Big-AGI vs LibreChat

Big-AGI

• People with API keys for several providers who compare answers
• Checking an important answer across models before acting on it
• Self-hosters and IT teams that want an MIT-licensed chat interface

LibreChat

• Teams that want a self-hosted chat interface they can audit and extend
• Organizations that need SSO and control over where chat data lives
• Using API keys from several model providers in one place

Big-AGI

• No model access is included: every tier needs your own API keys, and each provider bills usage directly.
• Cloud backup and multi-device sync are Pro features. On Free and Open, chats stay in the browser on one device.
• It runs in the browser and installs as a web app; the site lists no native desktop or mobile apps.
• Team management and SLA guarantees are offered only through a custom Business plan with no public price.

LibreChat

• It is a self-hosted web application: the docs say there is no native Windows app or Linux AppImage, and no hosted paid plan is offered.
• You run it yourself with Docker, npm or a Helm chart and supply your own model API keys.
• The public demo at chat.librechat.ai is for evaluation only and is not meant for private data.
• The code interpreter, message search and file chat rely on extra services you deploy: a code-execution service, Meilisearch and the RAG API.

Big-AGI

Beam and Merge

Beam sends one prompt to between 2 and 24 models in parallel, each answering without seeing the others. Merge then fuses the replies into one answer with built-in or custom merge prompts.

Your own keys for 30+ services

Connects directly to OpenAI, Anthropic, Google Gemini, Mistral, DeepSeek, OpenRouter, Azure and AWS Bedrock, and to local servers such as Ollama and LM Studio, with no markup on usage.

Precise model controls

Effort, temperature, verbosity, reasoning budget, search and tools can be set per request or per persona across more than 800 models.

Personas

A persona carries its own instructions, attached documents and images, memory, a fixed model with parameters, and a voice, so a role can be reused across chats.

AI Inspector

Shows the exact request leaving the browser, including the model, parameters, tokens and cost, both before and after it runs.

Local-first with optional sync

Chats and settings stay in the browser by default. Pro adds cloud backup and sync of chats and personas across devices.

LibreChat

Many providers in one interface

Works with OpenAI, Anthropic, Google, Azure and AWS Bedrock out of the box, and custom endpoints add Ollama, Mistral AI, OpenRouter and other services.

Agents

Build custom assistants with tools, file handling, code execution and API actions without writing code.

Code Interpreter

Runs Python, JavaScript, Go, Rust and other languages in a sandbox. It is powered by an Apache 2.0 code-execution service that you deploy and point LibreChat at.

MCP and web search

Connects models to external tools through Model Context Protocol servers and gives any model live internet access with built-in search and reranking.

Artifacts and chat tools

Generates React components, HTML pages and Mermaid diagrams in chat, and supports forking, shareable links, temporary chats and importing conversations from ChatGPT.

Multi-user authentication

Sign-in through OAuth2, SAML or LDAP with two-factor authentication, plus an admin panel for users, roles and configuration, and moderation tools.
