaScript libraries. The maker describes it as track-free and cookie-less, without ads, tracking, or powered-by links. Requirements include PHP 7.4 or newer, cURL, mbstring, Zip, and Apache mod_rewrite; NGINX and IIS need server configuration. The software uses the MIT License and has a community support forum.
