Installation
Get started quickly with aider-install
If you already have python 3.8-3.13 installed, you can get started quickly like this:
python -m pip install aider-install
aider-install
# Change directory into your code base
cd /to/your/project
# Work with Claude 3.5 Sonnet on your code
aider --model sonnet --anthropic-api-key your-key-goes-here
# Work with GPT-4o on your code
aider --model gpt-4o --openai-api-key your-key-goes-here
This will install aider in its own separate python environment. If needed, aider-install will also install a separate version of python 3.12 to use with aider.
Once aider is installed, there are also some optional install steps.
See the usage instructions to start coding with aider.
One-liners
These one-liners will install aider, along with python 3.12 if needed. They are based on the uv installers.
Windows
powershell -ExecutionPolicy ByPass -c "irm https://aider.chat/install.ps1 | iex"
Mac & Linux
Use curl to download the script and execute it with sh:
curl -LsSf https://aider.chat/install.sh | sh
If your system doesn’t have curl, you can use wget:
wget -qO- https://aider.chat/install.sh | sh
Install with uv
You can install aider with uv:
python -m pip install uv # If you need to install uv
uv tool install --force --python python3.12 aider-chat@latest
This will install uv using your existing python version 3.8-3.13, and use it to install aider. If needed, uv will automatically install a separate python 3.12 to use with aider.
Also see the docs on other methods for installing uv itself.
Install with pipx
You can install aider with pipx:
python -m pip install pipx # If you need to install pipx
pipx install aider-chat
