Full cross-platform rewrite of CSP-Analyzer: .NET 8 + Avalonia UI (Linux/Windows/macOS), replacing the original WinForms/.NET Framework 4.5.2 + IronPython 2.7 stack. Modern Python backend (Python 3.12, current numpy/scipy/scikit-learn/scikit-image), safe (non-pickle) model persistence, and a self-contained packaged build with no separate Python/conda install required — the classifier backend is bundled directly into the app via PyInstaller. Downloads Pick the zip for your OS, extract it anywhere, and run the executable directly from the extracted folder (CspAnalyzer.Desktop.exe on Windows, ./CspAnalyzer.Desktop on Linux/macOS). See the README's Installation section for details. Highlights since v1.0 Full UI port from WinForms to Avalonia (cross-platform) Python backend modernized to a clean, tested package (Python 3.12) Safe model artifact format (no runtime pickle loading) Self-contained per-OS packages, no bundled Miniconda/manual setup Relicensed from GPL-3.0 to MIT; see THIRD_PARTY_LICENSES.md for bundled dependency licenses GitHub Actions CI across all 3 OSes License MIT (previously GPL-3.0 — see THIRD_PARTY_LICENSES.md for third-party component licenses).
