LobeChat Database Version

LobeChat is an open-source, high-performance chatbot framework that offers flexibility in its database setup.

By default, LobeChat utilizes a client-side database (IndexedDB) for data storage. However, for users requiring more robust data management or scalability, LobeChat also supports deploying a server-side database solution.

In this server-side configuration, LobeChat leverages PostgreSQL as its backend storage database. PostgreSQL is a powerful, open-source object-relational database system with over 30 years of active development. It has earned a strong reputation for reliability, feature robustness, and performance.

This comprehensive guide will walk you through the process and principles of deploying the server-side database version of LobeChat on Zeabur, a modern cloud platform designed for easy deployment and scaling of web applications.
