● EDITORIAL VERDICT · BIGBANGINDEX

Windsurf edges GitHub Copilot on aggregate — 78 vs 77.

The best free alternative to Cursor - Cascade mode genuinely feels like pair programming with a senior dev. GitHub Copilot still wins for buyers who prioritise deep github integration with pr summaries, issue triage, and code review. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
