Every Pro service - auth, mail, uploads, SQL, checkout, OTP login, throttling, reCAPTCHA, Turnstile and client-side validation - for every project you build, including client work.
After you pay, open the receipt Polar emails you, follow the link to your customer portal, and click Connect GitHub account. GitHub will then invite you to the private repo; accept it and composer require flickphp/pro. There's no license key and nothing to activate.
While you're subscribed you get every new version and every new Pro service we add, and each one is yours for good. If you let the subscription lapse you stop getting new ones, but everything you already have keeps working.
30 days, no questions asked, if it's not for you.
