Overview
Scout APM, now branded Scout Monitoring, is an application performance monitoring tool founded in 2008 and headquartered in Denver, Colorado. It began with a strong focus on Ruby on Rails monitoring and has since expanded to support Python, PHP, Node.js, and Elixir applications.
The company is privately held with an estimated 11 to 50 employees, and its customers have historically included SaaS companies such as Expedia, Chargify, Liftopia, and MindBody. In June 2021, Scout added integrated error monitoring alongside its core performance tracing.
Key Features
Scout Monitoring tracks application traces, errors, and logs in a single dashboard, with particular strength in isolating N+1 database queries and memory bloat issues common in Rails and other web frameworks.
All plans, including the free tier, include unlimited users and unlimited monitored applications, with cost scaling purely by transaction volume, error count, and log storage rather than per-seat licensing.
Pricing
Scout offers a free plan with 300,000 monthly transactions, 5,000 errors, and 1 GB of logs, and a 'Production Ready' plan at $59/month (billed annually) or $98/month (billed monthly) with 1.2 million transactions and 30 GB of log storage.
Additional build-your-own tiers range from Startup at $19/month up to Large at $299/month based on transaction volume, with add-ons available for extra errors and log storage, plus a custom-priced Enterprise tier with SSO and SLA reporting.
Key Features
Application performance traces — Tracks response times and performance bottlenecks across Ruby, Python, PHP, Node.js, and Elixir applications.
N+1 query and memory bloat detection — Specialized detection for common performance issues like N+1 database queries and memory bloat.
Integrated error monitoring — Combines error tracking with performance traces in a single dashboard since its June 2021 expansion.
Log management — Centralized log storage and search alongside performance and error data.
