Specifiers: staticUFUNCTIONBlueprintCallable
Description
Returns whether the current platform is able to launch the given URL in a browser.
Caveats & Gotchas
- • Checks platform capability only — it does not validate the URL's syntax or reachability, and doesn't apply any domain allowlist like LaunchExternalUrl.
- • A true result doesn't guarantee LaunchURL will succeed at the point you actually call it (e.g. no network, browser closed by user), since this is a capability check, not a live connectivity test.
- • Useful for hiding or disabling "open in browser" UI on platforms (consoles, some mobile configurations) where URL launching isn't supported at all.
