Both great recommendations! I’ve been building static sites for non-tech clients for the last 5 years, so I’ve also hunted for open-source website builder tools that support multi-page sites and exportable HTML. Another excellent option is Publii. It’s open-source and super friendly for users who don’t want to touch code,but it’s also flexible enough if you do. You can create multi-page static sites, customize themes, and export the full HTML structure to host anywhere you like.
One thing I love is that it works offline, making it perfect for drafting on the go. Plus, when you’re ready to tweak layouts or drop in custom code, it won’t fight you like some other platforms. Great for both beginners and devs who want control.
