● EDITORIAL VERDICT · BIGBANGINDEX

Windsurf edges Amazon Q Developer on aggregate — 78 vs 74.

The best free alternative to Cursor - Cascade mode genuinely feels like pair programming with a senior dev. Amazon Q Developer still wins for buyers who prioritise unmatched aws service knowledge across lambda, dynamodb, ecs, etc.. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
