Best for——
Pros
  • One clean interface for many providers and models (OpenAI, Claude, Gemini, Ollama local models and more)
  • Rich feature set: knowledge-base RAG over your files, plugins/MCP tools, voice input, text-to-speech and image generation
  • Easy self-hosting via Docker or one-click deploy to Vercel and other platforms
  • Custom assistant 'agents' and a marketplace of prompts and tools
  • Works with your own API keys so you control cost and data
  • Runs LLMs fully offline on your own hardware, so conversations stay private by default
  • Simple point-and-click model downloads from Hugging Face, no command line required
  • Genuinely open source under the permissive Apache-2.0 license
  • Exposes an OpenAI-compatible local API server (localhost:1337) for wiring into other apps
  • Optionally connects to cloud providers and supports MCP for agent-style tool use
Cons
  • Not strict open source: built on Apache-2.0 but with additional conditions that require a commercial license for certain modified-distribution and commercial uses
  • Bring-your-own-key means you still pay each provider and must manage keys yourself
  • The breadth of features and settings can feel heavy for someone who only wants basic chat
  • Full-featured self-hosting (auth, database, file storage) is more involved than the minimal single-container demo
  • Local model quality depends heavily on your RAM and GPU; small models are far weaker than ChatGPT or Claude
  • Decent performance effectively needs 16GB+ RAM and ideally a supported GPU
  • Still maturing, with a fairly high open issue count and occasional rough edges
  • Building from source on Windows is involved and requires a full compiler toolchain
