A look inside

This is how Spaci looks.

Smart scan, storage breakdown, recommendations and one-click cleanup, in one calm window.

Disk breakdown

See exactly where your disk went.

One scan classifies your whole drive into coding, media, apps, documents and system, so the space worth reclaiming stops hiding inside a vague "Other".

Macintosh HD 328 GB used of 512 GB
Coding 86 GB node_modules, build, caches
Media 74 GB photos, video, audio
Apps 58 GB installed applications
Documents 46 GB files and downloads
System 64 GB macOS and data
Free 184 GB available space
Why Spaci

Built to clean the stuff IDEs leave behind.

One-click cleanup

Pick what to remove and Spaci clears node_modules, build output and caches in seconds. No terminal, no rm -rf.

Smart detection

Spaci recognises project types across your machine automatically, so it knows what is safe to clear and what to leave alone.

Safe by design

Every action previews first, and reversible cleanups stay separate from permanent deletes. You stay in control.

How it works

Three steps from cluttered to clean.

01

Scan

One smart scan sweeps your projects and system caches, sizing everything in the background.

02

Review

Recommendations rank what is worth clearing, with a preview of every folder before it goes.

03

Reclaim

Clean in one click. Reversible actions undo from history; permanent ones are clearly flagged.

What's new

Full changelog
v2.1.0 August 17, 2026 Latest

Spaci now sees Docker, and scans your projects about ten times faster.

  • Docker: Spaci measures the images, containers, volumes and build cache the engine is holding, which a normal disk scan cannot see because it all lives inside one VM disk.
  • Projects that use Docker are marked in the list, and their project page shows the compose services and the engine storage that actually belongs to them.
  • Reclaim Docker build cache and unused images from the System screen or straight from Recommendations. Volumes are never touched: they hold your databases and uploads.
