About InScript

InScript turns the browser side panel into a JavaScript shell for the current page. Type JavaScript, press Ctrl/Cmd+Enter, and it runs in the active tab's page context (MAIN world) — so it can read the live DOM, the site's own global variables, cookies, and localStorage, and fetch with the page's origin. The result of your last expression is shown REPL-style, along with anything your code logs to the console and any errors with stack traces. Features • Runs in the real page context (MAIN world) — sees the page's actual globals and DOM • REPL-style return value with type, plus full console.* capture • Top-level await and auto-resolved promises • Save and reload snippets; browse run history • Keyboard-first: Ctrl/Cmd+Enter run · Ctrl/Cmd+L clear · Ctrl/Cmd+S save · Alt+Up/Down history • Optional CSP-bypass mode (userScripts API) for sites with a strict Content-Security-Policy
