Free AutoCAD Alternative — Online 2D CAD & DWG Drafting
A complete AutoCAD-style 2D drafting tool that runs entirely in your browser: precision snapping, layers, blocks, dimensions, and real DWG and DXF files. Nothing is uploaded — your drawings stay on your own device.
CADCraft
AutoCAD-style 2D drafting — DWG and DXF, precision snapping, and dimensions — in your browser.
First launch downloads ≈9 MB, then it's cached for a year. Nothing is uploaded — your files stay on this device.
This is a desktop-class app — it works best on a larger screen.
Quick Answer
This free online CAD tool gives you the core AutoCAD 2D workflow in a browser tab: precision line, arc, and polyline drawing with object snaps and ortho tracking, layers, blocks and references, hatching, linear and angular dimensions, and paper-space layouts for plotting. It opens and saves real DWG and DXF files that round-trip with desktop CAD packages. The application is a Rust geometry kernel compiled to WebAssembly running on your device — drawings are never uploaded to any server.
How It Works
Open and Launch — Open the CAD drafting page in a desktop browser and click Launch. The first launch downloads about 9 MB; after that it is cached.
Open or Start a Drawing — Open an existing DWG or DXF through the file picker, or start a blank drawing with your units and limits.
Draw with Precision — Use snaps and ortho tracking for lines, polylines, arcs, and circles; organize with layers and insert blocks.
Dimension and Save — Add dimensions and annotations, set up a paper-space layout, and save as DWG or DXF to your device.

Frequently Asked Questions
Is this really free, and do I need an account?
Yes — completely free, no account, no watermarks. The underlying software is open source under Apache-2.0, embedded exactly as published.
Are my drawings uploaded anywhere?
No. The whole CAD application runs as WebAssembly inside your browser tab; drawing, editing, and saving all happen on your device through the browser file picker and downloads.
Does it work with real DWG files?
Yes — it opens DWG and DXF files with entities, layers, blocks, and dimensions intact, and saves files desktop CAD packages read. Very exotic entities or custom object enablers may fall back to proxy graphics, but everyday 2D drafting geometry round-trips cleanly.
How is this different from the FreeCAD CAD editor?
They cover different jobs. This one is AutoCAD-style 2D drafting — technical drawings, plans, and layouts in DWG/DXF. The FreeCAD editor is parametric 3D CAD — solid modeling, assemblies, and parts. Draft a floor plan here, model the machine part there.
Does it work on mobile?
It runs on modern mobile browsers, but precise drafting wants a desktop screen, a mouse with a scroll wheel for zoom/pan, and keyboard command entry. For viewing drawings on a phone, any DWG viewer works.
