Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Opens the specified URL in the platform's default web browser.
Caveats & Gotchas
- • No allowlist or validation is applied here — any URL is opened as-is. If the URL can come from user input or remote data, prefer LaunchExternalUrl with a domain allowlist to avoid an open-redirect-style vector.
- • Behavior is platform-dependent: on consoles or restricted platforms this may fail silently or be a no-op rather than actually launching a browser.
- • The call is fire-and-forget — there's no return value or callback indicating whether the browser actually opened.
