    Hi HN! My name is Nick and this is my fun side project. Please lay it on me. HN can think of Tips.io as a cracked out Tailwind Playground that has page management and amazing AI integration. There are a few core ideas: 1) The HTML is the CMS There are no fields or restrictions. Just hover, click, and start tweaking any HTML. Also, certain elements you click will have special easy edit abilities: - auto creates an uploader, stock photo picker (or HTML) - auto creates an uploader, stock video picker (or HTML) - auto creates a big icon picker (or HTML) - auto creates a WYSIWYG Editor (or HTML)…

    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…

    0github.com is a pull request viewer that color-codes every diff line/token by how much human attention it probably needs. Unlike PR-review bots, we try to flag not just by "is it a bug?" but by "is it worth a second look?" (examples: hard-coded secret, weird crypto mode, gnarly logic, ugly code). To try it, replace github.com with 0github.com in any pull-request URL. Under the hood, we split the PR into individual files, and for each file, we ask an LLM to annotate each line with a data structure that we parse into a colored heatmap. Examples:…

    http://instacss.com (in case DNS update hasn't propagated: http://morning-warrior-3377.herokuapp.com/) Last night I was annoyed at how slow (and web 1.0-ish) most CSS reference sites seem to be, so I created this. It's basically a scrape of the CSS reference on w3schools, but with client side searching. Feedback is most welcome! some of the tech involved: node, requirejs, backbone, mongodb the code: http://github.com/rgarcia/instacss

    Hi HN, I’ve been working on a side project called SocialKit, a simple API for scraping structured data from public social media posts (YouTube, Shorts, more coming soon). It's designed for dev, no-code users, and marketers who want to extract things like summaries, transcripts, details, and more from YouTube. I sold two previous side projects (LectureKit and CaptureKit), and this is my latest attempt at building something useful and focused. I would love to get any feedback :) Happy to answer any questions, and thanks for checking it out! Jonathan

    Hi HN, I built Reviewskits because of a recurring frustration I faced while working for a web agency in Switzerland. Our designers created beautiful, pixel-perfect layouts, but when it came to testimonials, we were stuck with rigid, pre-made widgets from tools like Senja or Trustpilot. Hacking them with CSS to match our UI was a nightmare. When we looked at their API pricing to build our own components for 100+ clients, the cost was astronomical ($90 to $300+/mo). Later, as an indie dev building my own SaaS, I simply couldn’t afford those prices. So I built Reviewskits: High…

    Hi HN, StyleKit is a Chrome extension I developed to help teams quickly capture and document website design systems. It's free to download and use. As someone who works on both design and development, I frequently study and record how websites look for different projects, or document the design of other sites for an aspect I really liked. This takes a lot of my time: opening web developer, finding style classes, viewing the computed style to see what was actually happening, and then storing information I wanted to save. Sometimes I couldn't find an element either way. I created StyleKit to…

    Built this to give AI assistants native Reddit access. No more copy-pasting links. You can ask things like "what's the sentiment on TypeScript vs JavaScript in r/webdev" or "analyze the top posts about GPT-5 today" and get instant analysis. Technical: TypeScript, 3-tier rate limiting (anonymous works fine for most), LRU cache under 50MB. Works with any MCP client, not just Claude. Someone used it to track reactions to H-1B changes across different country subreddits in real-time - that was pretty cool to see. Open to feature requests and contributions welcome! Would love to hear how you…
