FAQ.
Can I still use UptimeRobot for free commercially?
UptimeRobot restricted free-tier commercial use in 2024. Their Solo plan starts at $7/month for uptime-only monitoring. BlackSight's free tier allows commercial use and the $9/month Light plan adds 16 security scanners on top of uptime.
What does BlackSight have that UptimeRobot doesn't?
UptimeRobot is uptime-only. BlackSight bundles uptime monitoring with vulnerability scanning, SSL monitoring, security headers, DNS analysis, email authentication, supply chain monitoring, credential leak detection, and 10 more scan types in one dashboard.
Is BlackSight more expensive than UptimeRobot?
At the entry level, they are comparable: UptimeRobot Solo is $7/month, BlackSight Light is $9/month. But BlackSight Light includes all 17 scanners, not just uptime — so you replace multiple tools at once.
Can I migrate from UptimeRobot to BlackSight?
Yes. Sign up for a free BlackSight account, add your domains, and enable uptime monitoring. You can run both tools in parallel during migration. No data import is needed — BlackSight scans your sites independently.
