GitHub Copilot changed how developers write code, but at $19/month, it's not for everyone. Whether you're looking for something free, more private, or with different features, here are the best Copilot alternatives in 2026.
Why Look for Copilot Alternatives?
Developers switch from Copilot for several reasons:

- Privacy: Code sent to Microsoft/OpenAI servers
- Features: Need capabilities Copilot lacks
- Model preference: Want Claude or other AI models
- IDE limitations: Need support beyond VS Code/JetBrains
