Products that do what I built a tool that watches webpages and exposes changes as RSS does
I built Site Spy after missing a visa appointment slot because a government page changed and I didn’t notice for two weeks. It watches webpages for changes and shows the result like a diff. The part I think HN might find interesting is that it can monitor a specific element on a page, not just the whole page, and it can expose changes as RSS feeds. So instead of tracking an entire noisy page, you can watch just a price, a stock status, a headline, or a specific content block. When it changes, you can inspect the diff, browse the snapshot history, or follow the updates in an RSS reader. It’s…

I built this several months ago as I was interested to see how the titles of posts evolve/change on HN. It turns out lots of titles are edited every day (in both subjectively and objectively good and bad ways!) and I've found it interesting to see how titles have evolved. The whole thing is automated and is built around a Ruby script that pulls down the titles on the front page at a frequent interval. Any titles for specific story IDs that change get tracked and rendered out to a static HTML page hosted on Netlify. It runs by itself without incident so far. This has been on Show HN…

Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)

Hi, co-founder of markets.sh here. We are doing a lot of news processing and analysis around stocks and companies. One feature people like to use is “alerts” at certain price points. We have now extended this with LLM filters on the whole news feed so that you can create (near) real-time webhooks on arbitrary events like: - Notify me when Nvidia is worth 10 trillion - Notify me about AI breakthroughs - Notify me when Intel is the market leader again - Notify me about successful Starship launches - Notify me when a war breaks out - Notify me about bankrupt unicorn startups - Notify me about…

Hi HN. I was surprised that there wasn't a feature here that lets you go back in time to the front page of Hacker News on a random day...so I made one. http://randomhackernews.com is a simple HTML page that navigates you to the front page of HN on a random day between today and February 19, 2007 (the oldest date I could find with content). I made this for myself, but figured others may find some interest in it.

Hey HN. I created this website. https://pj4533.com/hn-overlooked/ It's just a simple web app that discovers overlooked posts on Hacker News. I created it because I was often coming to Hacker News and realizing that I was missing a lot of stuff, and there just didn't seem to be an easy way to surface content that was interesting to me but just didn't bubble up to the top of the page. So I built this. I got the idea a while back, one night when I was recording (you can watch it here, it's pretty funny: https://youtu.be/FDyDb4sX30w?si=E3rby-DaGWA6gy0R ). But I…

Hey HN! I'm excited to share a tool I've been working on - a native Hacker News reader built with Rust and egui. Here's a screenshot: https://github.com/haojiang99/hacker_news_reader/blob/main/s.... As a daily HN reader, I've always struggled with keeping track of interesting posts I want to read later. Browser tabs pile up, bookmarks get forgotten, and I lose track of what I've already read. I needed a way to: 1. Browse HN efficiently (across all sections - hot, new, show, ask, jobs, best) 2. Quickly mark posts as "todo" for later reading 3. Mark posts as…

I made a little website with a server that collects only HN submissions with > 500 upvotes chronologically. https://hn.moritz.pm/ It's quite simple because I wanted to learn from the project. But I think it's useful, to get a summary of what was important over the last days. The UI is almost identical to the HN frontpage, you can click on the comments to view the thread and on the username to see the profile. The rest of the cards takes you to the submitted URL.

I developed a small tool to find RSS feeds for websites. You can try it out here: https://lighthouseapp.io/tools/feed-finder In >90% of cases the standard way of checking meta tags is enough to find the feeds. But my goal for this tool is that it finds feeds regardless if they're linked somewhere or not. That if this feed finder doesn't find a feed, no feed exists. It's a big goal and admittedly not there yet, but it does a few things that are a step in that direction. * Checks meta tags of parent pages (sometimes the article itself doesn't have the meta tag, but the main…

I was overwhelmed by the pace of AI news and papers coming out, so I built an automated HN news monitoring service that delivers relvant news straight to my inbox or RSS feed. It uses LLMs to extract, summarize, and classify the front page articles and analyzes the different perspectives in the comments. No more FOMO :)

Hi everyone, I built a tool a few years ago called RSS Lookup(https://www.rsslookup.com/) and recently made a few UI and feed detection updates to it. It's free, and allows you to paste any website URL and it automatically searches for feeds via meta tags, fallback paths, and hardcoded feeds for some popular sites. It's also open-source(https://github.com/mratmeyer/rsslookup), has no ads, and doesn't track any URLs(uses Cloudflare Turnstile for abuse and Plausible for analytics). Max
