Serious question, in 2026 you can actually have a successful crawler with just curl? I just had to create one for a customer - for their own site - and nothing would have worked without using Chromium.
Probably not for most sites. Example of a site where it'd likely work: a blog made with a static site generator. Example of one where it wouldn't: darn near anything made with React.
It works for the majority of things a text mining scraper would care to scrape. It's not just static sites but also any CMS like wordpress, as well as many JS apps that have server-side rendering. SPA-only sites aren't that common anymore, especially for things like blogs, news and text-based social media.
