Frequently Asked Questions

Android 7+ with at least 2GB RAM. Install Termux from F-Droid (not Play Store). Tested on Samsung A8 Star (Android 10, 3.6GB RAM).
No root required. Everything runs inside Termux (a regular Android app) with wake-lock and standard APIs.
$0/month. Zero. You only pay for electricity (phone charger) and WiFi. All software is free: Node.js, SQLite, OpenClaw, OpenRouter (free tier available).
VPS is more stable and suitable for 24/7 production. An old phone is great for personal projects, learning, or light services. Phone bonus: zero server cost, portable, has a built-in UPS (battery).
Charging 24/7 accelerates battery degradation and risk of swelling. Use a 5W charger (not fast-charge) and ensure ventilation. This kit is an experiment, not an enterprise server.
Yes. You only need to: (1) install Termux, (2) fill in 3 tokens (guide included), (3) run the script. Step-by-step tutorial included. ~15 minutes.
Free, open source (MIT). No catch. Clone the repo directly from GitHub. If it helps you and you want to show appreciation, tip what you want via PayPal or BTC — completely voluntary.
