 _Fredy_ is supported by JetBrains under Open Source Support Program

 If you need more than the 1000 API calls allowed per month, I'd suggest opting for a paid account... ScrapingAnt loves OpenSource, therefore they have decided to give all _Fredy_ users a 10% discount by using the code **FREDY10** (Disclaimer: I do not earn any money for recommending their service).

+# Analytics
+Fredy is completely free (and will always remain free). However, it would be a huge help if you’d allow me to collect some analytical data. 
+Before you freak out, let me explain...         
+If you agree, Fredy will send a ping to my Mixpanel project each time it runs.   
+The data includes: names of active adapters/providers, OS, architecture, Node version, and language. The information is entirely anonymous and helps me understand which adapters/providers are most frequently used.</p>
+**Thanks**🤘
