SlimWin is a disk-cleanup CLI tool for Windows developers. The main page currently lists it as v1.1.0, free, and including all features. It is not a general-purpose cleaner; instead, it targets the common sources of bloat on development machines: package manager caches, build artifacts, Docker/WSL, IDE caches, system temporary files, and preinstalled apps. Installation is via dotnet tool install -g SlimWin, and it requires Windows 10/11 and .NET 8+.
In terms of coverage, SlimWin supports 60+ developer caches, including npm, NuGet, pip, Cargo, Go, Maven, Gradle, and Composer. It also covers build and framework artifacts such as node_modules, venv, .next, Bazel, and coverage folders. For Docker, it can handle unused images, stopped containers, orphaned volumes, build cache, and logs; for WSL, it supports compressing ext4.vhdx. It also detects IDE caches from Visual Studio, VS Code, Cursor, JetBrains, Vim/Neovim, and others, and can remove some Windows preinstalled apps and vendor software.
The tool provides a four-level safety system: Safe is selected automatically; Caution and Review require user judgment; Dangerous is never selected automatically and requires explicit confirmation. This is important for cleaning development environments, since accidentally deleting global tools, WSL distributions, or local dependencies can disrupt workflows. CLI commands include an interactive wizard, --scan, --report, license activation, and version lookup. Reports can be exported as TXT, CSV, or JSON, making the tool usable for CI/CD or scripted disk-usage audits.
Pricing is very straightforward: it is free, requires no credit card, includes all cleanup categories and export formats, and supports unlimited activations. However, users must obtain a license key via email, and the tool performs periodic online validation. The terms also state that anonymous usage telemetry is collected, and requesting a key means agreeing to receive marketing emails. The tool supports Windows only, not macOS/Linux. The main page also does not provide information about a graphical interface, enterprise support SLA, or a full API/SDK.
SlimWin is best suited to developers who primarily work on Windows, especially multi-stack users of Docker/WSL, Node, .NET, Python, Java, Rust, and similar ecosystems, as well as teams that need to generate disk-usage reports regularly. Access from China is not described on the main page; NuGet installation and license validation may be affected by poor network conditions. If access is limited, alternatives include Windowsβ built-in Disk Cleanup, Storage Sense, BleachBit, WinDirStat/WizTree, or the cleanup commands built into Docker and individual package managers.
