Open Source AI Platform - AI Chat with advanced features that works with every LLM

Framework to build resilient language agents as graphs.

LangChain4j is an idiomatic, open-source Java library for building LLM-powered applications on the JVM. It offers a unified API over popular LLM providers and vector stores, and makes implementing tool calling (including MCP support), agents and RAG easy. It integrates seamlessly with enterprise Java frameworks like Quarkus and Spring Boot.

Mastra is the modern TypeScript framework for AI-powered applications and agents.
