Komac is an advanced CLI designed to create manifests for the WinGet Community Repository.

Komac is both blazingly fast 🔥 and incredibly low on memory, using just ~3.5MB of memory on my machine.



Komac is cross-platform and binaries are built for Windows, Linux, macOS, and FreeBSD.

All platforms

If you have cargo installed, you can compile Rust for any platform

cargo install komac

Komac also supports cargo-binstall:

cargo binstall komac


Both portable EXEs and installers are available from the releases.


winget install komac


scoop install komac


Portable binaries are available from the releases. Debian (.deb) and Red Hat (.rpm) installers are also available.


Portable binaries for macOS are available from the releases.


brew install russellbanks/tap/komac

GitHub Token

Komac is currently only able to use a classic token. Whilst Komac can fully create manifests and commit with a fine-grained token, it fails to create a pull request to winget-pkgs. This may change as fine-grained tokens improve. See https://github.com/russellbanks/Komac/issues/310.


A classic token with the public_repo scope.

Komac vs other tools 🏆

While other manifest creation tools have made remarkable strides in the winget-pkgs community, their development pace is notably slow and lacks the advanced detection capabilities that come with Komac.

[^1]: If all installers have the same value, that value is put at the root of the manifest to reduce redundancy. [^2]: Telemetry is enabled by default in WingetCreate. Use wingetcreate settings to manually disable telemetry. [^3]: There is much more accurate detection for Inno, Nullsoft, and Burn installers since Komac v2. [^4]: The logic for this was contributed by me :) Check issues that I've opened to request this feature for YamlCreate.

Usage with GitHub Actions: WinGet Releaser 🌟

WinGet Releaser is a GitHub Action that invokes Komac, passing in your release's URLs. This completely automates publishing to WinGet.

Example 📝

name: Publish to WinGet
    types: [ released ]
    runs-on: windows-latest
      - uses: vedantmgoyal2009/winget-releaser@v2
          identifier: Package.Identifier
          token: ${{ secrets.WINGET_TOKEN }}
          # installers-regex: '\.exe$' # Only .exe files
