AppSignal helps increase the performance of your Ruby applications. Track Ruby errors, improve ActionView performance, make Sidekiq jobs faster, and improve the overall stability and performance of your application.
Supported libraries
Monitoring for all Ruby frameworks & infrastructure.
You only need to install the Ruby gem. We’ll set up our Ruby performance monitoring and error tracking in minutes, with automatic data categorizing and graphing.
Ruby Performance Monitoring
Improve the performance of your Ruby codebase.
AppSignal gives detailed insights into the performance of specific parts of your infrastructure. Know exactly what was slow, and why it was slow. All performance insights are available out of the box, with endless possibilities to track performance metrics in depth.
ActiveRecord Performance
Monitor ActiveRecord queries & debug issues.
Get detailed breakdowns of your ActiveRecord performance, find slow requests, and debug the performance of your queries.
Sidekiq Performance
Sidekiq dashboards, metrics and alerts.
Get insights and alerts for Sidekiq queue lengths, Sidekiq throughput/performance per worker, Sidekiq process/connection counts and memory used in Redis.
ActionView Performance
Increase the rendering speed of ActionView.
Is your template rendering slow? We’ll show you exactly how long your ActionView rendering takes, so you can debug and improve performance.
N+1 Query Detection
Eliminate N+1 queries.
Find requests with the N+1 query antipattern, and increase the performance of your queries in Ruby.
Memory Allocations
Detect memory leaks in Ruby.
We track the number of memory allocations per event, so you can find out where your memory goes.
What our customers think
1500+ development teams rely on AppSignal to ship code with confidence. We are sharing a few of their stories with you.
Previously, we were using Honeybadger, Skylight, and Datadog, but now we have all those apps in one: AppSignal, and that is awesome!
Oleg, Developer at Benuevo
Hey y’all, we’re back. Sentry was just chaos.
Matt, Developer at Supertape
The biggest benefit of using AppSignal is the native Elixir support. … AppSignal just knows how an Elixir app is structured and builds error tracking and performance monitoring around it.

In New Relic, if you want more features, you have to upgrade… AppSignal’s pricing was easier to understand, and you get all the features for one price.
Devan Sabaratnam, Co-founder & CTO at HR Partner
Second to none support. It’s their developers themselves who are quickly and clearly answering any questions. It’s hard to overstate how nice this is.
