What the current evidence supports

Human editorial judgment · 2026-08-20

Adopt with guardrails

Why
It is the vendor default and stable for build, with 2-5x build / up to 10x Fast Refresh claims and >50% dev-session adoption pre-default, but webpack-plugin dependence, opt-in build cache, and documented behavior diffs mean migration needs verification rather than a blind flip.
Next
On non-webpack-plugin apps, run next build with Turbopack on a branch, delete .next for a fair cold-build comparison (or enable turbopackFileSystemCacheForBuild), and validate CSS-module ordering + Sass imports + non-mainstream OS targets before merging.
