Comments are notes inside source code that are ignored by the compiler or interpreter. They can explain intent, constraints, or tradeoffs when the code alone is not enough. Most languages use line comments for short notes and block comments for larger spans. Too many comments slow down scanning. Redundant notes, outdated explanations, and commented-out code make it harder to see what…from commentclean.com

  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…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
