Best CAD Software for Startups in 2026 (18 Tools Reviewed)

Startups need CAD tools that scale with the team, run in the browser (no IT department), have flexible per-seat pricing, and integrate with modern dev workflows (version control, REST APIs, webhooks). The 2026 landscape rewards cloud-native CAD (Onshape, Fusion 360, Shapr3D) and free/open-source options that don't require capex approval. Below are every CAD tool in our catalog with founder-friendly pricing: free, freemium, open-source, or subscription under $100/month.
