Zoo Design Studio is a cross-platform CAD application (Electron desktop builds plus a browser build) where every model is plain-text KCL code that can be diffed and version-controlled, editable through both point-and-click tools and a built-in code editor. Its 3D viewport streams video from Zoo's cloud-hosted GPU geometry engine over WebSockets, and it embeds Zookeeper, an AI CAD agent, alongside sketching, constraints, and file-conversion features.

Use cases

• design 3d cad models by writing code instead of clicking
• version control my cad models in git like source code
• open source alternative to solidworks or fusion 360
• generate 3d models from text prompts with an ai agent
• point-and-click sketching with dimensions and constraints
• build parametric or generative parts for hardware design
• convert between cad file formats

When to choose

• You want code-first CAD where models are human-readable text checked into git
• You want a hybrid workflow switching between GUI point-and-click and hand-written KCL on the same project
• Your local machine struggles with heavy geometry rendering and you accept a cloud engine streaming the view
• You want AI assistance (Zookeeper agent, MCP tools) built into your modeling workflow

When to avoid

• You need fully offline CAD — the 3D view and geometry operations depend on Zoo's hosted engine and an account
• You rely on legacy proprietary CAD interoperability, large assemblies, or mature 2D drawing/drafting output
• You want a self-contained tool with no cloud dependency or usage-based pricing for engine time
