What OpenCAD is

OpenCAD is a browser-based 2D CAD editor for engineers, offered on the web and as self-hosted software. It provides 39 drawing and editing tools, including LINE, CIRCLE, ARC, POLYLINE, HATCH, DIMENSION, TRIM, OFFSET, FILLET, and ARRAY. AutoCAD DXF files can be imported and exported with roundtrip support while preserving 24 entity types. Layer controls cover visibility, locking, colors, linetypes, and isolation. OpenCAD is described as open source under the MIT License and self-hostable. The listed OpenCAD plan costs $5 a month, with the first 30 days free and no credit card required. CivilAL modules for progress billing, quantity surveying, earned value, and cost analysis can run separately or alongside OpenCAD. The site says it is built with React, TypeScript, Three.js, and FastAPI.

Who it suits

It suits engineers needing browser-based 2D drafting with DXF exchange and self-hosting. Civil engineers may also use the separately described CivilAL modules.

What it does well

  • 39 drawing and editing tools
  • DXF roundtrip support preserving 24 entity types
  • MIT-licensed and self-hostable
  • Layer visibility, locks, colors, and isolation
  • 30-day trial without a credit card

What to know first

Verdict

OpenCAD combines a broad 2D toolset with DXF roundtripping, layer controls, and self-hosting. Buyers needing native DWG should note that DWG export uses ODA File Converter instead.
