MoreRoom vs DevCleaner for Xcode

DevCleaner for Xcode is a focused, free tool for one job: clearing the caches Xcode builds up in ~/Library/Developer. It is open source and includes a command line tool you can drop into scripts. MoreRoom covers the same Xcode folders as part of a wider storage manager that also handles simulators, other developer tools, local AI models and System Data. If Xcode is your only problem, DevCleaner for Xcode is a sensible first choice.

What each app is

DevCleaner for Xcode, by Konrad Kołakowski (One Minute Games), lets you inspect Xcode’s auto-generated files and clean them. Its GitHub README lists Device Support, Archives, Derived Data, Documentation Cache, Old Simulator and Device Logs, and Old Documentation Downloads. As of October 2026, the Mac App Store lists version 2.8.0 (November 2025), free with optional tips, requiring macOS 14 or later. It includes a command line tool, which since version 2.6.0 can run in headless environments such as SSH sessions or CI. The source is GPL-3.0.

MoreRoom, by Yando Pte. Ltd., is a native macOS storage manager for macOS 15 Sequoia or later. Among its 249 rules are Xcode’s DerivedData, Archives, Device Support for each platform, SwiftUI previews, test and playground simulators, Xcode caches, simulator devices, simulator runtimes and other installed Xcode versions. It also shows your whole disk as a treemap, rings or list.

Where DevCleaner for Xcode is better

• Free and open source. You can read the code, and the app costs nothing. Tips are optional.
• Command line tool. You can run cleanups from scripts, over SSH or in CI. MoreRoom’s command line is coming soon but not available yet.
• Xcode-specific details. It cleans documentation caches and old documentation downloads, and its Archives view shows whether an archive was submitted for review or notarized — useful context before deleting one.
• Focus. Everything in the app is about Xcode, so there is little to learn.
• Mac App Store distribution. Updates come through the App Store. MoreRoom is not on the Mac App Store yet.
• macOS 14 support. It runs on macOS 14 Sonoma; MoreRoom needs macOS 15 Sequoia.

Where MoreRoom is better

• Simulators and runtimes, removed the official way. Simulator devices and runtimes are often the largest Xcode-related items. MoreRoom removes them with Xcode’s own commands — xcrun simctl delete for a simulator and xcrun simctl runtime delete for a runtime — and labels those steps as permanent, because they are. Our guide Xcode DerivedData, simulators and Device Support explains each folder.
• Beyond Xcode. Developers rarely only use Xcode. MoreRoom also recognises Docker data, Homebrew downloads and old versions, npm, pnpm, uv, conda and Go caches, Rust toolchains, Android emulators and SDK packages, Node version managers and local AI models. Where a tool has an official cleanup command, MoreRoom uses it.
• Trash first, with Undo. Ordinary folders go to the Trash first, and you can undo.
• Safety badges. Each item is marked “Safe to remove” or “Review first”, with whether it comes back. Archives, for instance, are not treated as caches, because you need them to read crash reports from the builds you shipped.
• The whole disk. A System Data breakdown, Storage Weather (30-day history and forecast), Ghost space and Keep in the Cloud help with space that is not developer-related.
• Project hibernation (Pro). Inactive projects can drop rebuildable folders such as node_modules, build folders or Unity’s Library, and wake again in one click. Pro also finds old tool versions.

Which should you choose?

Choose DevCleaner for Xcode if…

• Xcode caches are the main thing filling your disk;
• you want a free, open-source tool;
• you want to automate cleanup from scripts or CI today.

Choose MoreRoom if…

• simulators, runtimes and other developer tools also take space;
• you want each item explained with a safety badge before removing it;
• you want a view of the whole disk, including System Data.

Without any app

You can clear DerivedData yourself by quitting Xcode and moving ~/Library/Developer/Xcode/DerivedData to the Trash, and list unavailable simulators with xcrun simctl list devices unavailable. The guide linked above covers what each command does and whether it can be undone. For JavaScript projects, see Cleaning up node_modules.
