Twigg is a true parametric, node-based CAD system with a real solid-modelling kernel — running right in your phone's browser. A breakthrough action-bar workflow lets you model as fast as you would on a computer.
Free to use. Runs in the browser — nothing to install.
A real solid-modelling kernel in your pocket — not a mesh toy. Exact B-rep geometry, fully parametric, running inside a mobile browser. Change a number and the whole model rebuilds, right there on the screen.
The action bar puts your whole workflow under one thumb — no menus, no hunting. Try it right here: swipe, tap and hold the bar below. It won't build anything — it just shows you what each move does.
Touch-first doesn't mean slower. Orbit, snap, pick faces and scrub values with your fingers — the whole flow is built so the phone keeps up with your hands. No compromise, no "lite" version.
Every part is a graph of nodes — Object, Assembly, Mirror, Array, Revolve, Tube, Boolean. Nothing is baked; everything stays editable end-to-end. Have a play: grab the cable between them and let go.
Send your work straight to the workshop. Export .STL for 3D printing and .STEP for CAD and manufacturing — exact solids in, clean manufacturable files out.
Twigg is free to use while it grows. A Pro tier is on the way for people who want to take it further — join the waitlist to get early access and help shape it.
Twigg is growing fast and shaped by the people who use it. Come hang out, share what you make, and help steer where it goes.
Open Twigg in your browser and make your first parametric part in minutes — real CAD, right in your pocket.
