You might like Builder.io (https://www.builder.io/m/developers) - they let you embed drag-n-drop powered sections within your regular page markup, and it looks like they support most frameworks like svelte.

Is your concern with the fact that clients can lay out their sites with blocks? Note that they can't edit any of the visual aspects unless you create a field for those specifically (e.g. making an image a circle or square).

If it's with not being able to use a local IDE - that is something that's currently possible by bundling your Svelte components into vanilla JS and importing them into your Primo blocks & passing along data as fields - but I'd give it a couple weeks before using it in production until we smooth it out.

But what you've described is essentially how I do my client projects - I build it all with code (usually reusing blocks from other projects) and hand off a site that literally any of my clients can edit on day one with minimal training.

Not so much.

Yes. As a developer I don't want to deal with WYSIWYG drag-n-drop interfaces. I want the freedom to develop using my already established workflows. What you suggest sounds like development for the Primo interface, i.e. Primo dictates the high-level structure and I can develop components for it. What I'd like is at the other end of the spectrum: I develop the entire website in Svelte and make it compatible with Primo by adhering to some constraints.

Sounds like we're on the same page then :)

What you say you’d like is what I’m looking for, too, but what you say Primo is doesn’t sound far enough off that I understand your complaint. When you say “customize blocks” I guess that doesn’t include changing the text? Or perhaps it doesn’t constrict the possible actions enough for you to feel safe handing it over to a client?
