Menu bar system monitoring
Shows live memory pressure, storage, and CPU details from the menu bar, with the monitoring view refreshed every few seconds. Monitoring remains free after the trial.
WTMemory
WTMemory is a lightweight macOS menu bar utility that monitors system resources and identifies storage used by local AI models, developer caches, app leftovers, and background processes. Free inspection remains available after the trial, while Pro adds cleanup and process-control actions.
Mac system, storage, and developer cleanup utility
WTMemory is a lightweight macOS menu bar utility for inspecting memory, CPU activity, and disk usage, with particular attention to the storage and background processes common on development machines. It helps users locate local AI model weights, build caches, app leftovers, and development servers instead of presenting only broad system-junk categories.
Monitoring and inspection are available free, including a seven-day full Pro trial on each installation. Pro adds cleanup, memory and storage reclaim actions, and process-killing tools. Cleanup is designed to be reviewable: Safe Mode moves selected items to the macOS Trash by default, while the utility states that documents, projects, and code are not modified.
Core features
Space Inspector
Scans local AI and LLM storage, developer and build artifacts, system caches and logs, and leftovers from deleted applications. Results can be reviewed before any cleanup.
Local AI model discovery
Targets forgotten local model data, including Ollama weights, Hugging Face downloads, LM Studio models, Cursor workspace data, and Claude Code caches.
Developer and cache cleanup
Provides cleanup actions for selected storage categories and developer artifacts, including Xcode DerivedData, package-manager caches, Bun, Cargo, Gradle, Docker, and simulator data. Safe Mode moves items to Trash by default.
Process cleanup
Offers one-click actions for runaway Vite, Next.js, nodemon, esbuild, Wrangler/workerd, and related development processes. It can also ask resource-heavy browsers, Electron apps, IDEs, and Docker to quit.
Quick system actions
Includes macOS-focused actions such as inactive-memory purge, purgeable-space reclaim through local snapshot thinning, Trash emptying, DNS-cache flushing, Finder restart, and a combined Deep Clean workflow.
Practical use cases
Recover space used by local AI tools
Run the Space Inspector to review large Ollama, Hugging Face, LM Studio, Cursor, or Claude Code directories before deciding what to remove. This is useful when local models and related caches have accumulated outside the folders users normally check.
Audit a development machine
Inspect Xcode DerivedData, simulator runtimes, Docker virtual disks, and npm, pnpm, Yarn, Bun, Cargo, or Gradle caches when a development Mac’s storage is unexpectedly full.
Stop orphaned development processes
Use the process controls when a Vite, Next.js, nodemon, esbuild, Wrangler/workerd, or Python development process remains active after a project is closed or continues holding a port.
Troubleshoot sluggish performance
Open the menu bar monitor when the Mac feels slow or fans are active, then review memory pressure and CPU usage before using an available purge or quit action.
Choose a focused cleaner
Use the app as a simpler alternative to a broad consumer cleaning suite when the priority is offline inspection and developer-oriented storage cleanup rather than malware, browser, or photo management.
Pros and Cons
Pros
- Free monitoring and Space Inspector access continue after the Pro trial.
- Purpose-built inspection covers local AI model data and developer build artifacts.
- Safe Mode moves cleaned items to Trash by default, providing a reversible workflow.
- The app is a small 794 KB universal binary for Apple Silicon and Intel Macs and states that it operates offline without analytics or telemetry.
Cons
- It is a macOS-specific utility rather than a cross-platform cleaner.
- The product does not include malware scanning, browser privacy cleanup, or photo-duplicate detection.
- Some cleanup and process-control actions require Pro after the seven-day trial.
FAQ
How does the free tier work?
WTMemory is a Mac menu bar utility. Install it and it begins with a seven-day full Pro trial; no email address or account is required. After the trial, monitoring and inspection remain available for free.
What can WTMemory inspect?
The Space Inspector scans AI and LLM storage, developer and build artifacts, system caches and logs, and leftovers from apps that have been deleted. Scanning and reviewing results are free; cleaning selected items requires Pro.
What happens when WTMemory cleans files?
By default, cleanup moves selected items to the macOS Trash, making the action reversible. You can turn off Safe Mode for permanent deletion. WTMemory states that it does not modify documents, projects, or code.
Can WTMemory help find local AI and developer storage?
The utility can identify local Ollama weights, Hugging Face downloads, LM Studio models, Cursor workspace data, and Claude Code caches, as well as caches and artifacts associated with tools such as Xcode, package managers, Bun, Cargo, and Docker.
Who is WTMemory best suited for?
WTMemory is designed for macOS users who want menu bar monitoring, storage inspection, and cleanup of developer or local-AI artifacts. It does not include malware scanning, browser privacy cleanup, or photo-duplicate detection, so it is not a full consumer security and media-management suite.
