Paprika3D lets coding agents inspect Three.js scenes
A Three.js MCP server and Claude Code plugin for screenshotting, testing, inspecting, and profiling 3D pages built with Three.js, React Three Fiber, or WebGL.
- For
- Three.js developers using coding agents
- Worth noticing
- Its repeatable test loop advances a paused, seeded clock in 1/60-second frames, making the same inputs produce the same frames and state.
Field notes
The documentation describes a mini-golf test where an agent was asked to scale a car to 0.8; the inspection output instead reports the car at 0.0338 units on an eight-metre course. The site also reports fewer wrong-scale or missing imported models in its comparison with paprika3D than with an agent alone, across 11 runs in each case. That result is attributed to tests with Sonnet 5.5 on clean installs, rather than independently verified here.
