PKHeX Avalonia is the cross-platform PKHeX port built with the Avalonia UI framework, bringing the classic Pokémon save editor to Windows, macOS, and Linux with a native look and feel.

Grab the latest release for your platform from the Releases page:

All releases are self-contained — no .NET runtime installation required.

macOS Note: The app is ad-hoc signed but not notarized, so on first launch macOS will warn "unidentified developer". To open it:

1. Right-click the app → select Open → click Open in the dialog
2. Or in Terminal: xattr -d com.apple.quarantine ~/Downloads/PKHeX.Avalonia.app

• PKHeX.Avalonia: The main application (cross-platform).
• Legacy/PKHeX.WinForms: The original Windows Forms application, kept as a reference archive.
• PKHeX.Core: Shared logic library (synced from upstream PKHeX).

• Save Editing: Core series save files (.sav, .dsv, .dat, .gci, .bin).
• Entity Files: Import and export .pk*, .ck3, .xk3, .pb7, and more.
• Mystery Gifts: Support for .pgt, .pcd, .pgf, and .wc* files.
• Transferring: Move Pokémon between generations while converting formats automatically.

• .NET 10 SDK

dotnet run --project PKHeX.Avalonia

dotnet build PKHeX.sln -c Release

dotnet test PKHeX.sln

dotnet publish PKHeX.Avalonia -c Release -r osx-arm64 --self-contained -p:PublishSingleFile=true

PKHeX Avalonia uses semantic versioning (1.0.0, 1.1.0, etc.) for the UI application. PKHeX.Core follows the upstream date-based versioning scheme.

To create a release, bump the <UIVersion> value in Directory.Build.props and push to main. The release workflow detects the new version, creates the git tag, builds all 4 platforms, and publishes a GitHub release — no manual tagging required.

Work in progress — the UI is changing fast.

This fork is built on the incredible work of the PKHeX team.
