Scout APM

What Scout APM is

Scout APM is a cloud monitoring and observability platform from Zimuth, Inc. for engineering teams investigating application performance problems. It brings traces, metrics, logs, error tracking, and alerting into one platform. Scout lists agents for Ruby, Python, PHP, Elixir, and Node.js. It detects slow database queries and N+1 patterns and provides query analysis. Its anomaly detection learns the normal behavior of each endpoint and alerts when performance patterns change, without requiring configured thresholds. Scout also provides an MCP server, CLI, and API so AI coding agents can access production errors, traces, and performance data. Listed integrations include Slack, PagerDuty, Splunk On-Call, Opsgenie, Discord, Zapier, webhooks, Rollbar, Sentry, Honeybadger, Bugsnag, and GitHub. The Free plan includes 300K monthly transactions, 1 GB of log data, 5,000 errors, one endpoint monitored for anomalies, and unlimited users and apps. Paid options start at $19 a month, and a 14-day trial is available. Every plan includes human support; paid plans have priority response times, and Enterprise includes dedicated premier support. Scout states that it is SOC 2 Type II certified, encrypts data at rest and in transit, and conducts annual third-party penetration testing.

Who it suits

Scout APM suits engineering teams working with Ruby, Python, PHP, Elixir, or Node.js that need to investigate application performance and errors. Its free tier can fit teams starting with modest monitoring limits, while Enterprise offers custom transaction volume and compliance-related options.

Limits

The Free plan allows 300K monthly transactions, 1 GB of log data, 5,000 errors, and one endpoint monitored for anomalies. When a plan’s monthly transaction limit is exceeded, Scout continues monitoring but stops recording new transactions in the dashboard.

Getting started

1. Visit Scout’s website and choose the Free plan or a paid plan.
2. Use the 14-day trial if you want to try a plan before choosing.
3. Connect an agent for Ruby, Python, PHP, Elixir, or Node.js.
4. Configure integrations such as Slack, PagerDuty, webhooks, or GitHub as needed.
5. Use Scout’s API, CLI, or MCP server to give AI coding agents access to production performance data.

Verdict

Pick Scout APM if your team wants application monitoring that combines performance data, errors, and alerts, with agents for its listed languages. The free plan provides a way to start, and paid plans begin at $19 a month. Look elsewhere if distributed tracing is essential or your usage exceeds plan transaction limits without recording interruption.
