Clean Next.js Build Cache on Mac
Last updated: 2026-06-05
Quick answer
Next.js stores build cache in .next inside each project. Delete with rm -rf .next or find across projects. node_modules is separate but often larger. CodeCleaner Project Scanner finds .next and node_modules ranked by size.

Next.js apps generate large .next folders with compiled pages, cache, and static assets. Combined with node_modules, a single app can exceed 1 GB — multiplied across many repos.
What is in .next?
.next contains compiled pages, webpack/turbopack cache, and static export output. It regenerates on next npm run build or next dev.
Find .next folders across projects
find ~/Projects -name .next -type d -prune -exec du -sh {} \; lists all instances with sizes. Limit scope to your code directory for speed.
How CodeCleaner finds Next.js artifacts
Project Build Artifact Scanner detects .next, node_modules, dist, and build folders with a whitelist of safe names. Scan first, review before deleting.
Manual steps (Terminal)
Run these commands in Terminal first. Scan first, review before deleting — or use CodeCleaner for a visual interface with per-item size breakdowns.
List .next folders with sizes
find ~/Projects -name .next -type d -prune -exec du -sh {} \;Remove all .next under Projects
find ~/Projects -name .next -type d -prune -exec rm -rf {} +Remove .next in current project
rm -rf .next # inside a single projectSafety warnings
- Run find list before bulk rm. Active projects will rebuild .next on next dev or build.
