OpenCUA Website

This repository contains the source for the OpenCUA website, including the landing page, interactive trajectory viewer, and supporting assets.

Getting Started

Serve the repository root with Python's built-in HTTP server and open http://localhost:8000 in your browser:

python3 -m http.server 8000

If you edit any task data under static/trajs/<task_id>/, regenerate the aggregated trajectory file before reloading the page:

python3 convert_task.py
