I wanted something like Claude Code — but completely offline, on any laptop,
with nothing installed on the host machine.

So I built code-stick.

What it is

A CLI that turns any USB drive into a portable, self-contained AI coding agent.
You get file editing, multi-step tasks, and tool use — running entirely on the
stick against a local model. No internet. No installs. Nothing left on the host
when you unplug.

How it works

Run this once on your own machine:

npx code-stick install

Pick a model — Qwen2.5-Coder, DeepSeek-Coder, CodeGemma, or Phi-3.

It downloads everything onto the USB:

• opencode + Ollama pre-built binaries for all five targets
• Model weights in a USB-local Ollama store
• Three launchers at the root: start-windows.bat, start-mac.command, start-linux.sh

From that point on, plug into any Windows, macOS, or Linux laptop, double-click
the matching launcher, and you get a full coding agent running at 127.0.0.1.

Quit → Ollama process killed by PID → host stays completely clean.

Why I built it

Three situations cloud agents can't serve:

Airgapped environments — banks, hospitals, defense, lab VMs where you can't
install software or call external APIs.

Shared or borrowed machines — school computers, client laptops, internships
where the host must stay untouched.

Privacy-sensitive code — NDA'd or client code that legally can't go to a
hosted model.

Current state

v0.1.0 — early but working:

• Tested end-to-end on all five targets
• Docker-based smoke test in CI + Vitest unit suite
• Crash reports are local-only, no auto-upload, no telemetry
• MIT licensed, Node 20+

Would love feedback — especially on model selection, USB performance, and any
edge cases on your OS.
