web4kit is a toolkit for building web pages that dynamically adapt their content, layout, and components per visitor using System One decision models (like Jev) instead of LLMs. It moves page planning from build time to request time, selecting from pre-defined manifests based on context signals, and renders deterministically with fail-soft behavior. The approach is novel and well-engineered, with a focus on safety, cost, and explainability.

Target audience: frontend developers, full-stack developers, web engineers interested in personalization
