Lobe Chat – what is it?

Lobe Chat is an open-source web interface for interacting with large language models, providing users with convenient browser-based access to AI with support for both local and cloud backends. Architecturally, Lobe Chat is designed for integration with model APIs (including OpenAI and other providers) and also supports local deployments, enabling control over data, model configuration, and the execution environment without vendor lock-in.

In practical scenarios, Lobe Chat is used to build personal and enterprise AI assistants, test models, work with prompts, and enable multi-session interaction with LLMs. The interface supports extensions, model behavior customization, integration with RAG systems, and context persistence, allowing it to function as a lightweight frontend for internal AI services, solution prototyping, and collaborative workflows with models.
