The short answer
Yes — LightBurn is worth it if you run one well-supported laser and want the broadest device support, a polished single-machine workflow and a large community. For that use, the license is easy to justify. It is less worth it if you want to start free, work natively on a Mac, manage several machines, each in its own tab, or have image, vector and relief prep built in. In those cases it is worth weighing Vextrify first, since it has a free browser preview and covers exactly those gaps.
- Worth it: broad device support, one machine, mature workflow
- Less ideal: free start, Mac, multi-laser, built-in prep
- Weigh Vextrify for those gaps
