Static vs. dynamic websites: which architecture fits your project?

Static and dynamic websites differ mainly in when and where each page is generated. A static system serves completed HTML files. A dynamic CMS such as WordPress, Joomla or Drupal usually builds a page when it is requested, using server-side code and a database. This architectural choice affects performance, security, privacy, hosting and maintenance.

Publii is a desktop CMS that lets you manage your website locally and publish it as static files. The web server needs neither a Publii database nor PHP nor a publicly accessible Publii admin panel. The comparison below shows where this model offers advantages and when a dynamic CMS may be the better fit.

	Static CMS (Publii)	Dynamic CMS (e.g., WordPress, Joomla or Drupal)
Speed and performance	Publii generates each page as a complete HTML file before publication. The web server can deliver it without a database query or server-side page generation.	Pages are often assembled from database content and templates when someone requests them. Caching and a well-configured server can reduce this additional processing considerably.
SEO and search visibility	Search-friendly URLs, metadata, XML sitemaps, structured data, Open Graph tags and Twitter Cards are built into Publii. You do not need an additional SEO plugin for these features.	SEO features depend on the CMS and its configuration. WordPress and similar systems often add many of them through plugins.
Security and reliability	The published website needs neither a Publii database nor PHP nor a public Publii admin panel. This removes much of the attack surface commonly associated with dynamic CMSs.	A public admin area, server-side runtime, database and extensions increase the attack surface. Regular updates and secure configuration are therefore important.
Privacy and data control (GDPR)	Publii does not add tracking services by default. Whether the published website complies with the GDPR still depends on its configuration, hosting and connected services.	Dynamic CMSs can also be configured for privacy. Plugins, analytics tools, external fonts and other services must be reviewed and, where necessary, controlled through consent.
Maintenance requirements	There is no Publii backend stack on the web server that requires ongoing updates. The Publii app, themes, plugins, integrations and hosting still need maintenance.	The CMS core, runtime, database, themes and plugins require regular updates, backups and monitoring. Managed hosting can handle some of these tasks.
Hosting cost and flexibility	The generated files work on static hosting platforms, object storage and conventional web servers. Because they do not require PHP or a database, the technical hosting requirements are often lower.	Dynamic systems need a compatible runtime and usually a database. Cost and administration depend on the CMS, traffic and hosting model.
Publishing and deployment	Publii supports FTP, FTPS, SFTP, GitHub Pages, GitLab Pages, Netlify, S3-compatible storage, Google Cloud and manual deployment.	Changes are usually published through the web-based admin area. Staging, automated deployment and other workflows depend on the CMS and hosting setup.
Editing and workflow	You edit content in a desktop app, preview the website locally and publish it through a graphical interface. The standard workflow does not require a command line.	A browser-based admin area can be reached from different devices. Ease of use and complexity vary with the CMS, theme and installed extensions.
Scalability	Static files can be delivered efficiently to many visitors through a CDN. Costs, bandwidth and other limits depend on the selected hosting provider.	High traffic may require caching, database optimization, additional server resources and a CDN. Managed platforms can simplify these tasks.
Architecture and data	Publii stores the project locally and generates HTML, CSS and JavaScript files from it. When you publish, the generated files are transferred to the web server or hosting service.	Content is usually stored in a database. Server-side code and templates generate the output, while a page cache may store completed versions temporarily.
Portability and vendor lock-in	The published website consists of portable static files and can usually be moved to another hosting provider with relatively little effort. Changing the CMS may still require a migration.	Portability depends on the CMS and its export tools. Content can often be exported, but themes, plugins and custom functionality may not transfer directly.
Offline work	You can create and edit content offline and check the website in a local preview. Publishing and connected online services require an internet connection.	The web-based admin area usually requires an internet connection. Local work is possible but generally needs an additional development environment.
