Jekyll is a static site generator. It takes text written in your favorite markup language and uses layouts to create a static website.

Using Jekyll for creating GitHub Pages offers several benefits, including:

Ease of Backup: Since Jekyll generates static sites, backing up your site is straightforward. You simply need to copy the generated files. This eliminates the complexity associated with databases and ensures that if your server goes down, you can rebuild the entire site from your local copy

Flexibility: Jekyll allows for high flexibility in customization. You can easily add custom meta tags and leverage its theme templating system to tailor the appearance of your site according to your needs

Offline Editing: With Jekyll, you can edit your site offline using any text editor. This approach avoids the issues associated with online editors, such as losing drafts or needing constant internet access. It also means you can work on your site without worrying about server availability 5.
Efficiency: Jekyll sites run quickly and cost-effectively because they don’t require server-side processing like PHP. They can be hosted anywhere that supports file hosting, offering greater versatility in where you choose to host your site.

GitHub Pages Support: Hosting your site on GitHub Pages is free and comes with the added benefits of HTTPS and custom domain support. This makes it a compelling option for those looking for a reliable and cost-effective hosting solution.

Security: Jekyll sites are inherently secure since they consist of flat files. This reduces the risk of vulnerabilities often found in server-side applications. Additionally, hosting on GitHub Pages further enhances security by leveraging GitHub’s infrastructure.

Themes and Plugins: Jekyll supports a wide range of themes and plugins, allowing you to customize your site’s appearance and functionality. You can add a Jekyll theme to your GitHub Pages site to change its look and feel, and extend its capabilities through plugins.

Despite these advantages, it’s important to note that Jekyll might not be the best fit for everyone due to its reliance on local development and the need for familiarity with Git and Markdown. However, for those comfortable with these tools, Jekyll offers a powerful and flexible platform for creating static websites and blogs.
