You have a beautiful design in your head—a sunburst for the transom above your front door, maybe a koi pond for the bathroom window. But your photocopier just turned your perfect pattern into a mess of thick, blobby lines that look more like a melted crayon drawing than a cutting guide. If you're a stained glass artist, you know this struggle all too well.
The good news? Dedicated stained glass software has evolved dramatically over the past few years. What was once clunky, Windows-only CAD-like tools has become a diverse ecosystem of options spanning desktop, web, and iPad. Whether you're a beginner tracing your first suncatcher or a professional quoting a commission for a church window, there's a tool that fits your workflow and your budget.
I've spent the better part of two decades working with glass—both as a studio artist and as someone who's tested nearly every piece of glass art software that's crossed the market. In this guide, I'll walk you through the seven best stained glass software options for 2026, break down the free-versus-paid debate, and help you figure out which tool actually makes sense for how you work.
Why You Need Dedicated Stained Glass Design Software
Here's the thing about generic drawing tools: they're built for graphic designers, not glass artists. And the difference matters more than you might think.
The Limitations of Generic Drawing Tools
Let's talk about vector graphics editors like Inkscape or Adobe Illustrator. They're powerful—I'm not going to argue with that. But they lack the specific features that make glass pattern creation efficient rather than merely possible.
The core issue comes down to line control. In a standard vector graphics editor, a line is just a line. But in stained glass, the line width represents the space taken up by copper foil or lead came. Get that wrong, and your beautifully designed piece won't fit together when you're cutting the glass. You'll be sitting at your workbench with a grinder, trying to shave off fractions of a millimeter from pieces that are all slightly too big.
Generic tools also lack glass-specific libraries. When I'm designing, I want to see how a piece will look in Wissmach Sea Glass versus Youghiogheny Opalescent. A standard drawing program gives you a generic color picker—not a curated library of actual glass manufacturers' products with their real-world opacity and texture characteristics.
Key Features to Look For in Glass Art Software
So what should you actually look for? Based on my experience testing these tools, here's the checklist that matters:
- Pattern resizing and tiled printing: Essential for large projects. You need software that can print a pattern across multiple pages with alignment marks, so you can tape them together into a full-size template.
- Line width control: This is non-negotiable. The software should let you set a consistent line width that simulates your chosen copper foil technique or lead came width, regardless of how much you scale the pattern.
- Glass color and texture libraries: Realistic previews of actual glass products help you make better color decisions before you buy materials.
- Photo-to-pattern conversion: Not essential, but incredibly handy for turning a client's logo or a favorite photo into a starting point for a design.
- Glass quantity estimation: This feature pays for itself the first time you avoid overbuying glass for a large project.
The 7 Best Stained Glass Programs for Every Platform
After testing dozens of options—and talking with fellow artists about their workflows—these are the seven stained glass programs that consistently rise to the top.
1. Glass Eye 2000: The Professional's Choice
Glass Eye 2000 has been the industry standard for years, and for good reason. This is a serious tool built specifically for stained glass design, with features that go deep.
The 3D preview is genuinely impressive. You can see your design rendered with realistic glass textures and lighting, which is invaluable when you're presenting a proposal to a client. The glass library is extensive, with thousands of actual glass products from major manufacturers. You can apply piece numbers, generate cutting lists, and calculate material quantities with a few clicks.
But here's the honest assessment: Glass Eye 2000 has a steep learning curve. The interface feels dated—it's not going to win any design awards—and there's a lot to absorb before you're productive. It's also Windows-only, though Mac users can run it via Boot Camp or Parallels.
In my experience, this is the tool for professionals who design windows regularly and need comprehensive features. If you're making a few panels a year for fun, it's probably overkill.
2. Rapid Resizer Online: The Best for Pattern Scaling
Rapid Resizer takes a completely different approach. Instead of being a full design suite, it focuses on what many artists actually need most: taking an existing pattern and getting it to the right size, printed across multiple pages.
