Zuv Tools is listed on Superhive and carries a GPL license. The developer has noted it is no longer in active development and has invited others to continue the project.
Zuv Tools adds a set of UV operators to Blender's UV toolset covering selection, spreading, smoothing, and manipulating. Its main tools include Shortest Path, which finds the shortest path between two selected UVs according to the chosen algorithm and source; Spread, which straightens selected UVs and spaces them evenly or according to their distances on the mesh; Smooth, for smoothing selected UVs; Circle, which turns selected UVs into a circle; and Transfer Selection, which transfers selected UVs between UV sync modes.
The 2.5 release adds tools such as Randomize, Boundary Select, an improved Hide, and Gridify Islands, which turns any four-cornered island made of quads into a spread grid with auto spread and auto ratio applied. Default keymaps were added for Copy, Paste, Shortest Path, Hide Better, Rip, Auto-Weld, and Spread. An Auto "Redo UVerts" behaviour recalculates UVerts on the fly to reduce interrupts.
The developer has stated that Zuv Tools is no longer in active development. Version 2.5.1 includes fixes for Blender 3.6 and 4.1. Full documentation lists the complete feature set.
Zuv Tools is best for blender artists who want additional selection, spreading, smoothing, and manipulation tools in the UV editor.
Zuv Tools is completely free to download and use.
Zuv Tools lists Blender 4.1 and 3.6 as its supported versions. The 2.5.1 release specifically includes fixes for Blender 3.6 and 4.1, so those are the versions the add-on has been maintained against. If you run a different Blender version, check the developer's page and documentation for compatibility details before relying on it, since behaviour on untested versions is not stated here.
Zuv Tools is no longer in active development. The developer has stated they do not see new features coming in the future, explaining that the add-on was built alongside a job they have since left and that they no longer have time to maintain it. They have also invited anyone interested in continuing the project to reach out. The most recent release is version 2.5.1, which includes fixes for Blender 3.6 and 4.1.
Zuv Tools is listed as free in this catalog and carries a GPL license, according to the details published on its page. For current licensing terms and any conditions attached to the download, refer to the developer's page rather than relying on this listing alone. The add-on is distributed through Superhive, where its details, documentation, and licensing information are published under the developer Zach Eastin. Because it is no longer in active development, check there for the most accurate, up-to-date information before installing.
Zuv Tools includes Gridify Islands, added in the 2.5 release, which turns any four-cornered island made up of quads into a spread grid, with auto spread and auto ratio applied. It is one of several new tools introduced in that version alongside Randomize, which randomizes the location of selected UVs within a set distance, Boundary Select, and an improved Hide behaviour. A demo video is available for reference.
