About Lazpaint

LazPaint is an open-source image editor for Windows, macOS, and Linux. It supports raster and vector layers and is written in Lazarus (Free Pascal) using the BGRABitmap library. The project describes itself as similar to Paint.NET and PaintBrush. It offers layered drawing tools, selection tools, color adjustments, and filters, and it can read and write several file formats, including layered bitmaps and 3D files.

The source is the project's GitHub repository page and README. It states that LazPaint can be made portable and is available in some Linux repositories. It does not describe pricing or a plan structure, so known pricing is unknown. The project also accepts donations for development.
