Free to start. Pro when you run many.

Two things: running more than one browser at a time (up to 250 at once, on any number of machines), and email support from me, the owner. The build is identical. If you only ever run one browser at a time, Free with GitHub gives you everything the build does.

No. The open build has full engine-level fingerprint control and is reproducible from source — every identity surface is in it: Seeded identities — same seed, same browser; different seed, unlinkable, Full engine-level fingerprint control, Individual metadata overrides — screen, memory, pixel ratio, GPU and more, Light-stealth preset for targets that need a lighter touch, TLS fingerprint matched to the browser version you present, Proxy support with automatic timezone and language matching. The licensed build adds things that do not spoof anything new: humanized input driven by real recorded human motion, higher-fidelity pointer reporting, webrtc reports your proxy's address, not your machine's, local network addresses stay private over webrtc, request-header handling tuned for repeat visits, plus new Chromium majors first. All of that is free with a GitHub account for one browser.

Yes. A 30-day pass is $49, paid once — same build, same private patches, same concurrency, same direct support. The only difference is that it ends on its own instead of renewing, so there is no subscription and nothing to cancel. Buy another one whenever you want more time and it adds to the license you already have: your existing key keeps working, nothing to redeploy. There's a second reason it exists — Stripe can only charge a subset of payment methods on a recurring basis, so subscribing shows most people a card field and not much else. Paying once lets you use PayPal, Apple Pay or Amazon Pay instead.

Anytime, from the billing portal in your dashboard. You keep access until the end of the period. A one-off pass has nothing to cancel — it simply stops at its end date.
