Browser CAD for 3D printing — install nothing, ship something.
ForgeSlicer is a free, full-featured CAD tool that runs entirely in your browser. Primitives, Booleans, parametric editing, AI mesh generation, voice commands and slicing — no download, no Fusion 360 license, no waiting for an installer.
Open the URL, start designing. Works on Mac, Windows, Linux, Chromebook. Your designs save locally; you can sign in to publish them.
Primitives, parametric Booleans, edge fillets, 2D sketches, sweep extrusion, texture / glyph primitives, mesh import (STL/OBJ/3MF), Reverse-Engineer (RANSAC primitive fitting on imported scans).
Speak edits as if you were briefing a colleague. “Add a 5 mm keyring hole.” “Make this hollow with 2 mm walls.” Faster than menu hunting.
Built-in JS slicer, server-side OrcaSlicer engine, or export to your desktop slicer. The entire design → G-code pipeline lives in your tab.
