Kiln is an open-source engine and local tools that enable coding agents to build and revise 3D assets. Agents write JavaScript using Kiln's helpers, and Kiln provides rendered views and structural checks for review, supporting GLB export.

kiln sits in the Code Assistant category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Agent-driven 3D asset creation and revision using JavaScript.. A representative use case is Generating and customizing 3D props and machinery for applications.. The listed license is MIT. GitHub stars are currently 288. Relevant tags include 3D Asset Generation, Code Assistant.
