FreeChat provides a cloud-native platform for creating and managing AI virtual characters, targeting enterprise-level applications and prompt engineering. It offers robust features for character customization, multi-backend support, and extensive API access, enabling developers to build sophisticated AI-driven systems.

How It Works

Built primarily with Java and Spring Boot, FreeChat emphasizes security, scalability, and maintainability. It employs distributed technologies and caching for high concurrency. Key features include a comprehensive account and permission system with OAuth2 support, an "organization" concept for access control, and flexible character configuration allowing multiple backends per character. This modular approach facilitates cost optimization and tailored user experiences.
