Open Source, Actively Maintained Web Apps for LLMs 💬
Jump-start your LLM project by starting from an app, not a framework. This repository aggregates high-quality, functioning web applications for use cases including Chatbots, Natural Language Interfaces, Assistants, and Question Answering Systems. It compares projects along important dimensions for these use cases, to help you choose the right starting point for your application.
To ensure the utmost quality and usability, projects must adhere to the following criteria to be included:
- Licensed under Open Source terms 💸
- Actively Maintained, meaning updated within the past month or under active monitoring 🚨
The projects span a wide range of complexity, from straightforward API wrappers to production-ready systems with multi-source RAG backends, conversation logging, and authentication/user management. There should be something for almost every need.
