14 side-by-side comparisons. Four weighted criteria each, every rating cited, and an explicit note on when not to use it. You set the weights.
Each comparison scores two tools on four weighted criteria. Every rating links to its source. And every one states when not to use it — because most bad choices come from ignoring the downside, not from missing the upside.
Cursor or Claude Code? Supabase or Neon? Each comparison is a real fork in the road.
Four criteria, each with a rating and a source. Anti-personas tell you who should walk away.
Drag the sliders. The recommendation recalculates against your constraints, not a generic average.
Choose Cursor for IDE-first speculative inline edits; choose Claude Code for autonomous terminal execution and deep codebase refactoring.
Both ship a usable free tier. For one flat paid subscription that includes frontier-model quota, choose Devin Desktop (the product formerly shipped as Windsurf, now under Cognition). For a cheap Grok-only start, or a mid-tier plan that unlocks multiple models together with cloud agents, choose Cursor.
Choose Bun for a measurably faster cold start (see the metric below, sourced to our own harness) and built-in SQLite/bundler; choose Node 22 for a documented LTS lifecycle and legacy native addons.
Choose Supabase for all-in-one Auth, Storage, and Realtime primitives; choose Neon for instant database branching, zero-load scale-to-zero, and autoscaling compute.
