LibreChat

What is LibreChat about?

LibreChat delivers an all‑in‑one conversational interface that lets users chat with a wide range of AI providers (OpenAI, Anthropic, AWS Bedrock, Azure, Google Vertex, Groq, Mistral, DeepSeek, OpenRouter, etc.) while supporting custom OpenAI‑compatible endpoints. It adds advanced tooling such as no‑code agents, a sandboxed code interpreter, image generation/editing, web search, speech‑to‑text/text‑to‑speech, and powerful context management features.

How to use LibreChat?

1. Deploy – Choose a deployment option (Docker, Railway, Zeabur, Sealos, or local npm/yarn install). Follow the quick‑start guide to set environment variables for the desired AI endpoints.
2. Configure – Edit the librechat.yaml (or .env) to add API keys, enable/disable providers, and customize UI presets.
3. Access – Open the web UI, log in via OAuth2, LDAP, or email, and start new conversations.
4. Select Model – Switch between AI models or presets on the fly using the dropdown menu.
5. Leverage Tools – Activate agents, run code snippets, generate images, or perform web searches directly from the chat input.

FAQ from the LibreChat

Q: Do I need a proxy to use OpenAI or Anthropic? A: No. LibreChat can call any OpenAI‑compatible endpoint directly, eliminating the need for a proxy.

Q: Can I run LibreChat completely offline? A: Yes, by pointing the configuration to local LLMs (e.g., Ollama, Mistral, or other MCP servers) and disabling external providers.

Q: How is code execution sandboxed? A: The interpreter runs in isolated containers with network and filesystem restrictions, ensuring no leakage of user data.

Q: What deployment options are available? A: Docker, Railway, Zeabur, Sealos, or manual Node.js installation. All options are documented in the quick‑start guide.

Q: Is there a way to limit token usage per user? A: Built‑in token spend monitoring lets admins set quotas and view usage per account.
