Just Chat delivers a complete self-hosted chat interface for interacting with large language models. By inputting API keys for providers like OpenAI, Anthropic, or Hugging Face, users can start multi-turn conversations with memory support. The platform enables attachments, letting users upload documents for context-aware Q&A. Plugin integration allows external tool calls such as web search, calculations, or database queries. Developers can design custom prompt templates, control system messages, and switch between models seamlessly. The UI is built using React and Node.js, offering a responsive web experience on desktop and mobile. With its modular plugin system, users can add or remove features easily, tailoring Just Chat to customer support bots, research assistants, content generators, or educational tutors.

Nuzon-AI provides a Python-based agent framework that lets you define tasks, manage conversational memory, and extend capabilities via plugins. It supports integration with major LLMs (OpenAI, local models), enabling agents to perform web interactions, data analysis, and automated workflows. The architecture includes a skill registry, tool invocation system, and multi-agent orchestration layer, allowing you to compose agents for customer support, research assistance, and personal productivity. With configuration files, you can tailor each agent’s behavior, memory retention policy, and logging for debugging or audit purposes.

MCP Agent provides a robust foundation for building intelligent AI-driven assistants by offering modular components for integrating language models, custom tools, and data sources. Its core functionalities include dynamic tool invocation based on user intents, context-aware memory management for long-term conversations, and a flexible plugin system that simplifies extending capabilities. Developers can define pipelines to process inputs, trigger external APIs, and manage asynchronous workflows, all while maintaining transparent logs and metrics. With support for popular LLMs, configurable templates, and role-based access controls, MCP Agent streamlines the deployment of scalable, maintainable AI agents in production environments. Whether for customer support chatbots, RPA bots, or research assistants, MCP Agent accelerates development cycles and ensures consistent performance across use cases.

NaturalAgents is an open-source Python library designed to streamline the creation and deployment of LLM-powered agents. It provides modules for memory management, context tracking, and tool integration, allowing agents to store and recall information over long sessions. A hierarchical planner orchestrates multi-step reasoning and actions, while an extension system supports custom plugins and external API calls. Built-in logging and analytics enable developers to monitor agent performance and debug workflow issues. NaturalAgents also supports synchronous and asynchronous execution, making it flexible for both interactive use cases and automated pipelines.

Arenas is designed to streamline the development lifecycle of LLM-powered agents. Developers can define agent personas, integrate external APIs and tools as plugins, and compose multi-step workflows using a flexible DSL. The framework manages conversation memory, error handling, and logging, enabling robust RAG pipelines and multi-agent collaboration. With a command-line interface and REST API, teams can prototype agents locally and deploy them as microservices or containerized applications. Arenas supports popular LLM providers, offers monitoring dashboards, and includes built-in templates for common use cases. This flexible architecture reduces boilerplate code and accelerates time-to-market for AI-driven solutions across domains like customer engagement, research, and data processing.

autogen4j is a lightweight Java library designed to abstract the complexity of building autonomous AI agents. It offers core modules for planning, memory storage, and action execution, letting agents decompose high-level goals into sequential sub-tasks. The framework integrates with LLM providers (e.g., OpenAI, Anthropic) and allows registration of custom tools (HTTP clients, database connectors, file I/O). Developers define agents through a fluent DSL or annotations, quickly assembling pipelines for data enrichment, automated reporting, and conversational bots. An extensible plugin system ensures flexibility, enabling fine-tuned behaviors across diverse applications.
