Let your AI assistant build a runnable Symfony 8, Laravel 13 or plain PHP 8.5 project and hand you a shareable link. The code runs in the browser with WebAssembly: no install, no account, nothing stored server-side (the code travels inside the link). Tools: get_starter (starting project, editable paths, Composer packages), create_sandbox (builds the link), read_sandbox (reads the code behind a link). Great for demos, answering questions with runnable code, or turning a bug from your project into
