Webflow

Webflow is a design tool that produces real markup, and it makes no attempt to hide that fact. Positioning, spacing and responsive behaviour are edited as the properties they actually are, so a design that could be built by hand can be built here, and one that could not be built by hand cannot be faked.

The content system is what turns that into a website rather than a drawing. Collections define a shape once — a product, a case study, a team member — and pages are generated from them, so a growing site does not become a growing pile of hand-made pages. The code can be exported, which very few tools in this category permit.

The downside is the learning curve, and it is measured in weeks rather than hours. The vocabulary is a designer's vocabulary, the first week is spent understanding why things move when they do, and a reader who wants a site by Friday will not have one. The pricing is also layered — a site plan, sometimes a workspace plan, sometimes an add-on — so the monthly total is rarely the single number on the page.
