Weblica: A Scalable and Reproducible Training Environment for Visual Web Agents

·2026.07.07 09:00

Key point

Weblica provides a reproducible and scalable environment for training visual web agents through HTTP caching and LLM-based synthesis.

Details

Because web environments are complex and constantly changing, it is difficult to scale training data for Visual Web Agents. Existing data collection methods are limited to supervised fine-tuning (SFT) via offline trajectories or a small number of simulation environments, which fail to sufficiently reflect the diversity of the web.

To address this, we propose the Weblica (Web Replica) framework. This framework leverages the following core techniques.

  • HTTP-level caching: Captures and reproduces stable visual states while preserving interactive behavior.
  • LLM-based environment synthesis: Dynamically generates environments to ensure data diversity.

Through this, Weblica helps researchers overcome the complexity of the web and train agents in a more reproducible and scalable environment.
