LightBurn has been the gold standard for laser engraver software for years, and for good reason. But its move to a subscription pricing model has pushed many hobbyists to explore alternatives.
Under the current pricing, a GCode license (for GRBL and Marlin machines) costs around $60 per year. If you need DSP support for CO2 lasers with Ruida or Trocen controllers, that jumps to $120 per year. LightBurn previously offered a one-time perpetual license, and the switch to annual renewals was met with significant pushback from the community.
For hobbyists who own a single GRBL-based diode laser and use it on weekends, paying $60 or more every year can feel excessive. Many of these users only need the basics: importing an image, choosing a dithering algorithm, and sending GCode to their machine. They might do some simple SVG cutting on the side. Paying a recurring fee for advanced features they never touch is hard to justify.
That said, LightBurn remains the most capable option for professional and advanced users. Before looking at alternatives, it is worth understanding what makes it so popular.
Let's be fair: LightBurn earned its reputation. It is a genuinely excellent piece of software, and for many users it is still the right choice.
If you own a CO2 laser, work across multiple operating systems, or rely on camera alignment and rotary features, LightBurn is hard to beat at any price. The subscription model is easier to stomach when you are using the software professionally or depend on its full feature set.
Several free options exist, though each comes with trade-offs. Here is an honest look at the most common ones.
LaserGRBL is the most popular free laser engraving software. It is open-source, well-maintained, and has a solid community behind it. For basic image engraving on Windows, it gets the job done.
The main limitations: it only runs on Windows (no Mac, no Linux), it has no SVG cutting support, and the user interface feels dated. It also lacks advanced features like layer management or project files. But if you are on Windows and just want to engrave photos onto wood, LaserGRBL is the go-to free option. If you are on a Mac and looking for a LaserGRBL replacement specifically, see our dedicated LaserGRBL alternatives for Mac guide.
LaserWeb is a browser-based, open-source tool that runs on any platform. It supports both raster engraving and vector cutting, and works with GRBL, Marlin, and Smoothieware controllers.
The downsides are significant: the setup process involves running a local server, the project is not actively maintained, and the interface can be overwhelming for beginners. If you are technically inclined and willing to invest time in configuration, LaserWeb is capable. But it is not something most hobbyists would describe as user-friendly.
UGS (Universal Gcode Sender) is a Java-based CNC controller that works on Mac, Windows, and Linux. It can send GCode to any GRBL machine, including laser engravers.
However, UGS is a CNC sender, not a laser-specific tool. It has no built-in image processing, no dithering algorithms, and no raster engraving pipeline. You would need to generate your GCode in another application and then use UGS purely as a sender. For laser users, it works in a pinch but is not a complete solution.
K40 Whisperer is a free tool designed specifically for the cheap K40 CO2 laser cutters that use a Lhystudios (M2 Nano) controller board. If you have a K40, it is an essential tool. If you have anything else, it will not work with your machine.
Lùmen is a native macOS application built specifically for GRBL-based diode lasers. It takes a focused approach: instead of trying to support every controller and every platform, it does one thing well — controlling GRBL lasers from a Mac.
Key features include:
The price is €9.99 one-time. No subscription, no yearly renewal. That is roughly what two months of a LightBurn GCode subscription would cost.
The trade-offs are clear: Lùmen only works on macOS, and it only supports GRBL controllers. There is no camera alignment, no rotary support, and no built-in vector editing. If those limitations match your setup — a Mac and a GRBL diode laser — it is an excellent value.
Download Lùmen and try it with your machine.

| SVG Cutting | Yes | No | Yes |
| Camera Alignment | Yes | No | No |
| Rotary Support | Yes | No | No |
| Layer System | Yes (multi-layer) | No | Yes (dual layer) |
| Project Files | Yes | No | Yes |
| Native Mac App | No (cross-platform) | No | Yes (SwiftUI) |
LightBurn is worth the subscription if any of the following apply to you:
In short, if laser engraving and cutting is a significant part of your workflow — whether professional or as a serious hobby — and you use the advanced features, the subscription pays for itself.
On the other hand, an alternative is worth considering if:
LightBurn remains the most feature-rich laser software available. Its subscription model makes sense for users who rely on its advanced capabilities daily. But not everyone needs everything LightBurn offers.
If you are a Mac user with a GRBL diode laser, Lùmen gives you image engraving with 7 dithering algorithms, SVG cutting, a dual layer system, and device presets for a one-time €9.99. No subscription, no recurring fees.
If you are on Windows, LaserGRBL is free and handles basic engraving well.
Pick the tool that matches your machine, your platform, and your budget. The best software is the one you will actually use.
