ScriptPanda vs Tampermonkey

18 October 2026 · 4 min read

Quick answer

Tampermonkey is a userscript manager: it runs scripts you find or write yourself, and supports the GM_ functions many published scripts rely on. ScriptPanda writes a script for you from a plain-English description on the page you're on. It doesn't run existing Tampermonkey scripts. Many people use both.

Two tools for the same idea

Both tools run userscripts: small JavaScript programs that change a website after it loads. They differ in where the script comes from. With Tampermonkey you bring the script. With ScriptPanda you describe what you want and it writes the script. That one difference decides which you need.

What Tampermonkey does

Tampermonkey is one of the most widely used Chrome extensions, with about 12 million users and a rating of about 4.7 on the Chrome Web Store as of October 2026. Its listing describes it as a way to "change the web at will with userscripts", and lists features including:

  • managing and editing your scripts in one place;
  • turning scripts on and off quickly;
  • syncing scripts through Chrome Sync or cloud storage such as Google Drive and Dropbox;
  • backing scripts up and restoring them;
  • updating scripts automatically.

It supports the GM_ functions, the special abilities userscripts can ask for in their header, such as storing values or making requests to other sites. That matters because thousands of scripts published on sites like Greasy Fork use them. If you want to install an existing script someone else wrote, Tampermonkey is built for exactly that.

What it doesn't do is write scripts for you. You find one that does what you want, or you write it, or you ask a chat assistant for one and paste it in.

What ScriptPanda does

ScriptPanda is a Chrome extension that builds the script from a description. You open its side panel on the site you want to change, say what you want in plain English, and it writes a userscript for that page, installs it and runs it. Because it reads a trimmed outline of the page's structure when you send the request, it can find the real heading, list or button, instead of guessing as a chatbot does when it has never seen the page.

The tools it builds are stored in your browser, in the extension's local storage, not on ScriptPanda's servers. If a site changes and a tool breaks, you ask ScriptPanda to fix it for the page as it is now. If you know JavaScript, you can open any tool's code and edit it.

ScriptPanda doesn't run existing Tampermonkey scripts, and it isn't a manager for scripts you've collected. It's for the scripts that don't exist yet.

Which to use

  • You want a script that already exists: Tampermonkey.
  • You write JavaScript and want full control: Tampermonkey, or ScriptPanda's editor if you'd like a first draft written for you.
  • You know what you want and can't find a script for it: ScriptPanda.

Both need Chrome's Allow user scripts setting turned on for them in chrome://extensions. Many people install both: Tampermonkey for the scripts they've collected, ScriptPanda for the ones nobody has written yet.

Try it on this page

The request at the end of this guide adds a button that copies a page's title and URL as a Markdown link. It's a typical small userscript. Paste it into ScriptPanda on any article and compare it with writing the same script yourself.

Limits

Both tools work inside the page, in your browser, while it's open. Neither runs scripts in the background or while Chrome is closed. ScriptPanda builds one tool per page and can't schedule jobs or work across several sites at once. Third-party details here are from Tampermonkey's Chrome Web Store listing as of October 2026 and may change.
