Best Laser Engraving Software in 2026 (LightBurn vs the Alternatives)

Quick Answer: For most diode and CO2 laser owners, LightBurn is the software to buy — Core costs $99 one-time for GRBL diode machines and Pro costs $199 one-time for Ruida/Trocen DSP and galvo controllers, per LightBurn’s official pricing. Fiber and UV laser owners should stick with EZCad2, the free control software that ships with almost every fiber marking machine sold today, since LightBurn’s fiber support is still experimental on many controllers. Budget-conscious GRBL owners can start with LaserGRBL (free, Windows-only) before paying for LightBurn Core.

Every laser engraver ships with some software in the box, but “what came with it” and “what you should actually run” are often two different answers. The right pick depends entirely on your machine’s controller — not your budget or experience level — and picking wrong means paying twice or discovering mid-project that your software can’t talk to your laser at all. This roundup ranks the software that actually matters in 2026: what each one costs, which controllers it supports, and when the free option that shipped with your machine is genuinely good enough.

Laser engraving software at a glance

By the numbers

• LightBurn Core’s price is $99 one-time, not the $120 you’ll still see quoted on older reviews — LightBurn renamed its GCode license to “Core” and repriced it in a licensing change that took effect October 1, 2024, per LightBurn’s own pricing pages. Pro remains $199, and the Core-to-Pro upgrade path costs exactly the $100 difference between them.
• EZCad2 ships free with virtually every consumer and small-business fiber laser sold today — it’s the default control software from JCZ-based galvo boards, the same controller family used across ComMarker, OMTech fiber, and most white-label fiber engravers.
• LaserGRBL and RDWorks are both Windows-only, so a household running Mac hardware needs a dedicated Windows PC or virtual machine for any GRBL or Ruida machine that isn’t run through LightBurn instead.

1. LightBurn Core — Best Overall for Diode Lasers

Buying the license today and a controller-matched machine to go with it? A free 30-day Amazon Prime trial gets both to your door in two days instead of waiting on standard shipping.

LightBurn Core is the software nearly every diode laser buyer ends up running, and the $99 price is a genuine correction worth knowing if you’ve seen the older $120 figure floating around — that was the price before LightBurn’s October 2024 license restructuring, and a lot of laser content on the web (including an older page on this site) never caught up. Core covers xTool, Sculpfun, AtomStack, Creality Falcon, Ortur, and Longer — essentially every GRBL-family diode machine — and its material test-grid tool alone saves more scrap material than the license costs in the first month of real use. See our what is LightBurn guide for the full breakdown of when you’d need Pro instead.

2. LightBurn Pro — Best for CO2 and Galvo Machines

Pro is the license to buy the moment a Ruida or Trocen DSP controller enters your shop — every OMTech, Monport, and Boss-style CO2 tube laser on the market runs one of those two boards. The $100 upgrade path from Core is exact math, not a marketing number: $199 Pro minus the $99 you already spent on Core. If cost is the only reason you’re hesitating, buy Core now for a diode machine and upgrade later rather than guessing which tier to buy first.

3. EZCad2 — Best for Fiber Lasers

Fiber and UV galvo laser owners should skip LightBurn entirely and run EZCad2, the free software that ships in the box with nearly every fiber marking machine sold to small businesses — including the JCZ-based boards used across ComMarker and most fiber engravers on the market. The interface is dated and the learning curve is real compared to LightBurn’s cleaner layout, but EZCad2 handles batch marking, array jobs, and automatic serial-number incrementing — production features fiber shops actually need — more reliably than LightBurn’s still-experimental fiber support. It’s Windows-only, and there’s no official Mac build, so factor that into your workstation setup if you’re adding a fiber laser to an all-Mac shop.

4. RDWorks — Best Free CO2 Option

RDWorks is the free software Ruida DSP controllers ship with, and it’s a legitimate way to skip LightBurn Pro’s $199 license if you’re running a single CO2 machine and don’t need LightBurn’s more polished material-test workflow. It handles vector and raster import, CAD-file cutting, and multi-pass jobs, and it’s been the default for entry-level Chinese-built CO2 lasers for years. The tradeoff is the same one every free bundled app carries: a dated, less intuitive interface, Windows-only, and no cross-brand support if you ever add a diode or fiber machine to the same shop.

5. LaserGRBL — Best Free Diode Option

LaserGRBL is the software to try before spending $99 on LightBurn Core if you’re on a tight budget or just testing whether a laser hobby sticks. It’s free, open-source, and its raster-to-laser dithering is genuinely good for a no-cost tool, backed by a crowd-sourced material-settings library from the user community. The gaps show up in vector design — LaserGRBL isn’t a drawing program, so most users pair it with the also-free Inkscape for layout before importing the finished file. It’s GRBL-only, so it won’t touch a CO2 or fiber machine, and it’s Windows-only like most of the free options on this list.

6. xTool Creative Space (XCS) — Best for xTool Owners

xTool Creative Space is the free app xTool bundles with every machine it sells, and it’s worth a real look before assuming you need LightBurn on day one. XCS includes a built-in material library tuned specifically to xTool’s own hardware, camera-based positioning on models that support it, and a cleaner onboarding flow for first-time laser owners than LightBurn’s more general-purpose interface. It runs on Windows, Mac, iOS, and Android — the only software on this list with mobile support — which matters if you want to queue a job from a phone across the shop. The ceiling is real, though: XCS lacks LightBurn’s offset/kerf handling and cross-brand flexibility, so xTool owners who add a second brand’s machine later typically switch to LightBurn Core at that point rather than run two separate apps.

How to choose your laser engraving software

Check your controller before anything else. GRBL/Smoothieware/Marlin (nearly every diode laser) → LightBurn Core or free LaserGRBL. Ruida or Trocen DSP (most CO2 tube lasers) → LightBurn Pro or free RDWorks. Fiber or UV galvo → EZCad2, not LightBurn. Budget decides Core vs. free: if you’re running more than a handful of jobs a week, LightBurn’s material test-grid and offset/kerf tools pay for the $99 Core license fast; if you’re testing the hobby first, start with the free bundled or open-source option and upgrade once you outgrow it. Cross-brand shops always land on LightBurn — it’s the only option on this list that runs GRBL and DSP machines from a single app, which matters the moment a second laser brand joins the shop.
