CadPeek is a free browser platform for opening DWG/DXF without AutoCAD. View layers, search labels, measure distances, mark up issues, convert DWG↔DXF and CAD→PDF, and share view-only links. Built for contractors, engineers, owners, and reviewers. Local-first parsing by default, no install. Supports DWG R12–2024.

Hey Product Hunt 👋 I built CadPeek because CAD files still get emailed to people who can’t open them. Every week I see the same loop: a contractor sends a DWG shop drawing, the client has no AutoCAD, someone screenshots a PDF, and version chaos starts. AutoCAD is $250+/month per seat; “free viewers” often mean IT tickets and Windows-only installs. CadPeek is the fix I wanted in the field: Open DWG/DXF in Chrome/Safari — no plugin, no install 14 focused tools — each does one job (convert, analyze, measure, markup, PDF overlay, share link, etc.) Local-first — parsing runs in your browser unless you explicitly share a link Real workflows — measure on live geometry (not scaled PDFs), search device tags, batch-rename layers, export text to Excel, redline with arrows/notes and PNG export We’re especially useful for MEP, fire protection, and shop drawing review, but it works for general architectural plans too. Free to start — 50MB per file, no account required during launch. I’d love your feedback: What’s the first CAD pain you’d want solved in-browser? Would you use this on a tablet on site?

how does the local-first parsing actually work in the browser, is my dwg data getting uploaded anywhere or does it truly stay on my device?

Layer filter presets would be a huge time saver on big drawing sets, letting you save common combinations like "structural only" or "MEP + existing" and switch with one click instead of toggling each layer manually every time.

finally a way to peek at dwg files without bugging the cad guy for a pdf. layer search is faster than i expected on a big project file.
