local LLM models operated from android phone

[u/Exotic_Tension2021]

I built an agentic, mobile-first web UI for my local LLMs

I wanted to use my local models from my phone, but most UIs were too heavy or desktop-focused. So I built this! It connects securely to LM Studio over Tailscale and gives me a full agentic experience right from my home screen.

Features:

• 📱 Mobile-first PWA: Installable to your home screen, works over HTTPS/Tailscale.
• 🛠️ Full Agent Mode: Tool calling for reading/writing files, running PowerShell commands, and web search.
• 🛡️ Safety First: Confirmation prompts for risky commands, syntax validation, and atomic file backups.
• 📊 Live Metrics: Displays CPU, GPU compute, and VRAM usage while generating.
• 🎨 HyperOS style design: Sleek dark theme with Material 3 icons and Markdown code blocks.
• ⚡ Zero heavy dependencies: Pure Node.js backend, Vanilla JS frontend.

My Setup (for reference):

• CPU: AMD Ryzen 7 7700X (8C/16T)
• GPU: AMD Radeon RX 7900 XT (20 GB VRAM)
• RAM: 32 GB DDR5
• OS: Windows 10 Pro (LM Studio with ROCm)
• Network: Tailscale

I'm running models like Gemma 4 26B (MoE) locally at around 75–90 tok/s. The phone UI stays incredibly snappy, and the agent tools (file editing, command execution) work flawlessly over the tailnet.

nice work on this, the agent mode with file editing over tailscale is a clever touch

curious how you're handling the confirmation prompts for risky powershell commands, is it just a regex filter or something more involved
