Show HN: Nemilia – multi-agent AI workspace in a single HTML file, no back end

3 months ago

A full multi-agent AI workspace in a single HTML file. No backend. No install. No build step. No account. You own the entire runtime — open it in a browser and it works.

That's not a constraint. That's the point.

Nemilia is built around the idea of AI sovereignty — your agents, your workflows, your data, your keys, all running on your machine. Nothing phoned home, nothing locked to a platform, nothing that breaks when a SaaS company changes its pricing.

What you get: - Build custom agents with their own roles, personalities, system prompts, and model overrides - Design custom workflows with drag-and-drop pipeline builder — chain agents in any order, set HITL review checkpoints, run parallel DAG execution - MCP tool execution — build agents that call external tools in real time (filesystem, databases, APIs, code execution) over streamableHttp or SSE - Document RAG with hybrid Transformers.js vector embeddings + BM25 keyword search, fully client-side - WebGPU offline mode — run Llama, Qwen, Phi, Gemma entirely in the browser, no API key, no internet - Connect any provider: OpenAI, Anthropic, Groq, Gemini, Mistral, DeepSeek, Ollama, LM Studio — swap anytime, your workflows follow - API keys encrypted AES-256-GCM, never leave your browser - Workspace syncs to a real folder on disk as plain JSON and Markdown — version control it, edit it in VS Code, take it anywhere

One file. Any browser. Your AI team.

Getting started takes about 60 seconds: download the file, open it, paste any API key, point it at LM Studio/JAN, or load up a model directly into your browser via WebGPU.

Released it publicly last week. Would genuinely love feedback.

P.S. Nemilia means "to think, to remember, to imagine" in Nahuatl, the language of the Aztecs. Felt like the right name for something that does all three.