The web-based nature means it works on Windows, Mac, iPad, and even your phone. Upload a pattern—JPG, PNG, or PDF—and you can straighten it, crop it, adjust line widths, and print it tiled across as many pages as you need. The "Part" tool is particularly clever: you can draw a line on a specific element (say, the body of a bird) and tell the software what size that element should be, and it resizes the entire pattern around that constraint.
There are three pricing tiers: Basic, Designer, and Pro. The Basic version handles resizing and printing. Designer adds drawing tools for creating original designs. Pro adds glass color selection and quantity estimation.
The main limitation? It's not a full design tool. If you want to create complex original patterns from scratch, you'll find the drawing tools basic compared to dedicated design software.
3. Inkscape: The Best Free Stained Glass Software
Let me be direct: Inkscape is not stained glass software. It's a free, open-source vector graphics editor. But with some know-how, it can be adapted into a powerful tool for glass pattern creation.
The key feature is "Stroke to Path," which lets you convert a line into a filled shape with a specific width. This is how you control line widths for foil or lead. You can also use extensions and plugins to add glass-specific functionality, though you'll need to hunt for them and be comfortable with some trial and error.
The learning curve is significant. I've seen beginners get frustrated within an hour of opening it. But the cost is zero, and the community support is excellent. There are countless tutorials, forums, and YouTube videos specifically about using Inkscape for stained glass patterns.
For hobbyists on a budget, Inkscape is genuinely viable. For professionals, the lack of glass libraries and automated features means you'll spend more time on manual workarounds.
4. Procreate: The Best Stained Glass App for iPad
Procreate has become a phenomenon in the digital art world, and it's easy to see why. The touch interface is intuitive, the Apple Pencil support is flawless, and the brush engine is incredibly versatile.
For stained glass, Procreate shines as a design tool rather than a production tool. I know several artists who use it for the initial creative phase—sketching ideas, experimenting with color palettes, playing with composition. The ability to work on a canvas that feels like paper, with the undo button always available, is liberating.
But here's the limitation: Procreate isn't built for precision pattern work. You can't easily set exact line widths, tile patterns across multiple pages, or generate cutting lists. It's a one-time purchase (around $13), which makes it an affordable addition to your toolkit, but it shouldn't be your only tool if you're serious about pattern production.
5. Affinity Designer: The Affordable Vector Alternative
If you're looking for a vector graphics editor that's more powerful than Inkscape but doesn't require a subscription like Adobe Illustrator, Affinity Designer is worth serious consideration.
It's a one-time purchase—around $70—and it runs on both Mac and Windows. The vector tools are robust, and you can create clean, scalable patterns with precise control over line widths. The interface is modern and intuitive, especially if you're coming from Illustrator.
The trade-off is the same as with Inkscape: it's not glass-specific. You won't find glass libraries or quantity estimation. But if you're comfortable with vector design and want a professional-grade tool without the subscription, Affinity Designer is an excellent middle ground.
6. Krita: The Free Digital Painting Option
Krita is another free, open-source program, but it's focused on digital painting rather than vector design. That makes it a different kind of tool for stained glass artists.
Where Krita excels is in creating artistic, painterly designs. If you want to design a panel with flowing, organic shapes that feel more like a painting than a geometric pattern, Krita's brush engine gives you incredible freedom. You can sketch, paint, and experiment with textures in ways that vector tools make difficult.
The limitations are real, though. Krita isn't built for precision drafting. You'll struggle with exact measurements, consistent line widths, and pattern tiling. It's a design tool for the creative phase, not a production tool for creating cutting templates.
7. Dragonfly Software: A Niche Tool for Pattern Creation
Dragonfly Software is a lesser-known option, but it deserves attention. It's a dedicated tool for creating and editing stained glass patterns, positioned as a middle ground between free tools and professional suites like Glass Eye 2000.
The standout feature is the "Pattern Wizard," which guides you through creating a pattern step by step. There's also a library of pre-made shapes and elements you can combine and customize. It's not as powerful as Glass Eye 2000, but it's significantly easier to learn.
