Latest Grasshopper for Rhino 5.0 (Windows only)
Grasshopper requires the latest Rhino service release.
Old Grasshopper for Rhino 4.0 (Windows only)
It is possible to download the last release that still worked on Rhino 4. We keep the installer available for download but obviously this release is no longer under active development. This release requires at least Rhino 4 SR8.
Rhino for Mac OS now ships with an early alpha port of Grasshopper.
