DevPrune: disk cleaner that only deletes rebuildable files

Cleans developer disks by removing only caches and artifacts that can be rebuilt

Problem

Dev machines fill up with node_modules, build caches, model weights, and temp artifacts, but generic cleaners risk deleting unrecoverable files, so users hesitate. Developers need a clear basis for deciding what can be regenerated.

Solution

Scan common dev artifact directories, identify rebuildable content, and show the rebuild cost (time, network, commands) so users can clean by category. Produce a cleanup report with rebuild commands and scheduled reminders.

Users

Engineers with many local projects, AI model experimenters, and laptop users short on disk

MVP

Scan common dirs like node_modules, build caches, and package caches; label rebuildable vs. not; clean by category and generate rebuild commands; history and space stats

Revenue

Free basic cleaning plus a one-time Pro license (scheduling, model weight detection, team rules); or annual team seats

Why now

Local model runs and multi-project work are straining disks, while big-brand cleaners don't judge 'developer rebuildable' content; a similar Show HN already validates demand
