VectorCraft for Windows: Free Illustrator Alternative Tested Against Inkscape

What VectorCraft is​

ArtCraft is a project led by Brandon Thomas. It is a suite of sixteen free, open-source apps, the original seven of which stand in for Photoshop, Illustrator, Premiere, Lightroom, After Effects, InDesign and Acrobat. VectorCraft is the Illustrator entry. It is billed as a clean-room reimplementation, meaning it copies Illustrator's look and behavior but uses none of Adobe's code. The code is free and open source under MIT or Apache-2.0.

The AI angle is about how it was built, not what it does. Jonker reports that Thomas built the apps with Anthropic's Claude Opus 5.5 and that Claude is credited as co-author on most commits. A separate write-up by GreenNode says about 77% of the suite's commits list Claude Opus 5.5 as a co-author. That is a secondary source, so treat the exact percentage as approximate.

What Jonker found in use​

Jonker built a 1920x1080 YouTube banner. His observations:

• Layout: The Properties and Layers panels sit where Illustrator puts them. The shape tools have the usual flyout with spiral, arc and grid.
• Drawing tools: Smart Guides, Pen, Curvature, Pathfinder and Shape Builder all behave as an Illustrator user would expect.
• Selection: Select > Same > Fill Color let him recolor every matching object in one pass.
• Effects: Glows and drop shadows stay editable after you apply them. Warp gives a live preview as you drag its bend slider.
• Weak spot: The raster filters are approximations. The Effect Gallery has no thumbnails or preview yet, and a couple of Color Effects options were greyed out for him.

These are one reviewer's observations on one project, not a systematic test.

Performance claims​

The project's README says 20,000 shapes render in about 27 ms at full retina resolution while the interface stays at 120 fps. These are the developers' own numbers. Jonker adds that his frame counter never dropped below 115 fps, even zoomed past 11,000%. He also says Inkscape feels sluggish with as many layers as his test file had. That is his experience, not a benchmark, and performance on your own hardware and files may differ.

How finished is it?​

Readiness figures vary by source and by metric:

• Jonker says the team puts it at about 65% ready for a typical illustrator.
• The README snapshot dated 7 October 2026 says roughly 69–75% of Illustrator's features exist and work. It puts the "a power user can't tell the difference" measure at about 40–55%.
• A third-party guide says the roadmap estimates 65% for a typical illustrator and 62% against all of Illustrator.

These are self-assessments, so read them as direction of travel, not measurement. The same README lists what is still missing: 3D and Materials, the Photoshop-style raster Effect Gallery, Variables and scripting, and an interaction-fidelity pass over every tool's modifiers. Vertical type has only initial support. It also lists packaging for Windows and Linux as unfinished. The stated path is interaction fidelity and raster effects first, then 3D and advanced type, then hardening and packaging for 1.0.

File compatibility​

This is the biggest decision point for anyone who trades files with Adobe users.

• Opens: SVG, PDF, PDF-compatible .ai, EPS, DXF, EMF/WMF, several raster formats and PSD, according to the README. Jonker says PSDs arrive as a single flattened image.
• Affinity files: It opens .af from Affinity 3, plus .afdesign, .afpub and .afphoto from Affinity 1 and 2. Content that doesn't import, such as effects, adjustments, brushes and master pages, is listed in an import warning. VectorCraft does not write Affinity files.
• Illustrator .ai: Jonker says ordinary .ai files open properly only if they are PDF-compatible or very old. The team itself says real-world .ai files probably won't keep their structure reliably.
• Saving back: A third-party guide notes that a PDF-compatible .ai saved by VectorCraft reopens in Illustrator as plain art, so it won't carry editable Illustrator data.
• Export: SVG and PDF are first-class, alongside PNG, JPEG and WebP. Jonker says the export dialog offers options to minify the code or make an SVG responsive.

Keep your originals, and open any exported file in the receiving application before you send it to a client.

The AI is for agents, not a prompt box​

There is no generate button. Illustrator's Firefly features, such as Text to Vector Graphic and Generative Shape Fill, have no equivalent here.

What VectorCraft does have is automation. The README says every menu item, tool gesture, panel and dialog can be driven over a JSON control channel and an MCP server, so Claude and other agents can draw, edit and export. The README's sample artwork was built entirely through that command API. Jonker says you have to register the MCP server with Claude Code using a terminal command. I couldn't confirm that setup detail in the project's own pages. He says he would use it more if it became a button instead.

Versus Inkscape​

The layout is the main difference. Inkscape can switch its keyboard shortcuts to an Illustrator preset, Jonker says, but that doesn't move panels or rename tools. VectorCraft copies the whole Illustrator interface. I couldn't verify the shortcut-preset detail in a primary source.

Inkscape is the mature, established option. Its own release notes say 1.4.4 came out on May 6, 2026. That release is a maintenance update with 20 crash fixes, almost 20 other bug fixes, six performance improvements, and installation files for Windows on Arm. It is also a bridge release: versions older than 1.4.3 can't interpret pages created in the planned 1.5 multipage format. Jonker says 1.5 still has no release date. I couldn't verify that today, so check Inkscape's roadmap yourself.

Where to download it, and a caution​

The repository in the source packet, under the vectorcraft-app name, has one star, five commits and topics like "download-vectorcraft" and "installer". That pattern looks like download-promotion material, not the main development repository. This is my inference from those details, not a finding of wrongdoing. Other sources point elsewhere:

• The source code is listed as living under the storytold GitHub organization.
• The ArtCraft team's official site is getartcraft.com.
• WinGet lists the package as ArtCraft.VectorCraft, publisher Learning Machines LLC, version 0.22.0, according to winstall.
• vectorcraft.app describes itself as an independent site, not affiliated with the ArtCraft team. Treat it and vectorcraft.live as unofficial.

For a project that is weeks old and moving fast, that confusion is a genuine supply-chain risk. A practical approach:

• Start from getartcraft.com, or the storytold repository it links to.
• If you use WinGet, check the publisher and package ID before installing.
• Try it on a spare machine or VM first.
• Prefer the official release page over mirror and aggregator sites.

Verdict​

VectorCraft is worth a test drive if you know Illustrator and want a free alternative, or if you're curious about agent-driven design. It is alpha software. It has no generative features, Adobe file exchange is unreliable, and the Windows packaging is unfinished. Inkscape remains the safer choice for production work.

Correction (November 8, 2026): An earlier version of this article said ArtCraft is a suite of seven apps. The suite has grown since its launch; ArtCraft's official apps page now lists sixteen free, open-source apps, with the original seven standing in for the Adobe apps named above.
