Yes. EasyUV Pro is licensed under GPL-3.0-or-later and the full source code is included. You can use it on your own computers for personal, commercial and client projects, and the models and UVs you make with it always belong to you. It needs no license key, no account and no internet connection.

After each run you get a result card with a quality score, island count, packing, stretch and overlap. The one-click UV Checker shows a checker texture on your model so you can see stretching right in the viewport, and you can switch it off again at any time.

Yes. Select several objects and run it once. You can give each object its own layout, or pack them all together in one shared UV space or by material group. If one object fails, the others still finish.

No. By default it creates a new UV layer named EasyUV and never overwrites your existing layers. Everything works with Undo, and if an object fails or you cancel with Esc, that object is rolled back.

No. EasyUV Pro plans the seams for you based on the shape of the model and the profile you choose. If you already drew your own seams, the Preserve seam mode keeps them. Very unusual or irregular meshes may still need a few manual touch-ups.
