Config with .env

You can use a .env file to store API keys and other settings for the models you use with aider. You can also set many general aider options in the .env file.

Aider will look for a .env file in these locations:

• Your home directory.
• The root of your git repo.
• The current directory.
• As specified with the --env-file <filename> parameter.

If the files above exist, they will be loaded in that order. Files loaded last will take priority.

Sample .env file

Below is a sample .env file, which you can also download from GitHub.
