My website gets more attacks than human visitorshttps://news.ycombinator.com/item?id=48677487I run a small self-hosted website on a Raspberry Pi 4B at home. A few weeks ago I started wondering: who actually visits a website in 2026? Not just humans. Everything. So I built a public observability dashboard on top of GoAccess that separates traffic into four categories: human visitors, search engine crawlers, AI retrieval agents, and automated attacks. The numbers from the last 17 days surprised me:4,523 human visits 6,409 automated attack attempts Thousands of crawler requests from search engines and AI systemsThe attacks aren't sophisticated. They're mostly automated scanners probing for .env files, WordPress admin panels, and cloud credentials — hitting every public IP on the internet regardless of what's actually running there. What I found more interesting was the AI agent behavior. AI retrieval agents (GPTBot, ClaudeBot, PerplexityBot, Amazonbot) behave differently from traditional search crawlers. They hit semantic files aggressively — llms.txt, sitemap.xml, JSON-LD struct

Show HN: Open-source general-purpose alternative to Exa Websetshttps://github.com/tinyfish-io/bigsetHey Everyone!So I get to spend most of my day tweaking and playing around with really powerful search engines at TinyFish (which is so awesome). I’ve recently been super fascinated by the idea of using a search engine recursively to build datasets.Been playing around with Exa’s WebSets product quite a bit and realized it was mainly focused on prospecting, and it creates datasets with a lot of missing data.So we built a fully open source project, that can build and update datasets on any topic.Datasets I have generated so far, “All products that Starbucks sells on amazon, with their price and if they are in stock”, “All theme parks in California, with ticket prices” , “All YC companies that are currently hiring for eng roles with their hiring page link” Would love for yall’s to try it out, and drop your thoughts, stars and feedback. Thanks!

Show HN: Monochess – A chess variant with rule-bending action cardshttps://monochess.pages.devHey HN,A while back I saw a video[0] of people playing chess but using action cards to modify the rules mid-game (skip turns, reverse, draw 2, etc.). It looked incredibly chaotic and really fun to play, so I decided to actually build it as a playable online game. A small difference in Monochess is there's no need to call out a phrase if you just have one piece. I noticed while testing with the mrs. it became really annoying to keep doing this every move.That also gave me a really good reason to build on Cloudflare using their entire stack, something I've been meaning to get my hands dirty with for quite some time. The app is built using SvelteKit and hosted on Pages, there's a Durable Object worker-backed game server, and D1 as the database layer for accounts/games.This project included:- A Custom Engine: Standard chess engines panic when forced into illegal board states. The engine wraps standard chess logic to allow for mid-turn state changes—handling concepts like rolling back a com

Musk praises “epic” Super Heavy-Starship launchhttps://spaceflightnow.com/2026/05/23/musk-praises-epic-super-heavy-starship-launch/The Starship upper stage was equipped with six third-generation Raptor engines and one of three optimized for operating in vacuum shut down early during the climb to space. The flight computer kept the other five engines running longer than originally planned to make up for the shortfall, putting the craft on an acceptable sub-orbital trajectory.

Show HN: Helm Terminal – Free portfolio intelligence that tells you what to dohttps://helmterminal.devHi HN,I'm the solo founder of Helm Terminal (helmterminal.dev). It's a free portfolio analytics tool that connects to your accounts via Plaid and surfaces actionable insights and intelligence. Concentration risk, tax-loss harvesting, earnings exposure, idle cash, sector drift, etc. Automatically, every day.Every other portfolio tracker/brokerage I've tried showed me balances and pie charts but never informed me what to do or what was going on. I'd check my accounts, see things were generally "fine", and move on. Then I realized I'd been sitting on thousands of dollars in unharvested tax losses, 60%+ of my portfolio was exposed to tech, and I didn't know half of my positions were reporting earnings soon.Helm is the tool I built to fix all of these issues, and a tool I wish existed. It runs on a set of intelligence engines on top of your connected accounts and gives you a prioritized inbox of things worth doing, as well as news tailored to your holdings worth looking at.

Show HN: PulseTech.news – an automated, privacy-first tech aggregatorhttps://pulsetech.news/I built PulseTech.news because I was tired of "heavy" tech news sites. I wanted a lightning-fast, zero-bloat aggregator that I could check in 30 seconds to get the global pulse.Technical Highlights:* Performance: Built on a lean PHP/MySQL stack for sub-100ms page loads. No heavy frameworks, just vanilla performance. * Automation: A headless background scraper (bin/scrape.php) runs on an hourly cron cycle to digest, categorize, and deduplicate headlines from the world’s top tech sources. * Privacy-First: Implemented Google Consent Mode v2 and PII-free click tracking to be fully GDPR/CCPA compliant without compromising analytics. Semantic Web: Every listing is backed by dynamic JSON-LD ItemList schemas, making the site highly discoverable by search engines. * I’ve spent the last few days fine-tuning the automated categorization engine to ensure that "AI" news stays in AI, "Cybersecurity" stays in security, etc., based on a weighted keyword detection system.I'd love to hear your feedback

It will fire the starting gun on a race that Washington and Beijing still insist does not exist and pull Elon Musk's SpaceX into the center of a contest that blends geopolitics, markets and myth. For two years, NASA has framed Artemis as

Show HN: Craigslist Car Shopping Chrome Extension with KBB and AI Insightshttps://chromewebstore.google.com/detail/carbuddy-talk-to-cars-wit/aglpplbhdlccaekjbajdgfbjlbgmeageDuring my exchange in Berkeley, my friends and I decided to share a few cars amongst ourselves. Car shopping was fun at first, until you realize how tedious it is to have to constantly look up the fair valuation with a price advisor like Kelley Blue Books (KBB) for every single car (easily >30% of the time spent shopping).We were also novices when it came to cars and didn’t know what to look out for. As a result, after less than a month of use, one of our car’s engines completely stopped while I was on the way home from school on the highway. Thankfully there were no accidents or injuries, but it was a harrowing experience nonetheless and the administrative headaches that followed were a huge pain.These experiences and pains is what led me to create Car Buddy, an AI-powered chrome extension that gives you the fair value of the car in-page on the car listing itself, but also lets you “talk to the car”. It gives you insights and warnings of common issues faced and acts as a personalized
