  - Deployable on many platforms - thanks to nitro
  - header rewrites - read and write protected headers
  - bypass CORS - always allows browser to send requests through it
+ - secure it with turnstile - prevent bots from using your proxy
+
+> [!WARNING]
+> Turnstile integration only works properly with cloudflare workers as platform
 
 ### supported platforms:
