Fractal Explorer stands out in the Superhive library because it hands shape control to Blender's own transform tools rather than fixing the form itself, so no math is required to build branching fractals.
Fractal Explorer generates 3D fractals in Blender using any base object as a starting point. It builds a nested, tree-like structure of copies, parenting each copy to the previous one and constraining them to inherit transforms. The first generation of copies stays free to manipulate, and any change to their location, rotation, or scale propagates through the whole tree. The shape is not set by the plugin: you decide the structure with Blender's normal transformation tools, and no math is required.
Because it produces a branching tree rather than a single chain of copies, it can express branching and more complex fractals. You can set the depth of the tree, the geometry, and how many branches per copy. The developer notes it suits fractal-like natural forms such as trees, corals, veins, and clouds, and the fractals can be animated.
Fractal Explorer is not a modifier, which brings some quirks. Modifiers applied to the base object after the tree is generated will not affect all copies, though the documentation describes a workflow around this. Deep trees produce enormous copy counts and slow Blender down, so "grow tree" and "prune tree" buttons let you work at a low level and crank it up for final render or export.
Fractal Explorer is best for blender users experimenting with fractal geometry and modeling fractal-like natural forms such as trees, corals, veins, and clouds.
Fractal Explorer is completely free to download and use.
Fractal Explorer lists compatibility with Blender 2.7x, 2.8, 2.81, 2.82, 2.83, and 3.1. If you run a version outside this range, check the developer's page for current details before relying on it. The tool builds its fractal structure using Blender's native rotate, translate, and scale tools and its parenting and constraint system, so a compatible Blender install is the main requirement for working with it as described.
Fractal Explorer creates a branching tree of copies, while Blender's Array modifier can only create a chain of copies. The Array modifier is well suited to spiral fractals when you input an empty in the Object Offset field, but it cannot express branching or more complex fractals. With Fractal Explorer you specify the depth of the tree, the geometry using Blender's native transformation tools, and how many branches per copy.
Fractal Explorer builds a geometric series of copies, so depth multiplies quickly: a fractal with 5 branches and 10 levels reaches over 12 million copies. That is a large number of copies and constraints for Blender to track, which slows it down. To manage this, Fractal Explorer includes "grow tree" and "prune tree" buttons, so you can settle on a shape at a few levels and then increase the depth for final render or export.
Fractal Explorer is listed as free in this catalog and is distributed under the GPL license. For current licensing terms and any purchase or contribution options, check the developer's page. The add-on comes with documentation that gives a more detailed explanation of how the nested tree structure works, along with a workflow for applying modifiers after the tree has been generated, which does not otherwise affect all copies.

Profile Rails Extruder is a Blender addon that extrudes a flat face profile into 3D space along a rail. Unlike Blender's curve bevel, the profile shape stays unchanged by the rail's direction rather than tapering.
