PolicyArena.dev
LivegenaiAgent-Based Simulation Engine
PolicyArena is an open-source simulation engine that lets you pit rule-based, reinforcement learning, and LLM-powered agents against each other in game-theoretic environments. It features live-streamed simulations with real-time visualization, per-agent analytics dashboards, multi-run statistical comparisons, and full data export capabilities. Available on PyPI via pip install policy-arena, it provides a unified interface across five major LLM providers. The plugin architecture makes it straightforward to define custom agent behaviors and new game scenarios.

Problem
Researchers and developers studying multi-agent systems lacked a unified platform to compare different agent architectures (rule-based, RL, LLM) under controlled game-theoretic conditions. Existing tools were either too academic (no visualization) or too narrow (single agent type).
Approach
Built an event-driven simulation engine in Python with a plugin architecture allowing any agent type to be registered. Added real-time WebSocket streaming so simulations can be watched live. Created a React frontend with D3.js for interactive visualization of agent behaviors, payoffs, and strategy evolution across runs.
Architecture
Event-driven simulation engine with a Python backend serving WebSocket connections for real-time streaming. React frontend with D3.js visualizations renders live agent interactions and analytics dashboards. Plugin architecture allows custom agent types (rule-based, RL, LLM) with a unified interface across 5+ LLM providers. Simulation state is managed server-side with event sourcing for replay capability.
Results
Published as open-source on PyPI with 15+ built-in game scenarios. Supports OpenAI, Anthropic, Gemini, DeepSeek, and Ollama as LLM backends. Used for research comparisons and educational demonstrations of game theory concepts.

TripGen.org
LivegenaiAgentic AI Travel Planner
TripGen is an agentic AI travel planner that orchestrates 10+ specialized agents running in parallel to generate comprehensive trip itineraries. Each agent handles a specific aspect — flights, hotels, activities, dining, logistics — coordinated through MCP tool integration. The conversational chat interface allows users to refine plans iteratively, while the system generates day-by-day itineraries with activities, photos, interactive maps, and estimated budgets. Built with observability-first design using Langfuse for full agent trace visibility.

Problem
Travel planning involves coordinating dozens of decisions across flights, accommodations, activities, dining, and logistics. Existing AI travel tools either produced generic suggestions or couldn't handle the complexity of multi-day, multi-city itineraries with real constraints like budgets and preferences.
Approach
Designed a multi-agent system where specialized agents each own a domain (flights, hotels, activities, dining). Agents run in parallel via async Python and coordinate through a central orchestrator. MCP tool integration enables agents to query real services. A conversational interface lets users iteratively refine the plan.
Architecture
Multi-agent orchestration system where 10+ specialized agents run in parallel via async Python. FastAPI backend on GCP Cloud Run handles agent coordination and MCP tool integration for external service calls. React frontend provides conversational chat with streaming responses, interactive map rendering via Google Maps API, and itinerary visualization. Langfuse integration provides full observability into agent decisions and tool usage.
Results
Generates complete day-by-day itineraries with activities, photos, maps, and budgets. Conversational refinement allows natural back-and-forth. Full agent observability through Langfuse traces every decision and tool call.
Tech Stack
Highlights
- 10+ parallelized AI agents with domain specialization
- MCP tool integration for external service calls
- Conversational chat interface with streaming responses
- Day-by-day itineraries with activities, photos, and maps

Problem
People relocating to a new city struggle to evaluate neighborhoods objectively. Information is scattered across forums, real estate sites, and local knowledge. There was no tool that scored neighborhoods across multiple lifestyle dimensions with a consistent methodology worldwide.
Approach
Built an AI scoring pipeline that aggregates data from multiple sources and applies weighted scoring across dimensions (safety, affordability, commute, lifestyle). Created interactive maps with filterable overlays so users can visually explore results. Added SEO-optimized city pages to capture organic search traffic from people researching relocations.
