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.
GitHub Copilot
GitHub Copilot offers flexible pricing plans for different user types. The Free plan provides 2,000 code completions and 50 chat requests monthly, perfect for trying out the service. Individual developers can upgrade to Copilot Pro at $10 per month or $100 annually, which includes unlimited completions and access to premium AI models.
For power users, Copilot Pro+ costs $39 per month or $390 yearly and offers 1,500 premium requests monthly with access to the latest AI models including GPT-4.5 and Claude Opus 4.
Business teams can choose Copilot Business at $19 per user monthly with team management features, while Enterprise customers pay $39 per user monthly for advanced security, compliance tools, and custom model access.
