About CleanDev
Last updated: 30 October 2026
Who makes CleanDev
I’m Ahmet Karaca, a solo developer working under Akaya Labs. I build, test and support CleanDev myself. You can see my other Mac and iOS apps on my App Store page.
Why it exists
On 20 September 2026 my 460 GB Mac was down to 503 MB free, and macOS called almost all of it System Data. Cleaning it by hand got the free space back up to 148 GB. Apart from old apps, what came back had been left by developer tools. General-purpose cleaners found little of it, so I built one that knows these tools.
How the guides are written
Paths and sizes in the guides come from my own Mac, with the month of measurement. Commands are checked against each tool’s help output and documentation. Commands that delete something get their own block, so you can read them before you run them.
