Hey HN, I'm a freelance web developer and got tired of the endless email chains during website QA. Clients would send screenshots with red circles, or worse, Word docs with "the button on the page with the thing." I'd spend more time decoding feedback than actually fixing stuff. So I built Commentblocks. You add a script to your staging site, send clients a link, and they click anywhere on the page to leave a comment. That's it. No signup for them, no explaining how to use it. Each comment captures the exact element, viewport size, browser, and URL. Comments show up in a dashboard or can go straight to Slack/Notion. Built with vanilla JS for the widget (13kb), keeps sites fast. The whole thing is designed to have zero learning curve for non-technical clients. I'd love feedback on the landing page, pricing, or the tool itself. Happy to answer any questions.
