What it does
Tell Me When Down watches your site at three depths — a free security scan of your public URL (SSL, headers, DNS, spoofing), a read-only GitHub App that finds CVEs and leaked secrets in your code, and an SDK for your DB, Stripe webhooks and cron jobs. You don't need to understand the findings — every one comes with a ready-to-paste fix. Hit "Copy for your AI tool" and the same agent that built your app fixes it. Uptime checks every 60s, plain-English alerts. Built for solo founders.
Free website security check, plus uptime monitoring every 60 seconds from three regions. SSL certificate expiry, cron job and Stripe webhook monitoring — with plain-English alerts, built for solo founders shipping with AI tools.
Paste a URL and check your website's security in seconds — SSL, security headers, DNS, exposed files. No signup. Then let us keep watching: uptime checks every 60 seconds from three regions, and a plain-English email when something breaks. You were asleep, or deep in a prompt shipping the next feature. Meanwhile a deploy quietly took the site down and every visitor hit a blank page for five and a half hours. We can't stop the outage. But when your website is down, you should be the first to know — not the last. Website monitoring built for small sites and side projects: paste a URL and we check it every 60 seconds from three regions. You only hear from us when a real outage is confirmed —…from tellmewhendown.com

Talanoa▲340Hi 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…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
