What is AppSignal?

AppSignal is a developer first monitoring platform from Amsterdam that combines application performance monitoring, error tracking, host monitoring, uptime monitoring, and log management in a single dashboard. It measures response time breakdowns and 90th percentile performance across an application, tracks CPU, memory, disk, and network usage on each host, and uses anomaly detection to flag unusual metric behavior before it becomes a bigger problem. Check-ins let teams monitor scheduled jobs and cron processes.

AppSignal offers a free plan covering 50,000 requests a month with 1GB of logging, and paid plans starting at about $23 a month for 250,000 requests, scaling up to $239 a month for 25 million requests. Every plan, including the free one, includes unlimited applications, hosts, and team members, and alerts can be routed to Slack, GitHub, PagerDuty, and other tools.
