What is a Static Site Generator?[Complete Guide]


A static site generator(SSG) is an application that creates complete websites from templates and data content.

The content is usually written in Markdown, HTML or other templating languages and saved in text files. The static site generator takes these text files, combines them with the templates. Then, it generates complete web pages and saves them in a folder.

Finally, you can upload the complete website to any server of your choice.

Why Use Static Site Generators

Static site generators offer the advantages of static websites as well as those of Content Management Systems.

Websites created using static site generators are blazing fast. After all, static site generators creates HTML files that are saved on the server. When a user visits the website, the website server dishes out the HTML file(s).

Content management systems on the other hand have to generate the complete HTML page every time a reader visits the website. The intermediate step of waiting for the server to generate the page adds to the waiting time before the reader can view the website.

Static site generators vs CMS illustration

Managing websites created with static website generators is a breeze.

Instead of creating individual HTML files for your website, you create templates containing the repeated sections of your websites. So if you are managing a website with 20 web pages, you can make changes on one template file and the changes are reflected on all 20 web pages. The alternative would be to make the same change in all 20 files one by one.

Advantages of using Static Site Generators

  • Fast loading speeds Website created using static site generators loads faster since no databases are involved.
  • Unlimited customization The website CSS and Javascript files are easily accessible to the developer. Nothing is hidden. They can change anything they want on the website’s design, layout and components.
  • Smooth scaling with high traffic CMS websites usually struggle when they receive high traffic within a short time. With SSG’s, you can host your websites on a cdn making the websites availability consistent even with traffic spikes.

Disadvantages of Using Static Site Generators

  • Fewer themes, templates and plugins compared to content management systems Compared to CMS’s like Wordpress, Static site generators have a smaller selection of templates and plugins that can be used to extend your website’s functionality. However, you can easily add that functionality if you know the language used to create the themes, templates, and plugins.

  • Require Commandline use to setup Most SSG’s require using command line tool to setup and run the website. Netlify and Vercel also provide a one click install service to setup a working SSG website on their servers. No need to run any commands. You can also install Publii app on your computer and use it to setup and run your static site generator website without touching the terminal.

Hosting for Static Site Generator Websites

You can host websites created through static site generators on any website host. You just upload the website folder on the host’s server and voila, your website is live.

However, this can become tedious if you have to reupload a whole folder every time you make some changes to your website.

Some hosts like Netlify and Vercel takes the pain out of this process. All you have to do is connect your site in Netlify or Vercel with Github.com. Anytime you save your content files in Github.com, your site is automatically built and uploaded to the server.

They do all the processing and uploading of the website in the background. You can focus all your energy on working on the content in the markdown text files.
