Mac Disk Space Calculator for Developers
Estimate how much disk space your developer caches are wasting. Answer a few questions and see your estimated cache bloat.
Which developer tools do you use?
How Much Space Do Developer Caches Use on Mac?
On average, a macOS developer accumulates 15-50 GB of cache files within the first year of use. iOS developers using Xcode tend to see the highest numbers — DerivedData alone can grow to 20-50 GB on machines with multiple active projects.
Android developers using Gradle typically accumulate 5-15 GB in .gradle caches, plus additional space for AVD emulator images. Full-stack developers working with npm, Python, and Docker can easily have 10-30 GB of hidden caches.
Why Does "System Data" Keep Growing on Mac?
If you have noticed your Mac system data growing, developer caches are often the biggest contributor. macOS categorizes many of these caches under "System Data" in storage settings, making it hard to identify what is actually taking up space. SweepKit breaks down these caches by tool so you can see exactly where the space is going.
