Show HN: Linkgrabs.com the Simple and Fast API to Fetch JavaScript Web Pages

For some of my work with LLMs and RAG I needed to be able to fetch content from my customer's support site. Basic cURL calls weren't working because the site is an SPA and is rendered completely through javascript.

The trouble it took me to figure out how to capture the rendered HTML from a headless browser and how to do it reliably in production inspired me to create LinkGrabs.com so others would not have to go through the same pain.
