ImageFlow

ImageFlow is an open-source image editor built specifically for macOS, positioned around a node-based editing model rather than conventional layers. It targets users who want to build image adjustments and designs as connected graphs, where each step remains visible and adjustable. The app requires macOS 26 Tahoe or newer and is sold as a one-time purchase with all features included.

The core of the product is its node graph: effects, images, and even mathematical operations can be wired together without the constraints of layer-based workflows. Every node previews in real time through GPU acceleration, and previews can be floating, docked, or opened in as many windows as needed. The node library exceeds 200 entries, covering blur, color adjustments, visual effects, filters, stylization, color quantization, tiling, procedural generation, math, and general programming nodes.

Because it is native to macOS, ImageFlow integrates with Photos and the standard document workflow, including auto-saving, document restoration, and undo/redo. This makes it a fit for photographers refining images and designers building generative or procedural visuals who prefer a Mac-native environment over cross-platform editors.

New users should expect a learning period: thinking in graphs is different from stacking layers, so starting with a few nodes and inspecting previews at each stage helps. The open-source nature and one-time pricing lower the commitment, while the growing node library rewards
