What it does
StayUp.dev is a tiny tool I built after Cloudflare's outage cooked our monitoring. Instead of another ping tool, it actually tells you why your site looks down - origin dead, CDN failing, DNS slow, SSL expiring, etc. Free diagnostic tool, plus £9/mo monitoring + instant alerts if Cloudflare/CDN breaks.
Free CDN vs server diagnostic tool. Paid plans from £9/month (10 domains) with 1-minute checks, instant Email/Slack/Discord alerts, and public status pages.
Other tools say "Your site is down." We tell you it's Cloudflare's Bot Management breaking, your SSL cert expired yesterday, or DNS is failing in EU only. Skip the guessing. Don't waste time guessing. Know exactly where the failure occurred. Detect Cloudflare, Vercel, AWS, and 20+ CDN providers. Know if it's your origin or the edge. Monitor certificate expiry, validation, and handshake times to prevent security issues. Track DNS lookup, response times, and content load speeds to optimize performance. Automated checks every 60 seconds. Catch issues before your customers notice. Email, Slack, and Discord notifications the second something goes wrong. Branded status pages with live uptime…from stayup.dev

Keep – GitHub Actions for your monitoring tools2023 · github.com · ▲181Hi Hacker News! Shahar and Tal from Keep here. A few months ago, we introduced here at HN (https://news.ycombinator.com/item?id=34806482) Keep as an “open source alerting CLI” and got some interesting feedback - mainly around UI, automation, and supporting more tools. We were VERY early back then, and we understood that although the current DX around creating alerts is not great, it's not that critical and developers don’t need another tool just for that. But we did find something else. While talking to developers and devops, we found that a lot of companies use many tools…

Talanoa▲346Hi 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…
