Optional steps

The steps below are completely optional.

Store your api key (optional)

You can place your api key in an environment variable:

Or you can create a .aider.conf.yml file in your home directory. Put a line in it like this to specify your api key:

openai-api-key: sk-...

Enable Playwright (optional)

Aider supports adding web pages to the chat with the /web <url> command. When you add a url to the chat, aider fetches the page and scrapes its content.

By default, aider uses the httpx library to scrape web pages, but this only works on a subset of web pages. Some sites explicitly block requests from tools like httpx. Others rely heavily on javascript to render the page content, which isn’t possible using only httpx.

Aider works best with all web pages if you install Playwright’s chromium browser and its dependencies:

playwright install --with-deps chromium

See the Playwright for Python documentation for additional information.

Enable voice coding (optional)

Aider supports coding with your voice using the in-chat /voice command. Aider uses the PortAudio library to capture audio. Installing PortAudio is completely optional, but can usually be accomplished like this:

Add aider to your editor (optional)


joshuavial provided a NeoVim plugin for aider:

VS Code

joshuavial also confirmed that aider works inside a VS Code terminal window. Aider detects if it is running inside VSCode and turns off pretty/color output, since the VSCode terminal doesn’t seem to support it well.
