What Is an SSG?
A Static Site Generator (SSG) is a tool that builds websites by converting content into static HTML files.
Instead of generating pages dynamically on a server, an SSG prepares all pages in advance. The result is a set of ready-to-use files that can be hosted anywhere.
How an SSG Works
The process is simple:
- You write content, often in Markdown.
- You define templates for how pages should look.
- The SSG combines content and templates.
- It generates static HTML files.
- You deploy these files to a server or hosting platform.
Once built, the website does not need a database or server-side processing to run.
Why Use an SSG?
SSGs are popular because they:
- Load very fast since pages are pre-built HTML.
- Are more secure due to the lack of a live backend.
- Can be hosted easily and often at low or no cost.
- Produce lightweight websites with good performance.
Common Use Cases
Static site generators are often used for:
- Personal blogs.
- Portfolios.
- Documentation websites.
- Landing pages.
- Projects with mostly static content.
They are best suited for websites where content does not change constantly.
CMS vs SSG
| Feature | CMS | SSG |
|---|---|---|
| Content editing | Easy, visual interface | File-based editing |
| Performance | Depends on backend | Very fast |
| Hosting | Requires server or platform | Simple static hosting |
| Best for | Frequent updates, teams | Performance-focused sites |
Final Thoughts
A static site generator creates websites that are fast, secure, and simple to deploy. It is a strong choice for developers who prefer working with files and want full control over the final output.
SSGs focus on performance and simplicity by generating everything before the site goes live.
