Mac app for people who build
Your Mac isn't slow. It's full.
cleno finds the gigabytes hiding in Xcode, node_modules, Docker, simulators and caches, shows you exactly what they are, and clears them in one click. So you can get back to shipping.

What it clears
Xcode DerivedData
Build caches that Xcode regenerates on the next build. Often the single biggest thing on a Mac.
Simulator runtimes
Old iOS, watchOS and tvOS versions you're not testing against anymore.
node_modules
Dependencies in projects you haven't touched in 90+ days. One npm install brings them back.
Docker images & volumes
Unused images, stopped containers and dangling volumes that quietly pile up.
Package caches
Homebrew, npm, pip, Yarn and pnpm download caches. Safe to clear, always rebuilt.
Large downloads
Installers, DMGs and archives you already opened and forgot about.
How it works
- 1
Scan
30 seconds, read-only. cleno looks, it doesn't touch.
- 2
Review
Every item explained in plain English. Nothing pre-hidden.
- 3
Clean
One click. Only what you checked, nothing else.
Nothing gets deleted without you
Read-only scan. cleno touches nothing until you click Clean.
Every item explained in plain English before you decide.
Never touches your projects, documents, photos, or anything it can't explain.
Stop deleting screenshots to make room for a build.

Questions
Will this break my projects?
No. It only clears regenerable caches and dependencies in projects idle for 90+ days, and shows you each one first.
Is it safe?
Read-only scan, explicit review, one-click clean of only what you checked. Nothing goes to Trash silently.
How is this different from CleanMyMac?
Those are general cleaners. cleno understands developer tooling — DerivedData, simulators, node_modules, Docker — that they skip or mishandle.
What does it cost?
Free for early users. Pricing later, early users keep access.
