The complicated futility of WordPress
Are there any good options for an open source headless CMS  that works with a static site generator that has a page builder that has quick and accurate live previews before you deploy? E.g. so you can build new landing pages from header, testimonial and contact form blocks.There's lots of options if you just want Markdown but this isn't enough for heavily branded business websites where you need to check how complex pages will look before they go live, like if the h1 text in the header line wraps weird or is hard to read against the header background image.Edit: I get that CMS projects need to make money by the way but the lack of vendor lock-in is a big upside to WordPress.Netlify CMS might be an option (https://www.manuelkruisz.com/blog/posts/custom-previews-next...)?
