What Exponent CMS is
Exponent CMS is free, open-source software for building dynamic websites. It is self-hosted and lets editors change pages while viewing them, without relying on back-end administration pages. The system supports editorial workflows, custom user roles, multilingual content, reusable or unique content, themes, stylesheets, sub-themes, a media library, SEO tools, and developer solutions. SEO features include page metadata, search-friendly URLs, router maps, canonical URLs, and image alt-text and title metadata. Sample site types include blogs, e-commerce sites, and multipurpose sites. Built-in e-commerce is intended for lightweight store features, requires substantial setup, and handles shipping estimates while shipment processing occurs outside the CMS. Installation uses a web server and database; documentation covers Git over SSH, cPanel, SSH, and FTP. MySQL or MariaDB are recommended, with Microsoft SQL Server also supported. Exponent 3.0.2 is listed as the current stable release and requires PHP 7.4 or later.
