Products that do what Partial content web crawling using HTTP/2 and Go does
Hi, I wrote a low-level HTTP/2 web crawler in Go, which can scrape partial content to save traffic. Tl;dr e.g. the HTML of a YouTube video contains the video description, views, likes etc. in its first 600KB, the remaining 900KB are of no use for me, but I have to pay my proxies by the gigabyte. My crawler receives packet per packet, and if I got everything I needed I reset the request, and only pay-for-what-i-crawled. This is also potentially useful for large-scale crawling operations, where duplicates matter. You could compute a simHash on the fly, and reset on-the-fly before crawling…

Hello HN! I've been working on http://underthesite.com for the last month and now think it is ready for some full strength HN feedback. What do you guys think? It crawls up to 10 pages of a given site while you wait, looking for community-provided CSS / XPath selectors and regular expressions. Additionally, I'd like to appeal to you to submit matchers for technologies that you care about. Technologies are easy to add, so add your favorite jQuery plugins, analytics tools, client-side node.js wrappers, what have you. I'm going to be running a large crawl in the next few days and want to make…
