    VectorCraft

    VectorCraft

    An open-source, clean-room reimplementation of Adobe Illustrator

    ...It provides tools such as Pen, Direct Selection, Pathfinder, Smart Guides, layers, swatches, blends, gradient meshes, repeats, and envelope distortion. Exact curve booleans and structural-sharing undo are designed for reliable editing. Its native format is JSON-based, while SVG, PDF-compatible AI, PNG, JPEG, WebP, and other formats are supported for interchange. The same codebase runs on macOS, Windows, Linux, FreeBSD, and WebAssembly. A JSON control channel and MCP server expose editing commands to AI agents for automated drawing and export workflows.

    Graphite

    Graphite

    An open source graphics editor for 2025

    ...It combines traditional vector drawing capabilities with features like animation timelines, state machines, and interactive prototyping—all in one toolchain rather than separate apps. The interface supports layering, boolean operations, masks, and full node-based parametric controls for shapes and effects. Because it’s built to be extendable, plugin support allows importing/exporting formats, custom tools, or integrations with code frameworks. It also focuses on performance and scalability—handling complex vector scenes with many nested elements fluidly. For designers and developers looking to prototype UI transitions, interactive states, and motion-driven interfaces without separate design/code handoffs, Graphite positions itself as an all-in-one creative engine.
