Sidyma

A macOS utility for clearing the build artifacts your projects forgot.

Sweeps your project folders for build dirs, caches, DerivedData, simulators, and other transient artifacts, then lets you reclaim disk space without touching source code.

Sidyma running on macOS
Every clean leaves a record: what went to Trash, what a command removed, and what was skipped for being protected.

The name

Named after Sidyma.

Ancient city · Antalya & Lycia

Sidyma takes its name from Sidyma, an ancient Lycian city perched in the hills above today's Fethiye. A quiet vantage point that helped you see what to keep and what to let go — fitting for a tool that watches what builds up on your disk.

Roots matter.
