FabTools by Florian Frank is a set of Clusters, that enhances the ability of Grasshopper. The Tools are for fabrication purposes in Grasshopper and improve your workflow and accelerate your scripting tasks.

Silkworm by Karl Adam, Arthur and Andrei – The Silkworm Team, is a plugin that translates Grasshopper and Rhino geometry into GCode for 3d printing.

Peregrine is a LimitState:FORM powered optimization plugin for Grasshopper, the visual programming language and environment for Rhino3D.

SeaGrass is an adaptive surface panelling tool, that helps create Louvered Panels. SeaGrass is built against Grasshopper 1.0 (for Rhino 6.0). 

OpenNest by petras_vestartas is a Grasshopper plugin with tools for unrolling, packing and of course nesting curves directly inside the definitions. The library is based on Boost 1.62 that is used to compute NFP – No Fit Polygon.

3D Graphic Statics by Ognjen Graovac is a structural form-finding method for generating compression-only spatial forms. The static equilibrium is described by using two reciprocal diagrams – form and force. 

flowL by uto is a plug-in to visualize a vector field, generated through positive and negative point charges. The path lines are calculated with the “Runge-Kutta 4th Order Method” short “RK4”.

Wasp by Andrea Rossi is a set of Grasshopper components, developed in Python, directed at representing and designing with discrete elements. The description of each individual part includes basic information necessary for the aggregation process.

AXOLOTL by worbit provides a set of components for volumetric modeling in Rhino Grasshopper. They work based on the principle of signed distance functions (SDF).

SuperMesh Toolkit by George Adamopoulos allows you to easily design a large variety of regular or irregular patterns on NURBS Surfaces of any curvature, by tessellating them to special quad-like Meshes, topologically structured in rows and columns.

The Rhinoceros® Plug-In RhinoVAULT by Matthias Rippmann emerged from current research on structural form finding using the Thrust-Network-Approach to intuitively create and explore compression-only structures. 

Discrete Vectors by ekimroyrp is a set of components for making discrete vectors out of continuous or random vector sets. Good for matching vectors to other closest predefined vectors to give curves, swarms, and flowlines that straight line aesthetic.

BrickDesign by ROB Technologies enables the controlled design and manipulation of a large amount of discrete elements. The plug-in provides a parametric design environment, which allows for a fast build-up of brick façade geometries.

Anemone by Mateusz Zwierzycki  enables you to create loops in Grasshopper. The basic workflow relies on two main components : Loop Start and Loop End

PanelingTools plugin by Robert McNeel & Associates is integrated with Rhino and Grasshopper and is widely used by designers, architects, and building prefessionals. It supports intuitive design of paneling concepts as well as help rationalize complex geometry.

Flatworm by jakobl is a GHPython implementation of the pure-python module RFQM.py for generating ‘rigidly foldable quadrilateral meshes’ (RFQM) in Grasshopper. Flatworm provides basic means of generating Miura Ori fold pattern as well.

Chimpanzee by matous111 is a Grasshopper plug-in for Rhino 6 written in Python which focuses on fractal math and chaos theory. Chimpanzee contains currently 71 components.

TPS by C.Robeller is a Grasshopper Plugin for the design of freeform Timber Plate Structures. It is meant for discrete structures, built from separate pieces which are connected with joints. The resulting meshes are not necessarily flat-foldable as in Origami.

Intralattice by dnkrtz, is a plug-in for Grasshopper used to generate solid lattice structures within a design space. It was developed as an extensible, open-source alternative to current commercial solutions, such as Within.

Cocoon by David Stasiuk is an add-on to McNeel’s Grasshopper visual scripting interface for Rhinoceros. Cocoon is a fairly straightforward implementation of the Marching Cubes algorithm for turning iso-surfaces into polygonal meshes.
