In most ways, the two are essentially the same.  With Full Site Editing-WordPress offered, you can build the site with full site editor but with Porto’s, you can edit your content and build the layout with the Template Builders. Additionally Porto’s Full Site Editing clean the unnecessary theme options and meta options.

They are totally the same(except for the name). Porto introduced the Soft Mode with the release of 6.3.0.  In Porto 6.6.0, Soft Mode is renamed to Full Site Editing.

Full-Site-Editing is the ability to edit all elements of a site including header, page content and footer using Gutenberg blocks. With Full-Site-Editing, you can now edit both an individual post’s content and, with the release of Gutenberg 9.6, the template that an individual post uses.

If you want to build your site with Gutenberg then please make Full Site Editing option enable in theme option to use FSE.

Porto is compatible with FSE and we provide several header elements for users.

In Porto, Gutenberg Shop 4 is built by FSE.

Full Site Editing (Soft Mode) – a New Feature that boosts to a huge development

We have proposed a new feature. Too delicate, complicated settings must have been disturbing your understanding but now this new feature has arrived to liberate you.

If you active this mode, most of options are removed. In this mode, you can use only template builders to full-site edit. Theme options and metaboxes that are unnecessary and overridden are removed. You will be no longer disturbed from complicated relationships of options.

Now it’s possible to edit anything. Say goodbye to word “static”. You can build any type the way you want or simply download it using studio.
