How Stateless Smart Links Work

  • 100% Stateless: No database or server is contacted. All data is contained directly inside the URL.
  • Domain Code: Known domains use short 2-letter codes (e.g. gt for github.com, ig for instagram.com).
  • Base64URL Payload: The full remaining path, query string, and hash are UTF-8 encoded into a safe Base64URL string.
  • Native App Launch: Mobile devices attempt to open the corresponding native app with automatic fallback to the web page.
