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.

Hi everyone, After four years, I'm finally open sourcing my little markup language that compiles directly to HTML, and has all the "modern" features built into the core, (reactive components, server side rendering, modules, bundling, etc.). No metaframework required! Feels like I really have something here, I'd love your feedback :)
