What are good alternatives to Webflow that have better web performance?

Webflow isn't very good with web performance. It doesn't purge unused CSS or support code-splitting on deployments. After growing your website with more pages, you often end up with a large single CSS file that has to be loaded on every page.

Now that Google is starting to take into account performances (Core Web Vitals) for ranking pages on Google Search, marketing teams have a higher incentive to improve the performances of their website. Webflow unfortunately isn't very good at satisfying this need.

Is there any other product suited to marketing teams that has better performance capabilities than Webflow? A tool that, like Webflow, doesn't require the help of a developer every time the marketing team wants to change the website.
