Context.dev▲814Hello, My name is Yahia, I've been working on scraping products for a long time and maintain a couple of free sites in my spare time (E.g. knifegeek.io) What prompted this is i've rebuilt scraping infra at every company I've started and finally just made it a product. Pass a URL, get clean markdown, html, images, sitemap or pass a domain, get logos, colors, socials, industry data. Goal is to offer a better service than VC funded competitors at a fraction of the cost. Stealth is included and automatic at no additional cost (normally an upcharge by alternatives). Would love your honest thoughts.
