Open-Source vs. Closed-Source Considerations

Closed-Source Advantages:

• Convenience and reliability with minimal setup
• Vendor support and ecosystem integration
• Often powered by more advanced models (GPT-4, Claude, etc.)

Open-Source Advantages:

• Code data stays on premises if self-hosted
• Greater transparency and customization options
• Often free or lower cost at scale
• No vendor lock-in

Many enterprises adopt a hybrid approach, using commercial tools for general coding and open-source options for sensitive projects that cannot leave their network.
