echoOLlama leverages the Ollama ecosystem to provide a minimal agent framework: it reads user input from the terminal, sends it to a configured local LLM, and streams back responses in real time. Users can script sequences of interactions, chain prompts, and experiment with prompt engineering without modifying underlying model code. This makes echoOLlama ideal for testing conversational patterns, building simple command-driven tools, and handling iterative agent tasks while preserving data privacy.

Agents-Flex is a lightweight and elegant Java framework for Large Language Model (LLM) applications. It allows developers to define, parse and execute local methods efficiently. The framework supports local function definitions, parsing capabilities, callbacks through LLMs, and the execution of methods returning results. With minimal code, developers can harness the power of LLMs and integrate sophisticated functionalities into their applications.

Chatchat Lite is an open-source, lightweight chat UI framework designed to run in the browser and connect to multiple AI backends—including OpenAI, Azure, custom HTTP endpoints, and local language models. It provides real-time streaming responses, Markdown rendering, code block formatting, theme toggles, and persistent conversation history. Developers can extend it with custom plugins, environment-based configurations, and adaptability for self-hosted or third-party AI services, making it ideal for prototypes, demos, and production chat apps.

Cyrano is an open-source Python framework and CLI for creating AI agents that orchestrate large language models and external tools through natural language prompts. Users can define custom tools (functions), configure memory and token limits, and handle callbacks. Cyrano handles parsing JSON responses from LLMs and executes specified tools in sequence. It emphasizes simplicity, modularity, and zero external dependencies, enabling developers to prototype chatbots, build automated workflows, and integrate AI capabilities into applications quickly.

llama-cpp-agent is an open-source C++ framework for running AI agents entirely offline. It leverages the llama.cpp inference engine to provide fast, low-latency interactions and supports a modular plugin system, configurable memory, and task execution. Developers can integrate custom tools, switch between different local LLM models, and build privacy-focused conversational assistants without external dependencies.

multiagent-golang provides a structured approach to building multi-agent systems in Go. It introduces an Agent abstraction where each agent can be equipped with various sensors to perceive its environment and actuators to take actions. Agents run concurrently using Go routines and communicate through dedicated messaging channels. The framework also includes an environment simulation layer to handle events, manage the agent lifecycle, and track state changes. Developers can easily extend or customize agent behaviors, configure simulation parameters, and integrate additional modules for logging or analytics. It streamlines the creation of scalable, concurrent simulations for research and prototyping.
