AppSignal earns its place by bundling error tracking with a full APM toolkit under one plan. Errors come with debugging reports, real-time alerts, charts and custom tags, and can be sent to an issue tracker. The same account covers performance monitoring with slow query and N+1 query detection and memory leak detection, host metrics, metric dashboards, uptime checks from four locations with a free public status page, and check-ins for cron jobs. Every plan includes unlimited users, teams, applications and dashboards, and the free plan covers 30K requests, 1GB of logging and 5-day retention. AppSignal prices paid plans by request volume rather than error count, which suits steady web apps but takes some arithmetic to compare with event-priced trackers. From our location the pricing page shows euros only, so we have not listed a USD price.
