Scout APM helps engineering teams quickly identify and fix performance bottlenecks in Ruby, Python, Elixir and PHP applications. Track slow endpoints, database queries, memory issues, and errors with detailed transaction traces and actionable insights that pinpoint exactly where problems occur. Combines performance monitoring, error tracking, and log management in one platform without the complexity of enterprise APM tools.

Overview
Scout APM monitors application performance, tracks errors, and manages logs for Ruby, Python, Elixir, and PHP applications. The client side agent automatically instruments your framework to collect transaction traces, surface N+1 queries, detect memory bloat, and identify slow database calls. You get percentile-based metrics for each endpoint along with detailed traces showing exactly where time is spent in requests.
Error monitoring groups exceptions automatically and provides full context for each occurrence including request parameters, environment data, stack traces and custom context. When configured with GitHub integration, backtraces link directly to the relevant code. Logs can be viewed alongside performance data and errors to see the complete picture when diagnosing issues. Performance data, errors, and logs are correlated by request to make troubleshooting faster.
The monitoring agent runs in your application process with minimal overhead. The minimal setup involves adding a package and deploying with a configuration file or environment variables. Deployment markers, commit tracking, and customizable alerts help connect performance changes to specific code releases. The interface focuses on the metrics that matter for application performance: response times, throughput, error rates, and resource consumption.
Highlights
- Automatic instrumentation for Ruby, Python, Elixir and PHP, while capturing transaction traces, detecting N+1 queries, slow/long lasting queries, as well as identifying memory bloat
- Performance monitoring, error tracking, and log management all in one tool - Correlates traces, exceptions, and logs for faster troubleshooting
- Low overhead agent with minimal setup required

Dimension | Description | Cost/month |
|---|---|---|
Scout APM Transactions | 1.5M APM web and job transactions per month | $40.00 |
Scout Error Monitoring | 50K Errors captured per month | $20.00 |
Scout Log Management | 30Gb ingested log records per month | $40.00 |
Dimensions summary
This listing offers three independent usage-based dimensions you can subscribe to under a contract. Scout APM Transactions covers 1.5M web and job transactions per month. Scout Error Monitoring captures 50K errors per month. Scout Log Management ingests 30Gb of log records per month. Each dimension is billed separately by its own unit, so you pick the volumes your application needs. The dimensions are not tiers of one product. Instead, they combine to monitor performance, errors, and logs together. You can add capacity across these dimensions as your usage grows.
Top-of-mind questions for buyers
A transaction is a single web request or one background job execution that Scout traces. Each traced request or job counts as one transaction. You can ignore specific requests or sample based on probability to control the count. This applies to the 1.5M monthly transaction allotment.
Scout keeps monitoring your application but stops recording new transactions in the dashboard once you pass the monthly limit. Recording resumes at the start of the next billing cycle. You can raise your capacity anytime to increase the limit rather than wait.
The three dimensions bill independently and appear on one invoice. Transactions, errors, and log volume each meter separately. If log ingestion passes 30Gb in a cycle, added storage is billed in arrears as on-demand usage per gigabyte, so you do not lose log data.

Real User Here: They give us unmatched SQL Visibility That Pinpoints Slow Queries Fast
Reviewed on May 30, 2026
Review provided by G2
What do you like best about the product?
The SQL-level visibility is unmatched. When something goes wrong, Scout connects surface-level symptoms directly to the exact query causing the problem — N+1 detection, slow queries, the works. Nothing else in our stack does this. These saved us multiple times...
What do you dislike about the product?
The only thing we'd change is having more excuses to talk to their team. Great product, great people. Seriously, their people are amazing. They run a tight ship.
What problems is the product solving and how is that benefiting you?
Without Scout, database-layer issues are invisible until users feel them. Scout gives us the visibility to catch and fix performance problems before they become incidents — especially critical for our booking and scheduling system where downtime or slowness has real consequences for medical practices. We can't afford this and will never be replacing them.

Powerful Rails Insights, But the UI Needs a Modern Refresh
Reviewed on May 13, 2026
Review provided by G2
What do you like best about the product?
Scout is built for Ruby and Rails rather than retrofitted onto it, and that focus shows up everywhere. Install is three lines in the Gemfile, a config file, and a deploy. You're looking at real data in about five minutes. N+1 detection and slow-query analysis are the killer features for any Rails app. Scout points you straight at the offending controller action and ActiveRecord call pattern, so you can land a fix in one pass. App traces give per-request code-level visibility that's been useful for chasing down regressions after deploys. Pricing is realistic for small and mid-sized teams in a way the Datadog and New Relic tier just isn't.
What do you dislike about the product?
The UI is the main thing keeping this from a 5. It feels at least one generation behind where modern observability tooling has landed. Navigation is still mostly link-and-page-load rather than the fast, filterable, drill-down interactions you get from newer tools. Time-range manipulation, faceted filtering, and dashboard composition could all be much more interactive. None of this affects the quality of the underlying data Scout collects, but a UI/UX refresh would be the biggest single improvement they could ship.
What problems is the product solving and how is that benefiting you?
Pinpointing N+1s and slow ActiveRecord queries before they turn into production incidents, and shortening the path from "something looks off" to "here's the line of code." Having traces, errors, and logs correlated in one place cuts context-switching during incidents. For a Rails-heavy stack, it's deeply integrated, and so it gives a better signal-to-noise ratio than the general-purpose APM vendors, with a fraction of the configuration overhead.
