Show HN: CADara - I made an open-source in-browser CAD

· open-source · Source ↗

CADara is a new open-source, browser-native CAD tool built on OpenCascade 7.9 via WASM, targeting the full parametric modeling workflow without any install.

What Matters

  • Runs entirely in-browser using OpenCascade 7.9 compiled to WASM—no server-side geometry kernel.
  • Sketch solver written from scratch in TypeScript; builder calls it “substantially faster than I thought it would be.”
  • Current pre-alpha supports standard parametric CAD operations; mesh and curved-face manipulation are explicitly not yet included.
  • [HN: @ttouch] Stable geometry base is the priority before adding mesh/curved-face features—deliberate sequencing, not an oversight.
