Premium support or additional services may be offered by its sponsor Stream. - **Requirements:** Developers must have familiarity with React and TypeScript to leverage llm-ui effectively.; The library includes integration support for Shiki, so installations or configurations of related dependencies may be required. - **Adopt for:** llm-ui is a React library developed in TypeScript that focuses on creating user interfaces for large language models, it includes features such as throttling of streamed output and support for custom component rendering. - **License detail:** llm-ui is released under the MIT license, allowing for free use and modification in both open source and commercial projects. ## Choose when ### Choose agent-prism if… - Tags unique to agent-prism: ai-agents, ai-monitoring, distributed-tracing, langchain. - Also covers AI Agents, Evaluation & Observability. - If your project uses TypeScript and React for front-end development, and you need to monitor AI agent behavior effectively without reinventing the UI wheel. ### Choose llm-ui if… - Pricing: The core library of llm-ui is available free-of-charge with no license fee. Premium support or additional services may be offered by its sponsor Stream.. - Requirements: Developers must have familiarity with React and TypeScript to leverage llm-ui effectively.; The library includes integration support for Shiki, so installations or configurations of related dependencies may be required.. - Tags unique to llm-ui: chatgpt, claude, llama, markdown. - Also covers LLM Frameworks. - Use llm-ui if you are specifically working with React applications and require an optimized UI experience for integrating with LLMs through smooth streaming and custom components. ## When NOT to use agent-prism - Consider other options if your project does not use TypeScript since adapting libraries specifically tailored for TypeScript might introduce unnecessary complexity. - If real-time dynamic updates are critical and the current data handling mechanisms of agent-prism do not meet these requirements, look elsewhere. ## When NOT to use llm-ui - Avoid llm-ui if your development environment is not based on React or TypeScript, as this tool is not suitable for other frontend frameworks. - Do not use llm-ui if seamless integration with external styling libraries is not a priority, since its headless approach requires manual styling efforts. ## Common questions ### What is the difference between agent-prism and llm-ui? agent-prism: React components for visualizing traces from AI agents. llm-ui: The React library for LLMs. See the comparison table for live GitHub stats and shared categories. ### When should I choose agent-prism over llm-ui?
