Foldnano
Integrated Design Environment ยท Open-source
The IDE for
DNA Nanostructures
Design, inspect, and export DNA origami entirely in your browser. Run python plugins and scripts directly to analyze and modify your designs. No installation, no account, your data stays on your machine.
No installation, no registration. Local-first.
Runs entirely in your browser; designs live in local storage and never leave your machine unless you push them.
Mix lattices and unlatticed regions
Square, honeycomb, and freeform regions coexist in a single scaffold.
Drop-in compatible with cadnano
Import and export classic cadnano .json designs without conversion.
Built-in 3D structure view
Inspect your design in 3D as you edit, with no export round-trip.
Edit programmatically with live 3D preview
Script against the live design in Python, right in the browser.
part = doc.active_part()
for vh in part.virtual_helices():
vh.extend(21)Git(hub)-integrated version control

Python-in-browser plugin system
Extend the editor with sandboxed Python plugins. No server required, no setup.
Built-in rigid-body simulation
Relax and optimize long bonds without leaving the editor.
Direct export for oxDNA and mrDNA
