Aider
Aider itself is completely free to use. It is open source software that you can download and use without any cost. There are no subscription plans or usage limits for the tool itself.
However, to use Aider, you need to connect it to an AI model through an API. These AI services charge based on usage. For example, using Claude or GPT-4 through their APIs costs money based on how many tokens (pieces of text) you process.
The actual cost depends on which AI model you choose. Some options like DeepSeek are very affordable, while others like GPT-4 cost more. You can also use free local AI models on your own computer if you prefer. The tool gives you full control over which AI service to use and how much to spend.
