AI Code Editors 2026: Cursor vs Windsurf vs GitHub Copilot
This article is written in English. Our training modules are available in French.
The landscape of AI-assisted coding has evolved dramatically. What started with GitHub Copilot's autocomplete has expanded to full-fledged AI-native integrated development environments that can understand entire codebases, execute complex refactors, and write applications from natural language descriptions. In 2026, three platforms dominate developer mindshare: Cursor, Windsurf, and GitHub Copilot.
This comprehensive comparison examines each platform's strengths, limitations, and ideal use cases to help you choose the right AI coding companion.
