   I'm trying to disrupt the insane pricing of uptime monitoring. I hope you'll help me out. I'm trying to create the absolute cheapest dev monitoring tool on the market, while still being competitive with all the others. This means $3/month plan, while still having monitoring for: Website, REST API, UDP/TCP, ICMP, Heartbeat/CRON, WS/WSS, DNS, Domain Intel/expiry and SSL. Everything with unlimited alerts through webhooks. I'm also taking an unlimited approach to the amount of checks you can have. I'd love to hear your thoughts.
