headless
Install

Free forever.
Two lines and a prompt.

No account, no trial, no meter. Install it, open a folder and ask for something: headless is free to run for as long as you keep using it, from the first prompt to the thousandth.

01 · Downloads

One price, every platform.

Nothing here is metered, gated or tied to an account. Pick the build for the machine in front of you, or take the one command and let it sort itself out.

Checking for the latest build

The rows read the releases page each time you load this one, so they never point at a stale build. Until the first release is public a row says so rather than offering a link that goes nowhere. The command path works today and is the one everything else wraps.

Run
$npm install
$cd your-project
$headless "explain this repo"

02 · Setup

Three beats, then it is running.

There is no configuration file to write and nothing to register. The shortest path is the intended one.

01

Install it.

One command, wherever Node already lives. No account to make, no service to reach, nothing left running when you are done, and nothing to pay for later.

Node ≥ 26.4
02

Open a folder.

Run it inside the project you want it to work on. That folder becomes the whole world the tools can see.

cd your-project
03

Ask for something.

Type the task and watch the loop: read, plan one move, call one tool, print the result, and go again. There is no usage meter above it.

Free forever
