As much as I appreciate the attitude of building something from scratch instead of exploring existing solutions, the uptime/server monitoring is a super-saturated market and it's been like that since the 00s if not earlier.
That is, it will be really hard for you to find customers.
Completely agree - was surprised myself with the response we've received. Saturated market but the 10x cheaper/easier to set up seems to be resonating with other 1-3 person teams. Don't plan on bringing it to the enterprise-level though.
