Live preview development environment for web projects, from static HTML to fullstack applications. \n \n Supports React, Vue, Vite, static HTML, Express, FastAPI, Streamlit, and Gradio with automatic health checking and error diagnostics \n Handles fullstack projects by building frontend and serving both API and static files from a single backend port \n Includes community publish feature to generate permanent public URLs for sharing previews on the internet \n Requires relative paths for all as

Analyze competitor keywords to build a prioritized content and optimization roadmap. \n \n Identifies keyword overlap across 3-5 competitors, categorizing terms into battleground positions, content gaps, and white-space opportunities \n Scores gaps using volume, winnability, and business value to prioritize quick wins, new content creation, and long-term authority plays \n Generates competitive battlecards documenting each competitor's strengths, weaknesses, and differentiation points for ongoin

PufferLib is a high-performance reinforcement learning library designed for fast parallel environment simulation and training. It achieves training at millions of steps per second through optimized vectorization, native multi-agent support, and efficient PPO implementation (PuffeRL). The library provides the Ocean suite of 20+ environments and seamless integration with Gymnasium, PettingZoo, and specialized RL frameworks.
