Open Source Adobe Photoshop Alternatives

Graphite is a free, open source vector and procedural graphics editor that runs entirely in your browser without requiring an account or installation. It's aimed at designers who want a nondestructive workflow, where every creative decision stays editable through parameters rather than being baked in permanently.

Unlike most online design tools, Graphite is built around a node graph at its core. Instead of drawing shapes and committing to them, you build systems of nodes that generate and transform artwork procedurally. Want your scattered circles denser? Drag a slider. Want a different fill pattern? Swap a node. Nothing is destructive by default.

Key capabilities include:

• Procedural vector editing using a node-based layer system that lets you compose, reuse, and automate design workflows
• Nondestructive boolean operations for combining and modifying shapes without losing the originals
• Parametric iteration so you can morph between states, blend color schemes, or adjust placement areas with sliders rather than manual edits
• Infinite scalability with no pixelation, and export to SVG, PNG, or JPG at any resolution
• Fully local execution with no server involved, keeping your work private on your own hardware

Graphite is built with WebAssembly and WebGPU, which gives it performance closer to a native app than a typical browser tool. It's architecturally more like a game engine than a conventional creative app.

Desktop apps for Windows, Mac, and Linux are in late development, but the browser version is already functional and kept current. The project is in alpha, so some planned features like raster editing, live collaboration, and standalone program compilation from node graphs aren't available yet.

For designers tired of jumping between a vector editor, a compositing tool, and a generative design environment, Graphite is building toward a single app that handles all of it. It's a credible open source alternative to tools like Penpot for those who want procedural depth over a traditional layer-based approach.

Compositor is a free, open-source image editor for Mac, built specifically around compositing and post-processing. It targets photographers and designers who find Adobe Photoshop too expensive but feel that tools like GIMP break their workflow. The interface and toolset are designed to feel familiar to Photoshop users without the subscription cost.

The core focus is pixel-perfect compositing. That means the feature set isn't spread thin across illustration or vector work; it's concentrated on what you actually need to combine, retouch, and finalize images.

Key capabilities include:

• Layers and folders for organizing complex compositions
• Layer masks and clipping masks for non-destructive editing
• Blend modes to control how layers interact
• Selection tools for isolating subjects and regions
• Adjustment layers for color and tone corrections
• Background removal built directly into the app
• Filters including Gaussian blur, motion blur, and lens correction
• Grain and noise for adding film-like texture
• Liquify and smear for warping and reshaping
• Spot healing and clone stamp for retouching
• Brush tool for painting and touch-ups

Because the full Xcode project is available, you can add, remove, or modify any feature to suit your needs. That's a meaningful difference from other photo and video editors in this space: the source is genuinely open and buildable, not just visible. Mac-only by design, so it takes full advantage of the platform rather than trying to be cross-platform everywhere.
