Mobirise

Mobirise is unusual in that it works offline on your computer, giving you full control over your files without relying on a cloud platform being up. The builder includes templates specifically designed for portfolios, and newer versions integrate AI to help you generate content and fill in descriptions for your work samples.

It's a good fit if you prefer working locally and want a completely free option without worrying about monthly subscriptions or being locked into a platform. The offline approach appeals to people who like having their site files stored locally, though it does mean you handle hosting separately.
