Agent Based Modeling Python Packages

mesa

Mesa is an open-source Python library for agent-based modeling, ideal for simulating complex systems and exploring emergent behaviors.

bptk-py

System Dynamics and Agent-based Modeling in Python

tradefloor

A simulated stock market for testing trading strategies and AI agents. Orders move prices, any market can be forked, and every run reproduces exactly.

agentsociety

AgentSociety 2 is a modern, LLM-native agent simulation platform designed for social science research and experimental design. It provides a flexible framework for creating and managing intelligent agents in simulated environments.

doces

DOCES (Dynamical Opinion Clusters Exploration Suite) is an experimental Python library to simulate opinion dynamics on adaptive complex networks. Its background is implemented in C for performance.

citybehavex

CityBehavEx is a scalable, empirically validated, LLM-assisted urban behavior simulation platform. It generates synthetic city-scale mobility trajectories and lets users inspect, replay, debug, and evaluate them against observed mobility, time-use, semantic, transport, and social-network patterns.

starsim

Starsim disease modeling framework

aasm

Just in time and ahead of time

bourse

Rust Market Simulation Library with a Python API

agentsociety2

AgentSociety 2 is a modern, LLM-native agent simulation platform designed for social science research and experimental design. It provides a flexible framework for creating and managing intelligent agents in simulated environments.

AgentPy is an open-source framework for the development and analysis of agent-based models in Python.

agentmet4fof

Metrological Agent-based system (MET4FOF project)

pretium

A simulated stock market for testing trading strategies and AI agents. Orders move prices, any market can be forked, and every run reproduces exactly.

rasad-sim

Measure how much of a stochastic simulation's result is a property of the model and how much is the random seed.

kegal

Kedos Graph Agent for LLM

bamengine

High-performance Python framework for the BAM agent-based macroeconomic model using ECS architecture and vectorized NumPy operations

macrostat

A Package providing multiple tools for the statistical analysis and treatment of macroeconomic simulation models, with a particular focus on Agent-based and Stock-Flow Consistent Models

mesa-llm

Extension to the Mesa repository to provide with the ability to plug LLM directly into your agents for more complex reasoning and inter-agent communication ! Make your own reasoning/memory/communication modules and plug them into the existing code or use the pre-built ones for fast building.⁦
