Turborepo Has a Free Monorepo Build System That Never Rebuilds Twice

Your monorepo CI takes 45 minutes because it rebuilds everything. Turborepo caches build outputs and only rebuilds what changed — cutting CI time by 40-80%. The Problem monorepo/ apps/web/ ← Changed 1 file apps/api/ ← Unchanged packages/ui/ ← Unchanged packages/config/ ← Unchanged Traditional CI: Rebuild ALL 4 packages. Time: 15 minutes. Turborepo: Rebuild ONLY web (cache the rest). Time: 3 minutes.
