Open WebUI vs LibreChat vs AnythingLLM: Choose Your Self-Hosted AI Interface
Three powerful open-source LLM platforms solve different problems. Find the fit for your team in under 5 minutes.
Quick Decision Matrix: Which Tool Solves Your Problem?
| Your workflow | Best choice | Why |
|---|---|---|
| Running local Ollama models | Open WebUI | Built for Ollama. Includes RAG with 9 vector databases. 18,717 commits. Most feature-rich. |
| Switching between OpenAI, Claude, Groq, Azure, AWS | LibreChat | Acts as command center for multiple AI providers. 56.4M Docker pulls. Supports agents and MCP. Acquired by ClickHouse (Nov 2025). |
| Document chat with strict privacy | AnythingLLM | Workspace-based isolation. Desktop app + server. No account required. 5M+ Docker pulls. Runs completely on your device. |
Each solves a distinct problem. You're not picking the "best"—you're picking the best fit for how you work.

What Each Platform Does Best
Open WebUI: Ollama's Best Friend
Built for teams running local language models via Ollama. If you're keeping AI entirely on-premise and don't need multi-provider switching, this is the fastest path forward. Features include persistent memory, channels for team collaboration, a built-in terminal, image generation, web search, and file storage.
RAG implementation is mature: 9 vector database backends (ChromaDB, PGVector, Qdrant, Milvus, Elasticsearch, Pinecone, OpenSearch, S3Vector, Oracle 23ai). This matters for knowledge-heavy workflows where you chat with your own documents.
Trade-off: Requires BSD-3 license attribution—you cannot rebrand it without keeping "Open WebUI" visible.
LibreChat: The Provider Switcher
Designed for teams evaluating multiple LLM providers simultaneously. Supports OpenAI, Anthropic Claude, Azure OpenAI, AWS Bedrock, Groq, Mistral, Ollama, and custom endpoints. You add your own API keys and switch between models in the same conversation.
Advanced features: Agents for multi-step reasoning, Model Context Protocol (MCP) support, and Code Interpreter that executes Python, Node.js, Go, C/C++, Java, PHP, and Rust in sandboxed environments. Acts as a proxy layer, not a local model runner.
Recent acquisition by ClickHouse (November 2025) signals a data-centric future—likely heading toward better logging, analytics, and data export.
Scale indicator: 56.4M Docker pulls, suggesting broad enterprise adoption.
AnythingLLM: The Privacy-First Document Platform
Built around workspace isolation. Each workspace keeps documents, chats, and settings separate. Designed for privacy: no account required (runs entirely on your device), no API calls unless you choose to enable an LLM provider, and sensitive documents stay local.
Meets specific workflows: Meeting Assistant (auto-transcription + summarization), desktop apps for Mac/Windows/Linux, and vector DB support for RAG (Qdrant, Pinecone, Chroma, and others). Workspace model means teams can run multiple isolated projects without documents leaking between them.
Trade-off: Less feature-rich on authentication (no LDAP or OAuth). Better for small teams prioritizing privacy over enterprise integrations.
Why These Choices Matter
Picking between them is about answering one question: What does your workflow require?
- Ollama purist: Open WebUI.
- Multi-cloud shopper: LibreChat.
- Privacy-first document handler: AnythingLLM.
Each excels in its lane. Switching between them costs weeks of work (data export, user re-setup, new model configurations).
The Hidden Cost of Self-Hosting Any of Them
All three are free to download. The actual cost lives elsewhere:
- Server infrastructure: EUR 50-500/month for compute, depending on model size and concurrency
- Database management: Redis, PostgreSQL, vector DBs—monitoring, backups, scaling
- Team onboarding: Each person needs deployment docs, API credentials, and troubleshooting help
- Updates: Security patches, dependency upgrades, version compatibility testing
- Monitoring: Alerting for crashes, disk space, failed jobs
- Backups: Encrypted, isolated, tested recovery (not optional)
These aren't trivial. A solo developer might absorb them. A 20-person company usually can't.

Questions About Open WebUI, LibreChat, and AnythingLLM
If you're running Ollama locally and want a user-friendly chat interface with built-in RAG, Open WebUI is the natural choice. It has 18,717 commits (most developed), 154.1K GitHub stars, and 9 vector database options. LibreChat and AnythingLLM both support Ollama, but they're optimized for different workflows: LibreChat for multi-provider switching, AnythingLLM for document isolation. Try Open WebUI first—it's the tightest integration with Ollama.
