    Statusduck – Website monitoring tool where the data is public▲78

    Hello HN! We're excited to share Statusduck, an uptime monitoring tool where the data is publicly viewable. There are an uncountable amount of uptime tools but we thought we'd put a fun spin on the concept by making another one where people can immediately set up a monitor without signing up. Just type in a website and our service will start pinging it every minute!
