Crul looks nice, though, you cannot imagine how many startups that I've seen failed doing a very similar thing as Crul. Wouldn't rely on it.
The problem is complex: Humans generating messy pages
Thank you for the positive acknowledgment and insightful observation. As one of the creators of Crul, I fully understand the challenges inherent in this intricate business and software domain. Our initial emphasis on the browser abstraction layer, predating APIs such as SOAP, REST, GraphQL, etc., serves as a data driver and stateless cluster for interpreting DOM nodes. While we initially lacked programmatic extensibility for custom browser control, as you rightly pointed out, addressing complex edge cases often requires such a feature. Looking ahead, we are exploring the possibility of opening up the core, starting with "Krull," the browser cluster. We welcome feedback to gauge interest in this development.
