Firefly

Rhino & Grasshopper plugin · v2.0.0 · updated 10/23/2026

New

Firefly offers a set of components bridging the gap between the Arduino microcontroller (and other input/output devices) and Grasshopper. Version 2 is a ground-up rewrite of the original Firefly plugin, running on Rhino 8 and Rhino 9, on Windows and macOS. This single package installs Firefly for Grasshopper 1, and on Rhino 9 it also installs the Grasshopper 2 version — no separate download needed.
