LobeChat

LobeChat (by LobeHub) is an open-source-style chat application that puts GPT, Claude, Gemini, DeepSeek, local models and 40+ other providers behind a single refined interface. It runs as a hosted app (app.lobehub.com) or self-hosted via one-click Vercel/Zeabur/Sealos/Alibaba deploys or Docker, with your own API keys. Beyond chat, it ships a knowledge base for RAG over your documents, a plugin and MCP-compatible tool ecosystem, an agent builder with custom system prompts and tools, multi-session/topic organization, TTS/STT voice, and art/image generation. Note the licensing nuance: since v1.0 it is distributed under the custom LobeHub Community License (Apache-2.0-based with a commercial-derivative restriction), which is source-available rather than OSI open source. The project is currently evolving from a chat client into the broader LobeHub 'agent operator' platform.

Option A — Vercel one-click (no server)

1. Fork/star the repo, click the Vercel deploy button in the README
2. Set the OPENAI_API_KEY environment variable (or other provider keys) during deploy
3. Open your deployment URL and start chatting

Option B — Docker (recommended for full self-host)

1. mkdir lobehub-db && cd lobehub-db
2. bash <(curl -fsSL https://lobe.li/setup.sh) — initializes the database/infrastructure
3. docker compose up -d — starts the LobeHub service (chat + server DB)
4. Open http://localhost:3210 and add your provider API keys in Settings

Option C — npm / source

1. npm install -g @lobehub/chat or clone the repo and run bun install && bun run dev
2. Configure provider keys via environment variables or the in-app settings panel
