WebCoder: Scaling General Frontend Development with Artifact-Grounded Agentic Reinforcement Learning

Key points

• Real-world frontend development requires agents to compose reproduction, generation, modification, and repair over an evolving application state.1
• Learning a general policy for this process requires translating heterogeneous execution feedback into task-aligned rewards and effective credit assignment across long sequences of interdependent actions.1
• We build Webdev-World, an executable environment that integrates code editing, application execution, browser inspection, and on-demand skills while preserving project state across interactions.1
• We further introduce Webdev-Bench to evaluate composed development requirements within a single project.1
