Pricing FAQs
Everything you need to know about ParrotJS pricing and licenses.
What's included in the Free tier?
The Free tier is free forever and includes inline runtime values, // ? live comments, inline console.log output, inline expect() assertions, sticky values, all three run modes, TypeScript/JSX/TSX/ESM support, configuration profiles, and the process-isolated sandbox. No credit card, no account, no license key required.
What does PRO unlock?
PRO adds Time Travel debugging with the visual timeline, code coverage indicators, auto-log and line values, hover tooltips with deep inspection, the Value Explorer, watch expressions, and the test results panel. It's a one-time payment and yours forever — including a full year of updates.
Is there a free trial?
Yes. You can request a 30-day free trial from inside the extension (ParrotJS: Request Free Trial) — it emails a trial license key that unlocks all PRO features for 30 days. One trial per machine.
How do I buy PRO?
Click "Get PRO" on this page or run ParrotJS: Purchase PRO inside VS Code. You'll complete checkout through Lemon Squeezy (cards and PayPal accepted). Your license key is emailed to you — paste it into ParrotJS: Enter License Key to activate.
Is PRO a subscription?
No. PRO is a perpetual license with a single one-time payment — it never expires and there are no recurring charges, ever.
Does the license cover updates?
Yes — every PRO purchase includes one full year of updates from the date you buy your license: new features, improvements, and fixes at no extra cost. After that year, your license keeps working forever and you keep any version you've installed; grabbing newer releases is simply a new purchase if you want them.
Is my code sent anywhere?
No. ParrotJS runs entirely locally. Each file executes in a forked Node.js child process with process isolation — user code can't crash the IDE. No telemetry, no cloud processing. The only network call is license validation for PRO, which happens everyday.
