GitHub (Copilot) vs Windsurf

Both products compete in AI Code Generation. AI code generation software uses large language models to write, complete, refactor, and explain code as developers work. It ranges from inline autocomplete inside an editor to agentic tools that can plan, write, and run multi-file changes on their own. Here are the facts the B4 Index maintains on each, side by side.
