LibreChat

LibreChat is a self-hostable chat interface that connects to virtually every major AI provider from one place. Instead of juggling separate tabs for OpenAI, Anthropic, Google, and others, you get a single UI where you can switch models mid-conversation, compare responses, and manage everything under one login. It's built for teams and organizations that want control over their AI tooling without depending on a SaaS vendor.

The platform sits in the same space as Open WebUI and LobeChat, but LibreChat leans heavily into multi-user deployments. Admins can manage users, set spending limits, assign roles, and configure which models each user can access. That makes it practical for companies rolling out AI access across a team rather than just personal use.

Key capabilities include:

• Multi-provider support: Connect OpenAI, Azure OpenAI, Anthropic, Google Gemini, Mistral, and more, including local models via Ollama.
• Custom agents: Build agents with specific instructions, tools, and model configurations that persist across sessions.
• File handling: Upload images, PDFs, and documents directly into conversations for context-aware responses.
• Plugins and tools: Extend conversations with web search, code execution, and third-party integrations.
• Conversation branching: Fork any message to explore different directions without losing the original thread.
