Free tools.
A growing set of free, browser-based tools for architects: sketch, edit Archicad XML, browse add-ons and objects. No installation, and most need no account.
archiSketch
Sketch and annotate ideas on a quick canvas, then export to PNG. No install, no account.
OpenarchiXML
Bulk-edit Archicad attributes in the open project: docks inside Archicad via Tapir. Or edit an XML export in the browser.
OpenarchiRepo
Browse the full catalogue of Architools add-ons, with features, screenshots and compatibility.
OpenarchiKnowledge
A searchable knowledge base of guides and how-tos across the whole toolset.
OpenarchiObjects
A growing library of free Archicad objects to drop straight into your projects.
OpenarchiHub
People pushing Archicad somewhere new with AI, Tapir and custom add-ons. Community-submitted, hand-verified.
OpenFree tools are great. Paid ones are better.
Browse the catalogue of native add-ons for Archicad, Revit, and Rhino: built on the same ethos.
