Frequently Asked Questions
Is AlertSleep's free uptime monitoring plan really free?
Yes — completely free with no expiration date, no credit card required, and no hidden limits beyond the plan features. AlertSleep's free plan includes 5 monitors, 5-minute check intervals, email alerts, multi-location checks, and 1 public status page. It never expires and you will never be automatically charged.
What is the best free website uptime monitoring tool?
AlertSleep, UptimeRobot, and Freshping are the most widely used free uptime monitoring tools. AlertSleep offers 5 monitors with email alerts and a status page. UptimeRobot offers 50 monitors but no phone call alerts on any plan. Freshping offers 50 checks from 10 global locations. AlertSleep stands out for including a public status page and SSL monitoring on the free tier.
How many websites can I monitor for free?
AlertSleep's free plan includes 5 monitors — each monitor watches one URL (website, API endpoint, or server). You can monitor your main site, a staging environment, and critical API endpoints simultaneously. If you need more than 5 monitors, paid plans start at $5/month for 20 monitors with 1-minute check intervals.
What is the check interval on the free plan?
The free plan checks each monitor every 5 minutes. This means your site could be down for up to 5 minutes before detection, plus alert delivery time — giving a total response window of 6–8 minutes. Paid plans check every 1 minute, reducing detection time to 1–3 minutes. For personal projects or low-traffic sites, 5-minute intervals are typically sufficient.
Does free uptime monitoring include SSL certificate monitoring?
Yes. AlertSleep's free plan includes SSL certificate expiration monitoring. You will receive email alerts 30, 14, and 7 days before your SSL certificate expires, preventing the browser security warnings that destroy user trust and hurt search rankings. This is included at no cost on all plans.
What is a free uptime checker?
A free uptime checker is a tool that automatically tests whether your website is accessible and responding correctly. It sends periodic HTTP requests to your URL, verifies the response, and alerts you when the site is unreachable. AlertSleep's free uptime checker runs continuously in the background — unlike one-time check tools, it monitors 24/7 and sends alerts when problems occur.
Can I use free uptime monitoring for a business website?
Yes for small businesses and solo operators — the free plan covers a main site, checkout page, and API endpoint simultaneously. However, if your site generates revenue, consider upgrading: the free plan uses 5-minute check intervals (vs. 1-minute on paid plans) and email-only alerts (no SMS or phone calls). For e-commerce or SaaS with paying customers, the $5/month Starter plan is typically worth the cost to catch downtime faster.
What does free uptime monitoring not include?
AlertSleep's free plan does not include: SMS alerts, phone call alerts, check intervals faster than 5 minutes, more than 5 monitors, more than 1 status page, data retention beyond 7 days, or more than 1 team member. These features are available on paid plans starting at $5/month.
