LibreChat

What is LibreChat about?

LibreChat offers an open‑source, web‑based chat client that mimics the ChatGPT experience while allowing users to switch between a wide range of AI providers (OpenAI, Anthropic, AWS Bedrock, Azure OpenAI, Google Vertex, DeepSeek, Mistral, Groq, etc.). It extends the core chat experience with no‑code agents, a sandboxed code interpreter, image generation/editing, web search, multilingual UI, and advanced context management.

How to use LibreChat?

1. Deploy – Choose a deployment method that fits your environment:
   • Docker Compose: docker compose up -d
   • One‑click cloud: Deploy via Railway, Zeabur, or Sealos using the provided buttons.
   • Local development: Clone the repo, run npm install then npm run dev (or npx serve after a build).
2. Configure AI endpoints – Edit librechat.yaml (or use the UI settings) to add API keys for the desired providers. Custom OpenAI‑compatible endpoints are supported without a proxy.
3. Create users – Enable OAuth2, LDAP, or email login for secure multi‑user access.
4. Start chatting – Select a model or preset, optionally enable an agent or tool, and begin interacting.

FAQ from LibreChat

Q: Do I need an OpenAI account to run LibreChat? A: No. You can use any configured endpoint, including local models via Ollama or self‑hosted MCP servers.

Q: How is my data protected? A: The code interpreter runs in isolated sandboxes; all user data stays on your server unless you configure external services.

Q: Can I add my own tool or plugin? A: Yes. LibreChat supports custom MCP tools; define them in the tools section of the configuration and reference them in agents.

Q: What deployment options are recommended for production? A: Docker Compose behind a reverse proxy (NGINX/Traefik) with HTTPS, and enable OAuth2 or LDAP for authentication.

Q: Is there a cloud‑hosted version? A: The repository provides one‑click deploy buttons for Railway, Zeabur, and Sealos, but the service remains open‑source and can be self‑hosted.
