A high-performance, open-source Win32 desktop utility engineered by Prakhar Yadav (@blazecodeprakhar). Reclaim gigabytes from heavy developer build caches, flush GPU shader pipelines, and trim RAM working sets with zero telemetry.
EmptyWorkingSet RAM Trimming
Single file portable executable (.exe)
Technical breakdown of supported Windows operating systems, Win32 APIs, developer toolchains, and engine architecture.
| Engine Dimension | Technical Details & Compatibility |
|---|---|
| Supported OS | Windows 10, Windows 11, Windows Server 2019+ (64-bit Architecture) |
| RAM Optimization | Win32 EmptyWorkingSet process memory trimming via native psapi.dll API calls |
| GPU Shader Caches | NVIDIA (DXCache, GLCache), AMD Radeon (DxCache, OglCache), DirectX (D3DSCache), Intel Arc Graphics |
| Developer Toolchains | Node.js (NPM, Yarn, PNPM), Python (Pip, Poetry, UV), Java (Gradle, Maven), Rust (Cargo), Go (go-build) |
| App Leftovers & Audit | Scans AppData directories and cross-references with installed apps in Windows Registry |
| UI Framework & Binary | CustomTkinter Python GUI | Standalone Single-File Windows Executable (Cachey.exe) |
| License & Author | MIT License | Built by Prakhar Yadav (@blazecodeprakhar) |
Automated multi-threaded scanning for developer build caches, system RAM working sets, and obsolete app leftovers.
Trims unused process RAM working sets and purges compiled GPU shader caches to eliminate gaming stutter.
EmptyWorkingSet system callsScans and clears accumulated dependency stores from software development environment toolchains.
Identifies orphaned application folders and auto-generated temporary script files safely.
Follow these 3 simple principles to reclaim maximum disk storage without touching personal files.
To scan and clean a specific disk drive or external volume (e.g. D:, E:, or external SSD), simply place the Cachey.exe file inside that directory. The executable runs portably and focuses scan operations on that drive!
For routine maintenance, use the Recommended & Safe preset. This preset targets non-essential build caches and temp files while protecting personal documents and project files.
Review detected target items before executing a complete purge. You can easily toggle individual target checkboxes to clean only the exact directories you choose.
Cachey by Prakhar Yadav (@blazecodeprakhar) is 100% open source, certified by SignPath Foundation, and runs strictly offline.
Every single line of code is published on GitHub under the permissive MIT License. Inspect every detector module, Win32 API call, and build script.
Inspect Source on GitHubCode signing for release builds is managed via GitHub Actions and authenticated by the SignPath Foundation for verified binary safety.
Verify SignPath ProgramRuns strictly on your machine. Cachey contains zero ads, zero analytics tracking, and makes zero background network connections.
100% Privacy FirstTrims process memory using standard Win32 EmptyWorkingSet calls. No kernel drivers, background services, or risky registry tweaks.
Verify your downloaded executable binary is authentic by running this PowerShell command on your PC:
Get-FileHash Cachey.exe -Algorithm SHA256
Terminal commands to clone, run, and compile Cachey locally using Python 3.10+.
