Use Glitch Live Preview to instantly see client‑side changes in the browser, know when to restart the server for backend changes, and troubleshoot common hiccups.
Stackblitz Live Preview turns your editor into a live sandbox, eliminating build wait times. In this guide we walk through a React example, compare it to a local dev server, discuss trade‑offs, and give practical next steps for a hybrid workflow.
