Best Cheap Uptime Monitoring in 2026
For uptime and visual monitoring on one website under $20 a month, Visual Sentinel Solo costs $15 ($153 billed yearly) and checks uptime every 5 minutes and screenshots every 30 minutes. For uptime checks alone, UptimeRobot Free, Visual Sentinel Free, and self-hosted Uptime Kuma have $0 options. The comparison below is source-dated and keeps billing period, monitor allowance, schedule, evidence, and operating responsibility distinct.
Uptime and Visual Monitoring for One Website Under $20 a Month
Visual Sentinel Solo is the only paid plan in this table under $20 a month whose pricing lists both uptime checks and screenshot comparison. Uptime-first tools such as UptimeRobot do not list visual checks, and change-detection tools such as Visualping, PageCrawl, and Distill do not list uptime checks. If the budget is $0, you can pair UptimeRobot Free with Visualping Free, at the cost of two dashboards and two sets of alerts.
