Comparison
Open 2D Studio is an open source 2D CAD tool built with Rust and Tauri. Compare to AutoCAD LT on features, pricing, platforms and license model.
AutoCAD LT is the streamlined 2D version of Autodesk's iconic AutoCAD, first released in 1993. It's the de facto standard for 2D drafting in architecture, civil engineering and building services, with a deep ecosystem of plug-ins, families and exchange formats. AutoCAD LT typically costs €500-700 per user per year (subscription, annual or multi-year).
Open 2D Studio from the OpenAEC Foundation is an open source 2D CAD application (current version v0.35, 90+ commits, 17 stars on GitHub). Built with Rust and Tauri for speed and a low memory footprint, cross-platform on Windows, macOS and Linux. Supports line, arc, circle, polyline, hatch, layers, dimensions and DXF exchange.
