FireAlpaca vs InkForge

FireAlpaca is a digital painting program for making illustrations and images, available on Windows, macOS, and Linux. Its listed tools include animation, mesh deformation, gradient maps, lasso fill, CMYK display, text, halftone, 3D perspective, tone curves, and reference windows. The standard software supports 10 languages, and the maker distributes original brushes weekly in styles including pencil, watercolor, motifs, patterns, and effects. Brush customization, layers, pressure sensitivity, and stroke stabilization are supported; color management is described as basic. The free edition permits individual and commercial use without a license fee. Its separate FireAlpaca SE edition adds onion-skin animation with GIF or APNG export, a store with more than 300 brush types, a liquify tool, and layer masks. SE costs 39.99 USD once. Listed downloads are version 2.16.3 or later requirements: Windows 10 or later, macOS 12 or later, and Linux distributions including Ubuntu 23.04, Fedora 36, and Debian 12 or later.

InkForge is a GPU-backed raster drawing app with a stamp-based brush engine, layers, selection tools, animation and an AI panel. Its six procedural texture tips support pressure control of brush size and opacity. The app offers unlimited layers, twelve blend modes, clipping masks and non-destructive layer effects. Its frame-by-frame timeline supports duplication, onion-skinning and adjustable FPS, with GIF or WebM export. Native .inkforge projects preserve layers and frames; export formats include PNG, JPEG and TIFF. The 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. InkForge is free and open source under the MIT license. It lists Windows, macOS and Linux support, while download requirements specify Windows 10+ and macOS 13+. The maker describes cross-platform development as active and the native macOS build as the original Swift implementation.
