LaserGRBL vs LightBurn: Which Software Should You Use?

Both connect your computer to a diode laser. LaserGRBL is free and simple; LightBurn Core costs $99 and does substantially more. Here's the honest breakdown — and when each one actually makes sense.

What Each Program Actually Is

Both LaserGRBL and LightBurn do the same core job: they take a design you want to engrave or cut, convert it to machine instructions (G-code), and send those instructions to your laser over USB. Everything else is where they diverge.

LaserGRBL is a free, open-source program written by Italian developer Claudio Cursi. It's a relatively thin controller layer: you bring an image or SVG, configure some settings, and send it to your machine. It's designed for GRBL-based machines — the standard controller used in most budget diode lasers — and it works reliably without fuss. The interface is dense but not complicated once you've spent an hour with it. It doesn't try to be a design application.

LightBurn is a commercial application from LightBurn Software. It costs $99 for LightBurn Core (the license that covers most diode lasers via GRBL/G-code), and it covers design, layout, and machine control in a single package. Think of it as Illustrator-light plus a laser controller fused together: you can draw shapes, import SVGs, set up multi-layer jobs, assign cut priorities, preview burn times, and then send the job — all without leaving the app.

Side-by-Side Feature Comparison

LaserGRBL: Strengths and Limitations

LaserGRBL's main strength is that it costs nothing and works. For someone who just wants to engrave a logo or a photo onto wood or leather and doesn't need to learn a full application, it's genuinely good. The image conversion wizard handles the basics: you load an image, choose a dithering algorithm, set speed and power, and go.

A few things LaserGRBL does well:

• Photo engraving: The built-in image conversion is decent. Jarvis dithering is usually the best starting point for woodgrain and leather. You can invert, resize, and adjust brightness/contrast before converting.
• Running G-code files: If you generate G-code in a different program (Inkscape with a plugin, Carbide Create, etc.), LaserGRBL can send it to your machine reliably.
• Quick, low-stakes jobs: Single-layer, single-material jobs work fine. You won't miss layers or cameras if you never needed them.

Where LaserGRBL struggles:

• Vector cutting: LaserGRBL can handle simple SVGs, but managing cut order, combining engraving and cutting in the same job, or controlling which paths get which settings is painful. There's no real layer system.
• Multi-step jobs: Any job where you want to engrave at one setting and cut an outline at a different setting requires workarounds or multiple runs.
• Rotary work: Wrapping around tumblers requires calibrating your rotary in G-code manually. LightBurn has a guided wizard; LaserGRBL does not.
• Non-Windows users: Full stop — there is no Mac or Linux version. If you're on a Mac, LaserGRBL is not an option.

Does LaserGRBL Work on Mac or Linux?

Mac and Linux users have three realistic alternatives, each covering a different situation:

For the vast majority of Mac users with a standard diode laser (xTool, Sculpfun, Ortur, Atomstack), LightBurn Core is the right choice. Download the 30-day full-featured trial, connect your machine, and decide by day 3 whether it's worth the $99. The trial has no limitations — you can run real jobs on your actual laser the first day.

Running LaserGRBL via Parallels or a Windows virtual machine on a Mac is technically possible but not recommended. USB passthrough in virtual machines is unreliable with GRBL devices, you'll spend more time troubleshooting VM drivers than learning your laser, and the result is slower and less stable than native LightBurn running directly on macOS.

LightBurn: Strengths and Limitations

LightBurn is the tool the majority of serious hobbyists and nearly all small-business laser operators use. The $99 price is the main barrier — but the 30-day trial is full-featured, so you can decide before paying anything.

The layer system changes everything

Every shape or image in your job sits on a layer. Each layer gets its own speed, power, fill mode, and priority. A typical job might have a "Photo" layer (low power raster engrave), a "Text" layer (medium power fill), and a "Cut outline" layer (full power line, runs last so pieces don't move while engraving). In LaserGRBL, setting this up means running three separate jobs. In LightBurn, it's one job you hit Start on once.

Material library

Save your settings per material and laser power. Once you dial in 3mm basswood cutting on your 20W machine, you save it to your material library and never have to remember it again. This alone is worth the cost of entry if you work with more than two or three materials.

Rotary support

LightBurn has a dedicated rotary setup wizard that measures steps-per-rotation for roller and chuck rotaries, lets you specify the object diameter, and automatically scales your design to wrap correctly. It also lets you test rotation before running a full job. Doing rotary work in LaserGRBL requires manually editing G-code or using third-party scripts.

Camera alignment

Attach a webcam to your laser, calibrate it once in LightBurn, and you get a live overlay of your material in the workspace. You can position designs visually on your actual piece instead of measuring. Extremely useful for working with pre-made blanks or placing graphics in a specific spot on a piece of wood.

LightBurn's limitations are minor but worth knowing:

• It costs money. For someone with a $150 laser doing one or two projects a month, the $99 license represents two-thirds of their machine cost. That's a legitimate concern.
• Update license after year one. The initial $99 covers the software and one year of updates. After that, updates cost $40/yr — optional, but LightBurn is actively developed and the updates include real features. You can stay on your existing version forever if you don't want to pay.
• Learning curve on the layer system. It's not hard, but it does require an hour of orientation. The documentation and YouTube tutorials are excellent, though.

How Much Does LightBurn Actually Cost?

LightBurn's pricing is simpler than it sounds. For anyone with a diode laser (GRBL-based machine), there is really only one license to consider:

After year one, software updates are optional at $40/yr. Your existing version never stops working — you can stay on it indefinitely. Most hobbyists pay the update fee one more time (to get rotary improvements or new fill modes) and then stop. There is no monthly subscription, no cloud account requirement, and no per-seat fee if you run it on two computers (the license is transferable).

What About xTool Creative Space?

If you own an xTool machine, a third option exists: xTool Creative Space (XCS), xTool's own proprietary software. It's free, works on Mac and Windows, and is designed specifically for xTool machines. For some xTool models (including the S1 enclosed laser), XCS is actually required because those machines use a proprietary protocol LightBurn can't speak.

XCS is getting better with each release — it now supports layers and has decent camera features for the xTool machines that include a built-in camera. It's worth trying if you have an xTool machine and want to stay in a supported ecosystem. But for advanced users doing complex work, LightBurn (when compatible) remains more capable.

Check LightBurn's supported devices list before buying a license to confirm your specific xTool model is supported. For a full model-by-model breakdown — and a comparison of XCS vs LightBurn features — see our dedicated xTool Creative Space vs LightBurn guide.

Which One Should You Start With?

The practical answer depends on two things: your budget and your operating system.

One note on the $99 question: if you're running a small business making tumblers, signs, or personalized items, LightBurn pays for itself in the first week. The time savings from the material library and rotary wizard alone justify the $99. For a pure hobbyist who engraves a few Christmas ornaments a year, the calculus is different — but the 30-day trial lets you make that call with actual experience rather than guessing.

Can You Use Both? Can You Switch?

Yes to both. You can run LaserGRBL and LightBurn on the same computer without any conflict — they're independent applications. Some people use LaserGRBL to run pre-generated G-code from CAD tools while using LightBurn for everything else.

Switching from LaserGRBL to LightBurn later is seamless. There are no files locked in a proprietary format — your designs are typically SVGs or images that import fine into LightBurn. The machine connection is the same USB cable and GRBL firmware you were already using.
