DiskLens is a sleek disk space analyzer for macOS. Scan your drive, watch what's eating your space light up, and reclaim it — multi-select, search, sort, clean. All from a dark-themed web UI running locally on localhost:3847.
Finder shows you folders. DiskLens shows you where your space actually went. Scans live on your machine — no uploads, no accounts, no telemetry — and leaves deletion firmly in your hands.
Node walks the filesystem directly — no indexing daemons, no waiting for Spotlight. Scans start instantly and stream results as they're measured, so big folders show up the moment they're found.
List view with proportional bars. Grid view for quick scanning. Breadcrumb navigation, search, sort — the usual Finder-ish moves, but built for "what's big."
Select anything, delete in one click. By default items go to macOS Trash — fully recoverable via Finder. Permanent delete is a deliberate opt-in per action.
Delete is restricted to files under your home directory. System paths are protected at the server layer — not just hidden in the UI. You can't accidentally remove /System or /Library.
Arrow keys to navigate, / to search, ⌘D to delete, Enter to open. DiskLens is designed to be driven from the keyboard first — mouse if you want.
DiskLens is a small Node.js app — vanilla JS on the front, Express on the back. Read it top to bottom, fork it, ship PRs. Stats below are pulled live from the GitHub API when the page loads.

There are older free options and slick paid ones. DiskLens sits where those don't — a modern dark-themed UI, genuinely open source, keyboard-first, and safe by construction.
