Piumy — a self-hosted WhatsApp assistant on a Raspberry Pi (or your PC) that your own AI runs over MCP. Open-source, with an e-paper pwnagotchi face 🦉
I built Piumy: a tiny WhatsApp switchboard you fully own. The idea is simple — the board never thinks, it routes and stores. It receives your WhatsApp, keeps every message (text, photos, videos, voice notes, stickers) in its own database, and exposes everything over MCP so your AI agent (Claude, OpenCode, whatever) connects and does the replying — from a machine with real RAM, on your terms.
A few things I care about:
- You're always in control. New chats arrive ignored — nothing gets answered until you write the rule for that chat (from the dashboard, or just by texting your Piumy number). Whitelist by default.
- Your history is yours. If a contact deletes the chat or you lose your phone, it's still here — self-hosted, not locked in a cloud.
- Runs on a $15 Raspberry Pi Zero 2 W with an always-on e-paper face (a homage to pwnagotchi) — or as a plain binary on your PC (Windows/Mac/Linux).
- Anti-ban by design: human pacing, rate limits, kill switch, whitelist. Only ever replies to inbound.
It's free and open-source (AGPL-3.0). I'm a solo dev — donations are literally what decides whether this grows past the MVP, so if it speaks to you, you can pay what you want (even $0).
