Frequently Asked Questions

How does Aider compare to Cursor?

Aider is terminal-based with any model support and pay-per-use pricing. Cursor is GUI-based with built-in models and $20/month subscriptions. Choose Aider for command-line workflows and model flexibility, Cursor for visual IDE experience.

What do API costs look like in practice?

Light developers spend $10-30/month, heavy users $50-100/month. A typical session costs $0.50-$2 with Claude, $0.02-$0.10 with DeepSeek. No built-in cost tracking means monitoring your API dashboard is essential.

Can I use local models?

Yes, through Ollama or LM Studio. Requires 16GB+ RAM. Local models produce lower quality edits than Claude or GPT-4o, especially for complex changes.

Does it work with large codebases?

Works well under 50K lines. Larger projects hit context limits. Consider Sourcegraph Cody for massive codebases with better context management.
