UptimeRobot

UptimeRobot is the gold standard for indie hackers seeking straightforward uptime monitoring without enterprise pricing. Its generous free tier (50 monitors, 5-minute intervals) eliminates upfront costs while supporting HTTP(s), ping, port, and keyword monitoring across multiple regions. Paid plans start at just $7/month, making it accessible even for bootstrapped solo founders. Unlike Datadog's complex multi-service pricing structure, UptimeRobot's transparent, single-metric approach keeps costs predictable as your project grows.\n\nThe platform excels at rapid setup—add a URL and you're monitoring within seconds. Indie hackers love its simplicity: no agents, no configuration hell, just reliable alerts via email, SMS, Slack, or webhooks. Public status pages are included, so you can showcase reliability to users. The mobile app ensures you're never out of touch with your infrastructure.
