It's not the same exact look of course, but it has dozens of pages, widgets and components that look clean. It's all well formed code too with ES6 JS, Webpack, etc..
> Take a look at the extended license, which you'll be needing in many cases. $999 vs $28, for a single site license. No thank you.
I don't think the license is worded very well. If you read it as "end user" being a visitor of your site then pretty much every theme on themeforest would cost $999 but that's not the case.
I think what the license means is if you're bundling the theme in with a product you plan to sell and distribute then you need an extended license, unless it happens to be for freelance work in which case a regular ($28) license is fine (the "note to freelancers" clause handles that). If you have a free or paid SAAS app or something like then you can use a regular license too because you're not distributing the theme as a paid product.
I've talked to the author of the theme directly and mentioned using it for a course platform I'm building (end users of the site would be paying for individual courses). He didn't mention needing an extended license for that. He even went as far as giving me permission to release the course platform as open source with his theme included[0].
[0]: What I wrote isn't official for saying you can do the same. I recommend contacting the author directly if you have intent to do that.
I haven't tried it with a React app but I have used the theme for one of my projects that's using SCSS, Webpack and ES6 JS. The docs are really good and everything is segmented nicely. It shouldn't be bad to get it set up with React.
I've always liked the Bootstrap 4 CodeBase theme ($28): https://demo.pixelcave.com/codebase/be_pages_dashboard.php
