Licensing

Getting a License Key

You can get a license key from the web portal or via the CLI.

Run the CLI to register a free 28-day trial:

npx writetrack init

The CLI will prompt for your email and production domain, then save the license key to .env:

WriteTrack — Set up a free 28-day trial

Email address: you@example.com
Production domain (e.g. example.com): example.com

Registering you@example.com for example.com...

Done — license key saved to .env
   Trial expires: 3/10/2026

Then pass the key when initializing:

const tracker = new WriteTrack({
  target: textarea,
  license: process.env.WRITETRACK_LICENSE_KEY,
});

Tip

The CLI writes WRITETRACK_LICENSE_KEY to your .env file and checks that .env is in .gitignore. If you already have a key configured, it will show the existing key instead of registering again.

Evaluation Mode

On localhost, WriteTrack runs with full analysis enabled — no license key required. Use this to evaluate the SDK during development and testing. A license key is required for production deployments.

// Evaluation mode — localhost only, no license required
const tracker = new WriteTrack({ target: textarea });
