Each application in Bearer can have multiple environments associated with it. With your application selected, the Environments panel can be found in the Settings > General page.
Environments are automatically detected by the dashboard based on the Bearer Agent's configuration. The agent will do it's best to detect the environment name based on environment variables, like
NODE_ENV in Node.js. You can also manually set the environment by setting the
environment key as part of the configuration when initializing the Bearer Agent. For details on configuring the Bearer Agent, see the documentation for your stack's agent.
