WebDev
Runnable frontend products paired with natural-language briefs, development trajectories and expert evaluation of aesthetics, motion and interaction.
Overview
Copula WebDev provides training and evaluation data for frontend aesthetics and complex interaction. Each task begins with a natural-language brief. A coding agent builds, renders and iterates through multiple steps to produce a runnable frontend project, accompanied by finished screenshots, development trajectories and expert-authored dimensional scores.
The data focuses on visual quality, motion and gestures, multi-step interaction flows, and how well the design fits its intended use. Samples are organized across industries, product formats, page types and visual styles. Task-specific criteria assess functional behavior and design quality, supporting frontend generation training, preference comparisons between implementations of the same brief, and capability evaluation.
