Overview
Big-AGI Open is the self-hostable web app behind big-agi.com, deployable via Docker or Vercel. It connects 20+ LLM services and 500+ models with your own API keys, and its Beam feature runs one prompt across several models and merges the answers. Personas, request inspection, web search with citations, image generation and multi-vendor speech are included; data stays local-first in the browser.
Who it is for: Power users comparing several models side by side with their own keys

- 20+ LLM services incl. Anthropic, OpenAI, Gemini, Ollama, LM Studio, LocalAI, Bedrock, Groq
- AI Inspector shows the exact requests sent to each provider
- MIT license; no usage charges, bring your own keys
Weaknesses
- Cross-device sync and 1 GB storage only on the hosted Pro tier at $10.99/month

- README omits stack, ports and resource requirements; install guide lives in docs/
- README is mostly badges, taglines and release notes rather than specs
