OnlineOrNot
We keep a close eye on your websites, APIs, cron jobs, and other scheduled tasks. Your team receives instant notifications through various channels, including email, SMS, Slack, PagerDuty, and Incident.io. You don’t need to be a tech expert to get started, as our setup is straightforward and user-friendly. Enjoy peace of mind with monitoring that helps you sleep easier at night. Checks can be performed as frequently as every 30 seconds, allowing you to identify problems that could temporarily disrupt your website. Each check can be customized with specific HTTP methods, headers, and bodies according to your needs. OnlineOrNot ensures reliability by conducting each check at least twice before notifying you, with the possibility of additional checks if required. Furthermore, OnlineOrNot monitors your SSL certificates for any impending expirations or potential issues and promptly alerts you if something goes awry. You have the option to perform uptime checks from a single region or multiple locations simultaneously. Since your customers depend on your services, keep them informed with a dynamic status page that updates automatically. You can easily add your customers as subscribers to this status page and send regular updates about any incidents via email to keep everyone in the loop. This proactive approach not only enhances customer trust but also improves overall service reliability.

UptimeMonk
Know when a customer-facing service, API, or background job fails, then get the evidence needed to respond. UptimeMonk combines website uptime monitoring, API monitoring, network checks, certificate tracking, cron monitoring, and incident investigation in one workspace. Teams can check HTTP and HTTPS endpoints, rendered public web pages, SSL/TLS certificates, domain registrations, DNS records, TCP ports, ICMP reachability, and secure heartbeat URLs for scheduled jobs.
Checks run from multiple regions and can use a second location to confirm a failure before creating an incident. Each incident brings together probable-cause guidance, regional observations, latency, an evidence timeline, alert history, and recovery details. Service dependency mapping shows which monitored systems rely on others. Critical paths, cross-monitor incident correlation, and evidence-linked impact summaries help responders understand whether an upstream outage may be affecting downstream services without presenting correlation as proven causation.
Signed GitHub and GitLab deployment webhooks place relevant release events beside incidents without giving UptimeMonk access to source code. Teams can publish branded status pages with live service state, recent incidents, maintenance announcements, and availability history. Scheduled maintenance suppresses expected alerts while preserving check evidence. Email, Slack, Microsoft Teams, Discord, webhooks, PagerDuty, Opsgenie, push notifications, on-call rotations, role-based access, audit history, SLA reporting, and CSV exports support day-to-day operations.
