Show HN: Klad, a paint app your coding agent can drive (source-available)

Klad is a source-available 2D painting and animation app that allows human artists and coding agents to collaborate on the same drawing in real-time, with both using the same brushes and seeing each other's strokes instantly. Unlike image generators, Klad preserves every stroke and fill as editable data rather than pixels, enabling precise adjustments to individual elements without regenerating the entire image. The app is currently available for macOS with pen pressure support and can be built on Linux and Windows.
