Uptime This Week
Both Calendly and Monday.com delivered flawless uptime at 100% during the monitoring week, with zero recorded incidents or downtime events. This equal performance reflects mature infrastructure in the collaboration tools category, where both providers have invested in redundancy and failover mechanisms. For mission-critical scheduling and project management workflows, both services proved equally dependable during this period.
Response Time
Calendly's average response time of 147ms was substantially faster than Monday.com's 299ms—a 152ms difference that compounds across thousands of user interactions daily. While both response times fall within acceptable ranges for web applications, Calendly's performance advantage may translate to noticeably snappier user interfaces, particularly for users in regions farther from primary infrastructure.
Incidents & Downtime
No incidents occurred for either provider during the monitoring window. Both services operated without service degradation, API errors, or component failures. This clean record reflects consistent operational discipline, though a single week provides limited insight into incident frequency patterns across larger timeframes.
Which Should You Choose?
Choose Calendly if response speed and scheduling-focused workflows are priorities, or Monday.com if you require broader project management capabilities—both are equally reliable. For latency-sensitive use cases or users in high-latency regions, Calendly's 147ms response time provides a meaningful advantage. Organizations should validate performance with their own geographic locations and traffic patterns before final selection.
