WTMemory
WTMemory is a native macOS menu bar utility developed by STAGSTER Labs LLP. It monitors live unified RAM pressure caused by applications, IDEs, and background processes, and provides tools to reclaim memory and storage. The app is distributed as a 794 KB universal binary for Apple Silicon and Intel Macs, and it operates entirely offline with no tracking or cloud connections. The tool focuses on modern development environments, identifying and cleaning caches and artifacts that accumulate on developer machines. It can find local AI model weights from Ollama, Hugging Face, LM Studio, and ComfyUI, as well as developer junk such as Xcode DerivedData, Docker images, npm/pnpm caches, and unavailable iOS Simulator runtimes. It also provides one-click termination of orphaned dev servers (e.g., Vite, Next.js, Python) and heavy apps. WTMemory offers a free inspection mode that scans and reports memory and storage usage. The Pro version, available as a one-time $9 purchase (lifetime, up to 3 Macs), unlocks one-click cleaning, direct memory purge, and deeper cleanup actions. The app is built with Swift 6 and invokes kernel purge routines directly, avoiding Electron bloat.

Problem solved
Modern development environments accumulate invisible performance drains: cached machine learning models, orphaned Docker containers, npm package caches, and zombie dev servers consume significant RAM and disk space, slowing down Macs. Traditional cleaners do not recognize these developer-specific artifacts, leaving users to manually hunt and delete them. WTMemory addresses this by identifying and cleaning these hidden resource hogs.
Use cases
- Free up RAM by purging inactive memory and killing heavy background processes on a Mac
- Discover and delete local AI model weights from Ollama, Hugging Face, LM Studio, and ComfyUI to reclaim disk space
- Kill orphaned development servers that hold ports like 3000, 5173, and 8080
- Clean Xcode DerivedData, Docker dangling images, npm/pnpm caches, and iOS Simulator runtimes
- Monitor real-time unified memory pressure and storage usage from the menu bar
- Clear DNS cache and restart Finder to resolve network or UI glitches
Audience
- Developers
- ML Engineers
- Data Scientists
- Hobbyists
- Business Users
Pros
- Free inspection mode with no cost to see what's consuming resources
- One-time $9 lifetime license for up to 3 Macs, no subscription
- Extremely small 794 KB native Swift binary, offline and privacy-focused
- Specialized detection of AI model caches and developer-specific junk
- One-click termination of orphaned dev servers and heavy processes
Cons
- Only available for macOS; no Windows or Linux support
- Cleaning features require a paid Pro license after trial
- Limited to Mac-specific cleanup targets; not a general system optimizer
- No GitHub repository or public issue tracker for community feedback
- May not appeal to users who prefer open-source or auditable software
