Kelp is a free, browser-based parametric design tool for generative structures — model
panels, lattices, waffles, surfaces, blobs, and branching forms, then export
fabrication-ready DXF, STL, and OBJ files for CNC/ laser cutting and 3D printing.
About Kelp
Kelp is a free, browser-based parametric design tool for generative structures. Model in
3D, adjust parameters in real time, and export fabrication-ready geometry as DXF, STL,
and OBJ for CNC routing, laser cutting, and 3D printing — no install, no complex node
libraries or nested menus.
An expanding suite of elementary workspaces
Each workspace is built around one kind of structure — not a general-purpose CAD
environment. Pick a workspace, tune a few controls, and see the form update instantly.
- Panel — flat paneled skins and frames
- Cell — modular lattice structures
- Rib — slotted waffle assemblies
- Field — carved and sculpted surfaces
- Blob — layered organic forms
- Branch — branching, tree-like structures
Simple by design
- Instant parameter control — sliders and inputs, not node graphs or scripting
- No complex UI — no Grasshopper-style wires or nested tool palettes
- Automation over manual drafting — geometry is generated and updated for you
- Little to no learning curve — open a workspace and start shaping immediately
Works in the browser — including on mobile
Kelp runs entirely in the browser on phones, tablets, and desktop — no app store, no
plugins. Sketch on a tablet, review on your phone, export from any device.
Fabrication-ready geometry
- DXF for 2D CNC and laser workflows
- STL and OBJ for 3D printing and CAM
- Unit-aware controls (metric and imperial) from design through cut file
Who it's for
- Makers and fabricators prototyping cut-ready layouts
- Students and educators exploring parametric structure without heavy software

Designers and architects iterating on generative form before detailed documentation
Kelp is in beta — workspaces and export paths are actively improving.
