Application Performance Monitoring allows developers to monitor and analyze the performance of any Ruby or Ruby-based framework project. It collects key data about the performance issues and trends, bottlenecks, and also unexpected behavior of the application and provides actionable insights in a human-readable manner.

Many APM solutions are available as a part of bigger SaaS observability suites, but there are also a lot of standalone, language-specific tools ranging from lightweight code profilers and powerful open-source solutions. Let's take a look at some of the Best Ruby Application Performance Monitoring Tools in 2023.

1. Better Stack

Better Stack Logs Dash
Better Stack offers a structured log management platform based on ClickHouse. It allows you to start collecting, analyzing, and visualizing logs in real-time. Better Stack easily collects data directly from any Ruby on Rails, Sinatra, and plain Ruby project. Better Stack's advanced built-in collaboration features, resource-efficient ClickHouse, and visually pleasing, dark-mode UI help you to spend less time debugging and focus on shipping higher-quality software faster.

Better Stack Logs is a part of the Better Stack ecosystem, and together with Better Stack Uptime, they create a complete observability solution with incident management built-in. With one-click Better Uptime integration, you can easily alert on-call team members of any irregularities in your application's behavior. Be it a specific log message error or a predefined usage trend.

Sensu Go also automatically handles monitoring of multi-cloud environments.

8. Sentry

Sentry Dash
Sentry's performance monitoring offers support for various application languages and frameworks and is available both as a SaaS and Self-hosted platform.

Sentry offers end-to-end distributed trace monitoring to trace performance issues to their origin.

9. Datadog

Datadog APM
Datadog is one of the most popular and successful monitoring solutions available. Datadog's APM tool monitors apps across browsers, platforms, databases, or lines of code. It works well with frontend and backend monitoring data and reports on performance-related issues, dependencies, health, and business metrics.

Datadog works best as a part of the full Datadog stack, is enterprise-ready, and belongs among the most expensive solutions available.

10. Elastic APM

Elastic APM
Elastic APM automatically sets up error logging and performance tracking by their elastic gem.

Elastic APM is built upon the ELK stack. It's composed of open source libraries for collecting performance data, a server, receiving performance data, Elasticsearch, and Kibana for visualization.

11. ScoutAPM

ScoutAPM monitors the performance of the Ruby on Rails application using the scout Ruby gem. It automatically monitors the performance of controller actions, records transaction traces, and instruments many Ruby libraries, including ActiveRecord, Net::HTTP, or Redis.

ScoutAPM also supports Ruby frameworks such as Sinatra, Delayed Job, Resque, and Sneakers.

12. Prometheus

Prometheus Grafana
Prometheus is an open-source monitoring and alerting set of tools built by SoundCloud's engineers in 2012. It was the second CNCF project after Kubernetes, and it has managed to obtain a large and vibrant community of contributors and users ever since.

13. Atatus

Atatus offers instant insight into Ruby applications and frameworks. It enables end-to-end visibility, API failure monitoring, tracking application errors and exceptions, tracing transactions, monitoring external requests, database performance, and much more.

Atatus also offers auto instrumentation for the most popular frameworks, enables smart notifications, compare the impact of different code versions, and is fully scalable.

14. SigNoz

Signoz Dash
