The Local-First Agent Starter Kit

Own your AI agents

Generate your first real agent and get it running on your own machine in about 10 minutes. No servers. No API keys. No cloud account — just your own device.

The signal: build and run autonomous AI agents on your own device and your own GitHub account — single-file, no servers, no lock-in — that you can fork, share, and keep. Powered by RAPP.

1Install the brainstem

The brainstem is the runtime — it runs single-file agents on your device. One line, no sign-up:

curl -fsSL https://raw.githubusercontent.com/kody-w/rapp-installer/main/install.sh | bash

Prefer to look before you run? Read the script first at the same URL, or follow the RAPP Bible quickstart.

2Generate your first agent

A RAPP agent is one Python file that "just runs." Describe yours — the kit writes a real, runnable skeleton you own.

What should your agent do? A short name for the capability. e.g. "summarize my standup notes"

Agent name letters/numbers, becomes the class name

Parameters comma-separated inputs it takes

Save it as your_agent.py, drop it into ~/.brainstem/agents/ — and it just runs. No registration, no restart dance.

3Run it — and kite it

Drop the file into your agents folder and the brainstem hatches it as a twin. Then optionally kite it — make it reachable across your devices, sealed end-to-end.

cp your_agent.py ~/.brainstem/agents/
# it's live — talk to it through RACon or the brainstem /chat on localhost:7071

Try the kited demo →
Scan a QR, join a sealed multiplayer neighborhood in real time — the "hello world" of the kite.
Browse the agent registry (RAR) →
Install agents others have shared as .egg cartridges — or publish your own.
Read the RAPP Bible →
The full map: brainstem, RACon, eggs, the kited layer, the neighborhood protocol, MCP.

Get the full kit + the weekly build

Drop your email and I'll send the extended starter kit (3 ready-to-run agents, the kite walkthrough, the MCP on-ramp) plus one local-first agent build per week. Your email stays in your browser — this just opens a message you choose to send. No server, no list broker.

Ready to build the whole stack with me?

The Local-First Agent Lab — a 6-week live build-along. Each week you ship one real, owned thing: brainstem running, your first agent, two devices kited, an egg published, an MCP host calling your agent. You leave with a working stack you own, not a folder of notes.

Local-first & offline: anything you enter stays only in this browser (localStorage), exportable as JSON. Nothing is uploaded.
