What is Static 404 Page Template Generator?
A 404 page shows when a visitor opens a URL that does not exist. Static hosts automatically serve 404.html from the site root when a page is not found. A good 404 page helps visitors find their way back instead of bouncing.
quickAnswer
Generate a complete 404.html page with a helpful error message, navigation links, and an optional search box. Place the file at your site root so static hosts serve it when a page is not found.

limitations
- Custom 404 pages only work on hosting platforms that support them. Some shared hosting environments ignore 404.html and show their own default error page instead.
- The generated page is entirely static and does not log or report 404 occurrences. Add analytics tracking separately if you need to monitor missing pages.
- 404.html must be placed at the root of the published output. Files placed in subdirectories or build output subfolders will not be detected as the custom 404 page.
