Start scripting

The same nodes, literally

Create, edit, and share Grasshopper scripts in the browser. No installs needed.

Start scripting

Share a link, not a file

Scripts shared on NodePen open with controls you choose, on any device, public or private. No more dragging those sliders all the way left.

Publish a script

One script, one place

Build together in the same script, live or async. Your team's work versioned, permissioned, and safe for as many people as you can throw at it.

Invite your team

Features

Run literal Grasshopper scripts on the web. And then some.

Actual Grasshopper, right in your browser

Powered by Rhino Compute: create the same scripts you would in your desktop environment. But it runs on not your computer. Never wait again for the solver to finish before you can keep working.

Try it now

Live 3D preview

See your geometry update in a "second window" while you work. No thread to lock, no machine to crash.

Background model import

Upload models, then reference and build off of their geometry. We like breps here.

Mobile viewing

Edit on the desktop, share on your phone: scripts can be viewed, including their results and controls, from any device.

Familiar feel

NodePen is not Grasshopper. But it's not not Grasshopper. Reach for the same hotkeys and interactions we use every day.

Build scripts as a team, not in isolation

Invite people to your team, work in live multiplayer or async, and keep a history of what changed and why.

Try it now

Realtime multiplayer

Literally. Same document, same time, cursors and all. No sales speak here: this is just very fun and very chaotic.

Version history

Checkpoint work and give your team something to view, compare, or roll back to.

Team libraries

Share a private and standard library of scripts for daily work. Build it together.

Access control

Control who can work where, with view and edit permissions.

What's next for NodePen

Lots left to do. Some fun, some boring, some now, some later.

This month, probably

Version diffing

Visually compare two script versions to see exactly what changed in the graph.

Clusters

Split large tasks up into smaller, assignable chunks of the script. Control who can edit them.

Groups

Stay organized. You animals.

Next month, almost definitely

Scripting components

Execute custom python and dotnet code.

Plugin support

Who makes the cut? Is it you?

Grasshopper import

Import existing work (if you promise not to complain I'm using different plugin versions than you)
