Getting started

How you install AppSignal depends on the language your application is written in. Every language has its own installation instructions, so start with your language in the languages section and follow the steps there. The two guides below cover the rest: adding your first application to AppSignal, and configuring it once it reports data.

Add your first application

Install AppSignal, send your first data, and see your application appear on AppSignal.com.

Configure your application

Add and change configuration options, per environment, in a config file or environment variables.

Application concepts

How applications, environments, and namespaces relate to each other.

How configuration works

The four options every application needs, and where each integration loads them from.
