Show HN: ArkWatch – Uptime monitoring with zero dependencies https://ift.tt/pRkjJZ1

Show HN: ArkWatch – Uptime monitoring with zero dependencies I'm a solo dev, and I got tired of signing up for monitoring services that require installing agents, browser extensions, or wiring up Slack/PagerDuty just to know if my side project is down. So I built ArkWatch: a free uptime monitoring API with zero dependencies. No SDK, no npm package, no webhook setup. Just curl + your email. One command to start monitoring: curl -X POST https://ift.tt/qdFvDBH \ -H "Content-Type: application/json" \ -d '{"url":"https://yoursite.com","email":"you@example.com"}' That's it. Your URL gets checked every 5 minutes. If it goes down, you get an email. No dashboard to check, no account to manage, no vendor lock-in. It also has an AI layer (Mistral) that summarizes what actually changed on a page – useful for tracking competitor pricing or changelog updates. But the core use case is dead-simple uptime alerts. Stack: Python/FastAPI, hosted on Hetzner EU. Free tier: 3 URLs, 5-min checks. Paid starts at €9/month for more URLs and faster intervals. I'd love feedback from HN – especially on what you'd want from a zero-dependency monitoring tool. Try it, break it, tell me what's missing. February 9, 2026 at 12:39AM
