It provides a standard framework to develop interoperable components and connect; pick just-chat if just-chat is a Python framework for setting up an LLM-based AI agent using Docker or Podman for quick chat interactions. It supports customization and provides. [langchain](https://docs.langchain.com/langchain/) reports 142k GitHub stars, 24k forks, and 419 open issues, last pushed Jul 11, 2026. [just-chat](https://github.com/longevity-genie/just-chat) has 74 stars, 13 forks, and 2 open issues, last pushed Nov 22, 2025.

However, it might rely on paid services or premium models from external platforms like OpenAI. - **Adopt for:** LangChain is an open-source platform designed specifically for building agents and applications that leverage large language models (LLMs). It provides a standard framework to develop interoperable components and connect - **License detail:** MIT License, allowing free use for both personal and commercial purposes under its stipulated terms. ## Decision facts: just-chat - **Adopt for:** just-chat is a Python framework for setting up an LLM-based AI agent using Docker or Podman for quick chat interactions. It supports customization and provides detailed installation instructions. ## Choose when ### Choose langchain if… - License: langchain is MIT, just-chat is Apache-2.0. - Pricing: LangChain itself is open-source and free to use. However, it might rely on paid services or premium models from external platforms like OpenAI.. - Tags unique to langchain: agents, ai-agents, anthropic, chatgpt. - Also covers LLM Frameworks. - * When aiming to build complex AI-powered agents or applications requiring high-level capabilities like planning, subagent interaction, and file system operations. ### Choose just-chat if… - License: just-chat is Apache-2.0, langchain is MIT. - Tags unique to just-chat: chatbot, docker composition, llm-agent, podman support. - Also covers Developer Tools. - just-chat ships Docker support for self-hosted deployment. - When you need to quickly set up and interact with an LLM-based AI agent without extensive configuration. ## When NOT to use langchain - * When working on smaller, less complex projects where full-scale integration with sophisticated components is not necessary as LangChain's extensive features might introduce unnecessary complexity. - * If you are primarily focused on JavaScript or TypeScript development as the primary focus of LangChain is Python. Although there is a JS/TS equivalent (LangChain.js), it may not offer the same depth - * For projects requiring heavy customization at lower levels, where a more granular control over individual components is required rather than working with an integrated framework. ## When NOT to use just-chat - If your workflow does not support Docker or Podman, as these are the only supported deployment environments. - When you are using Ubuntu 22.04 with the default Podman version (v3), which requires manual installation since it is not fully compatible with just-chat's setup. ## Common questions ### What is the difference between langchain and just-chat? langchain: The agent engineering platform.. just-chat: Make your LLM agent and chat with it simple and fast!.
