About LlamaIndex
A data framework for building LLM applications with your own data in TypeScript.
LlamaIndex is a framework that lets developers connect their own data sources to large language models like OpenAI, Anthropic, Gemini, and others. It handles data ingestion, indexing, and querying so applications can retrieve and reason over custom data. It targets TypeScript developers building LLM-powered apps across Node.js, Deno, Bun, Vercel Edge, and Cloudflare Workers.
Where to start
Install the core package and the relevant provider package for your chosen LLM (for example, @llamaindex/openai for OpenAI), then follow the getting started guide in the official documentation at ts.llamaindex.ai.
