InkForge

What InkForge is

InkForge is a free, open-source raster drawing app for Windows, macOS, and Linux. Its GPU-backed canvas uses a stamp-based brush engine with six procedural texture tips; pen pressure can control brush size and opacity. Artists can use unlimited layers, twelve blend modes, clipping masks, and non-destructive layer effects. The frame-by-frame timeline supports duplication, onion-skinning, adjustable FPS, and GIF or WebM export. Native .inkforge projects preserve layers and frames, while export formats include PNG, JPEG, and TIFF. An AI panel lists fourteen modes, including style transfer, sketch-to-painting, inpainting, and background removal. Generation can use Gemini or Replicate with the user's own key, or a local ComfyUI graph. The maker says keys are stored locally and the ComfyUI path stays on the machine. The maker describes the MIT-licensed app as under active development on its cross-platform build and identifies the native macOS version as its original Swift implementation. The download section lists Windows 10+ and macOS 13+ requirements.
