A self-hosted AI agent platform built and battle-tested on a Galaxy S21. The full stack — local + cloud inference, Telegram/SMS/web chat, tool integrations (Calendar, Jira, email, deploy), persistent memory, and a web presence with blog and lead outreach — runs on a single phone with zero cloud compute. Most agent frameworks give you building blocks. Palmtop gives you a running product. Clone it, edit config.toml, and you have a production agent with your name, personality, and brand.





Hey PH! I'm Julian — I built Palmtop because I wanted an AI agent I could actually trust with my business operations, running on hardware I control.
The origin story is weird: I had a Galaxy S21 sitting in a drawer and wondered if I could turn it into a full AI agent server. Turns out you can. The S21's Mali GPU runs quantized models via Vulkan, Cloudflare Tunnel gives it a public URL, and Termux turns Android into a real Linux environment.
What started as an experiment became the production stack behind julianbaxter.com — an AI agent that handles lead qualification, scheduling, email outreach, and project management for a freelance software practice. It's been running 24/7.
I'm open-sourcing the whole thing because the "build your own agent" space is dominated by frameworks that give you building blocks but no finished product. Palmtop is the opposite — fork it, fill in your persona config, and you have a working agent with real channels, real tools, and a real web presence.
The persona system means you can make it fully yours. Change the name, personality, services, brand colors — everything is driven by a single config file. No code changes needed.
Would love feedback. What integrations would you want to see next?
