Aircad

Key facts: Aircad launched on Hacker News on November 10, 2026. It is precision 2D drafting and 3D modeling in the browser, with multiplayer editing and an AI agent that drafts, models and renders alongside you: ask a question or describe an edit in plain words and the agent works right in your drawing. It opens your DWGs with their layouts, blocks and dimensions, with a command line that takes the shortcuts you already know, NURBS-based solid modeling, and built-in block libraries for doors, windows, furniture and plumbing in Imperial and Metric. No installs: open a browser and start drawing, always on the latest version.

Plans: Free $0 forever: 3 personal files, 3 DWG or DXF conversions a month, real-time collaboration and reviews, 30 days of version history, scripting and commands, and 200 AI credits to start. Pro $29 a month, or $19 a month in the Founder's Club for new accounts until January 31, 2027, kept for as long as you stay subscribed: unlimited files, unlimited DWG and DXF import and export, full version history, and a monthly AI allowance.

Best for: Architects, engineers and designers who want pro drafting without installing heavy desktop CAD. Who should skip it: anyone deep in AutoCAD's plugin ecosystem, or who needs offline desktop CAD.
