Free LightBurn alternative

The most common free LightBurn alternative is LaserGRBL, but it only runs on Windows and only controls GRBL diode lasers. Rayforge is free and open source, runs on Windows, macOS and Linux, drives GRBL machines and has camera alignment. MeerK40t is free and open source, good for K40 CO2 lasers, but more technical and in maintenance mode. Vextrify is free to try in the browser: load your own photo and see the prepared result at no cost. Exporting needs a Studio plan, and live machine control needs Studio Pro or the 24-hour desktop trial. None of the free controllers prepares photos properly; that is the gap Vextrify's free browser preview addresses.

• Free Windows diode control → LaserGRBL
• Free control on Mac or Linux → Rayforge
• Free open-source K40 → MeerK40t
• Free photo and layout prep → Vextrify browser tier

LaserGRBL is the go-to free controller for GRBL diode lasers, and it is genuinely capable for that job. But it is Windows-only, so it will not help Mac users at all, and it does not support CO2/Ruida or fiber machines. Its image preparation is basic, so photo engraving usually needs another tool first.

• Free for GRBL diode lasers
• Windows-only — no Mac
• Basic image prep

Vextrify's free browser preview lets you load your own photo and see the prepared result at no cost, on macOS, Windows or even a Chromebook. Exporting needs a Studio plan; live machine control — including managing several machines, each in its own tab — needs Studio Pro or the 24-hour desktop trial. It is the rare free starting point that does not lock Mac users out.

• Free browser preview on any platform
• Background removal, SVG and photo prep included
• Upgrade for live machine control

Free laser software trades away breadth or polish. LaserGRBL gives up platform and device range; Rayforge is young and its Ruida support is experimental; MeerK40t gives up ease of use; Vextrify's free browser preview shows your photo prepared, with live machine control on paid plans. Knowing the trade-off up front saves frustration — and none of these locks you in, since Vextrify can also export clean files for LightBurn or Ruida.

• Free always trades away something
• Match the trade-off to your machine and platform
• Vextrify exports to LightBurn/Ruida if you switch

Create a free Vextrify account and load a photo in the browser to see it prepared — no install, no Windows requirement. If you only need basic GRBL diode control on Windows, LaserGRBL is a fine free companion. Many people try Vextrify free first and add a plan later.

• Free Vextrify account, no install
• Works on Mac, Windows and Chromebook
• Add live control when you need it
