  • Ask HN: Website monitoring tool that will wake me up when site is down?
    This kinda sounds like the tool I built: OnlineOrNot (https://onlineornot.com) It sends reminder alerts over email and SMS (and phone calls soon) until the incident is resolved. It also integrates with PagerDuty/Opsgenie/Incident.io if you want something a bit more heavy duty. - Source: Hacker News / 6 days ago
  • Ask HN: What are you working on and why is it cool?
    Most folks here are probably tired of hearing about it, but I work on https://onlineornot.com Uptime monitoring (and status pages) for software teams. In my words, the aim is "monitoring that doesn't suck" - I've worked at companies with proactive monitoring like OnlineOrNot before, and was surprised how little the incumbents are innovating in the space. One customer once told me "f*k , all their system... - Source: Hacker News / 2 months ago

  • Ask HN: Those making $500/month on side projects in 2024 – Show and tell
    I'm coming up on three years of running OnlineOrNot (https://onlineornot.com) in 3ish weeks. In short, I wrote about React from my own perspective for a year (despite thousands out there doing the same thing), made money, and got inspired to do the same thing with an uptime monitoring tool (200th alternative to pingdom when I released it). I turned a tool I used for convincing contracting clients to not cheap out... - Source: Hacker News / 3 months ago
  • Ask HN: Those making $500+/month on side projects in 2024 – Show and tell
    I've been running OnlineOrNot (https://onlineornot.com) since early 2021 now (almost three years). I recently wrote about how this year it grew twice as fast as I expected: https://maxrozen.com/2023-focus-single-product-pays-off It all started because I needed a weekly report for my contracting clients to prove their web host sucked to the point where it was costing them significant money. They were paying for... - Source: Hacker News / 4 months ago

  • A simple server uptime monitor util
    It's for people who owns a log of servers/computers at home and need to monitor its uptime. For safety reason, it's impossible to expose the system to the public internet, we can only use the "push" strategy to report the up status. This tool is just for this purpose: request an URL at some interval repeatedly. Recommended to use this with uptime-kuma ( - Source: Hacker News / 8 months ago
  • Ask HN: How do you monitor your systemd services?
    Uptime-Kuma [1] with ntfy [2]. Most of my services expose HTTP so I just have Uptime-Kuma monitor that. But if you have something that is not exposed to the public you can still use a "push" type monitor, and in a cron job on your server(s), send heartbeat to it when everything is working.