The main drawback is that Dragonfly Software feels a bit dated, and development seems to have slowed. It's a niche tool for a specific workflow, not a comprehensive solution.
Free vs. Paid Stained Glass Software: What's the Real Difference?
This is the question I get asked most often, and the answer isn't as straightforward as you might think.
Can Free Software Like Inkscape Replace Paid Options?
Let's compare Inkscape and Glass Eye 2000 directly. Both can create patterns, control line widths, and print tiled pages. But the experience is fundamentally different.
In Inkscape, you'll need to learn how to use "Stroke to Path," manually set up your document for tiled printing, and create your own color reference system. It's doable—I've done it—but it takes time and patience.
In Glass Eye 2000, these features are built in. You set your line width, and the software handles the rest. You apply glass colors from actual manufacturer libraries, and the software generates a cutting list with quantities.
For hobbyists making a few projects a year, the time investment in learning Inkscape is often worth it. For professionals who design regularly, the efficiency of paid tools pays for itself quickly.
The Hidden Costs of 'Free' Tools
Here's what people often overlook about free software: the cost isn't always zero.
With Inkscape, you might find yourself downloading plugins and extensions to add glass-specific features. Some are free, but others are paid. You'll also spend time troubleshooting issues and searching forums for solutions—time that could have been spent designing.
Open-source projects also lack dedicated customer support. If something breaks, you're on your own. Commercial software typically includes support, and in my experience, the support from companies like Dragonfly Software and Rapid Resizer is responsive and helpful.
How to Choose the Right Stained Glass Program for Your Needs
So which tool should you choose? Here's my practical advice, based on where you are in your stained glass journey.
A Decision Guide for Beginners, Hobbyists, and Professionals
For beginners: Start with Inkscape. It's free, which means you can learn without financial pressure. The learning curve is steep, but the skills you develop—understanding line widths, working with vector paths—will transfer to other tools later.

Frequently Asked Questions
What is the best stained glass program for beginners?
For absolute beginners, I'd recommend Inkscape. The zero cost means you can experiment without commitment, and the extensive community support means help is always available. That said, if you're working primarily with existing patterns and need to resize them, Rapid Resizer's user-friendly interface makes it a strong contender. The "best" choice depends on whether you want to design from scratch or resize existing patterns.
Is there a free stained glass design software that can control line width?
Yes—Inkscape can do this using the "Stroke to Path" feature. You draw your line, convert it to a path, and then set the width to match your foil or lead. It's not as automated as paid software, but it's a powerful free alternative. There are also extensions available that add glass-specific functionality.
Can I use stained glass software on my iPad?
Yes, with some caveats. Procreate is excellent for design work and sketching, and web-based tools like Rapid Resizer work in iPad browsers. However, for precise pattern tiling and printing, a desktop or web-based solution is often more practical. The iPad is best for the creative phase, not the production phase.
What is the difference between stained glass software and regular drawing software?
Dedicated stained glass software includes features like line width control for foil and lead, glass color and texture libraries from actual manufacturers, pattern tiling for large prints, and glass quantity estimation. Regular drawing software lacks these specialized tools, which means you'll need to create workarounds for each of them.
Making the Right Choice for Your Studio
Here's the honest truth: there's no single "best" stained glass software. The right choice depends on your skill level, your budget, and the platform you prefer to work on.
If you're just starting out, download Inkscape and give it a try. The learning curve is real, but the skills you develop will serve you well. If you're a hobbyist who wants to spend more time cutting glass and less time wrestling with software, Rapid Resizer is worth the subscription. And if you're a professional who designs regularly, Glass Eye 2000's comprehensive features will pay for themselves.
My advice? Take advantage of free trials and free versions. Most paid software offers some form of trial, and the free tools have no barrier to entry. Test a few options, see which one feels natural to you, and don't be afraid to use different tools for different phases of your work.
