AppSignal vs SeaLion: What are the differences?

Developers describe AppSignal as "Monitoring for Ruby and Elixir. By developers, for developers". AppSignal gives you and your team alerts and detailed metrics about your Ruby or Elixir application Sensible pricing, no aggressive sales & support by developers.. On the other hand, SeaLion is detailed as "Quickly diagnose problems with your Linux servers". SeaLion is a cloud based system monitoring tool for Linux servers. Getting started is as easy as executing a command. It installs an agent at /usr/local/sealion-agent and runs as an unprivileged user (sealion). This agent will collect data at regular intervals across servers and this data will be available on your workspace. The latest version is shipped with 5 default services namely Apache, NGINX, MongoDB, MySQL, Redis.

  • Track errors
  • Performance Monitoring
  • Compare deploys. Monitor background jobs.

On the other hand, SeaLion provides the following key features:

Coming from a Ruby background, we've been users of New Relic for quite some time. When we adopted Elixir, the New Relic integration was young and missing essential features, so we gave AppSignal a try. It worked for quite some time, we even implemented a :telemetry reporter for AppSignal . But it was difficult to correlate data in two monitoring solutions, New Relic was undergoing a UI overhaul which made it difficult to use, and AppSignal was missing the flexibility we needed. We had some fans of Datadog, so we gave it a try and it worked out perfectly. Datadog works great with Ruby , Elixir , JavaScript , and has powerful features our engineers love to use (notebooks, dashboards, very flexible alerting). Cherry on top - thanks to the Datadog Terraform provider everything is written as code, allowing us to collaborate on our Datadog setup.
