Formerly Better Chatbot. Navigator is an open-source AI workspace for agents, MCP and workflow automation.
A Next.js AI chat workspace that wraps multiple LLM providers (OpenAI, Anthropic, Google, Ollama, xAI) behind a unified UI with first-class MCP client support, a visual workflow builder, and OpenAI Realtime voice integration. Originally 'better-chatbot' by cgoinglove; this repo is a fork rebranded as 'Keinsaas Navigator' — the original author is still credited but the ownership transfer is opaque. For teams that want a self-hosted ChatGPT-like interface with MCP tool orchestration, it covers a lot of ground.
MCP integration goes deeper than most alternatives — you can invoke MCP servers from voice chat, which almost nobody else has shipped. The visual workflow builder turning node graphs into callable @tools is genuinely useful for building multi-step agent pipelines without code. Tool Choice Mode (auto/manual/none per-message) is a small UX detail that matters a lot when you're debugging agent behavior. Docker Compose setup is actually complete — postgres, migrations, and app in one command, not 'just add your own DB'.
The README lists 'Gemini Nano Banana' as an image generation model name — that's test content that made it into the docs, which is a signal about documentation hygiene. File storage defaults to Vercel Blob with S3 listed as 'coming soon', so self-hosting without Vercel means you're on your own for file uploads. The JS/Python code executor gets one paragraph with no mention of sandboxing — running user-supplied code in a web worker is fine for JS, but Python execution source isn't explained and the security story is absent. RAG is on the roadmap but absent, so it's not useful yet for anything document-heavy.
