Allgemeine Fragen

Was ist Scratch Addons?

Scratch Addons ist eine “All-in-One”-Browsererweiterung für die Scratch-Website und den Projekteditor. Es bietet Funktionen und Designs (intern Addons genannt) sowohl für die Scratch-Website als auch für den Projektideditor. Die Mission von Scratch Addons besteht darin, alle vorhandenen Scratch-Erweiterungen, Userscripts und Userstyles, die von mehreren Mitgliedern der Scratch-Community entwickelt wurden, in einem einzigen, leicht zugänglichen Ort zu kombinieren und den Benutzern weiterhin die Auswahl der zu aktivierenden Erweiterungen zu ermöglichen.

Wer hat Scratch Addons gemacht?

Scratch Addons is a team project led by World_Languages. You can find the list of people who have contributed to us on the Credits page. While the “Scratch Messaging” and “Developer tools” addons were initially created by griffpatch, he does not maintain the extension.

What does Scratch Addons include?

Scratch Addons includes over 100 addons, which can be enabled or disabled individually. Some addons can also be further configured, and some have presets, such as dark mode for the website theme. Scratch Addons also includes a popup, which can be used to quickly access messages, cloud games, and the settings page. Scratch Addons is translated into multiple languages, including German, French, Spanish, and Japanese.

Is this the same as TurboWarp Addons?

TurboWarp has some addons from Scratch Addons which can be used on their editor without installing Scratch Addons. However, Scratch Addons also includes addons for the Scratch website and the popup display. Therefore, it is still useful to have Scratch Addons even if you only code using TurboWarp.


What are the system requirements for Scratch Addons?

Scratch Addons is officially supported on the desktop versions of Google Chrome (version 80 and up), Microsoft Edge (version 80 and up), and Mozilla Firefox (version 86 and up), and should also work on other desktop browsers that are based on those browsers. Please check out this page for complete information.

Can I use Scratch Addons on a mobile device?

For Android users: Yes, but it is not recommended. Major browsers do not allow Scratch Addons (or any other extensions) to be installed, so you need to use browsers such as Kiwi to do so. Scratch Addons’ UI is not well-tested on touchscreens or environments with small screen size, so some of the features might not work as expected.

For iOS and iPadOS users: Sadly, it is not. App Store policy does not allow browser implementations to be uploaded, which means all browsers available on that platform are just re-skinned Safari. This causes some problems (see below).

Can I use Scratch Addons on Safari?

Currently, you cannot.

First, Safari extension store requires all developers to pay an annual fee to list extensions on the store. As Scratch Addons team does not have a source of income, this makes it very hard to maintain the extension. There is also a technical problem with the implementation of browser extensions in Safari which makes some of the core features to be unusable.

Can I use Scratch Addons on the offline editor?

Scratch Addons cannot be used on the official Scratch application, including the offline editor.

As an alternative, most of the project editor addons are available on TurboWarp which has a downloadable app for Windows, macOS, and Linux. Additionally, on browsers that support Progressive Web Applications (PWA) such as Google Chrome, you can also install the TurboWarp editor as a PWA and use it without an internet connection.

Are there any incompatible programs?

Some browser extensions and userscripts may interfere with Scratch Addons. If you experience issues, you should try disabling these:

  • Scratch 3 Developer Tools: This browser extension is a copy of the Developer tools addon. You should uninstall the Developer Tools browser extension and turn on the addon instead.
  • Better3.0: This browser extension can interfere with some addons. Luckily, most of its features are also available as addons.

Security and privacy

Ist Scratch Addons sicher?

Yes. Scratch Addons should not have any security issues in its most recent version. Scratch Addons is an open source project, so the code has been reviewed by Scratch Addons contributors. Additionally, Chrome Web Store, Add-ons for Firefox, and Microsoft Edge Add-ons review each new version of Scratch Addons before publishing it on their stores.

Wie kann ich eine Sicherheitsschwäche melden?

If you happen to find a security vulnerability, please contact World_Languages privately by emailing worldxlanguages (at) gmail.com. If you don’t get a response within 48 hours, please create an issue mentioning that you had sent an email.

You can either read our security policy or check our advisories that we have published.

Ist mein Konto sicher, wenn ich Scratch Addons verwende?

Yes. Features related to your Scratch account are thoroughly reviewed by Scratch Addons contributors to ensure that they will not harm your Scratch account. Scratch Addons keeps your account credentials secure, and it will not modify or delete your projects or assets without your permission. However, you may use the extension without any account-related features if you so choose.

Addons auf Scratch Addons wurden auch von mehreren Mitwirkenden im Repository geprüft, sodass niemand nur böswilligen Code unter unsere Augen schieben kann.

We never send any confidential or personally identifying information outside of your browser. See the extension privacy policy for more information.

Using Scratch Addons

How do I enable addons?

To enable addons, first go to the settings by:

Then, find addons you’d like to enable using the sidebar or the search box. To enable an addon, click the switch on the right side of the addon tile.

Kann ich anderen Leuten auf Scratch über Scratch Addons erzählen?

You can’t, and please don’t. There is a policy that forbids mentioning browser extensions/userscripts here, and violations have resulted in Scratch Team removing posts or muting accounts. You may, however, use different methods to tell your friends about Scratch Addons.

Ich denke, dass Scratch Addons Scratch verlangsamt. Was kann ich tun?

You can try disabling addons that you don’t need, especially complex features such as the variables tab, debugger, and cat blocks that watch the mouse pointer. Most addons with a performance impact will provide a warning in the extended addon information.

Some specific advices:

  • Turn off 60FPS addon. While the addon can increase the maximum speed a project can run, it does not reduce lags. To run such projects faster, use TurboWarp.
  • “Variable manager” addon should not be used while the project is running.

I cannot receive notifications. Why?

First, disable and re-enable the “Scratch Notifier” addon. This can fix some issues.

If the problem continues, then check the operating system’s notification settings. You have to allow the browser - such as Google Chrome - to send notifications.

  • Windows: Open Settings, open the “Notifications & actions” category, then find “Change notification settings for individual senders”. Read Microsoft’s help article for more detailed information.
  • macOS: Open System Preferences, then open the Notifications section. Select the browser (e.g. Google Chrome) on the left and enable notifications. Read Apple’s help article for more detailed information.

You should also make sure that “focus assist” (on Windows) or “Do Not Disturb” (on macOS) is disabled.

How do I watch recordings made with the project video recorder addon?

Due to technical limitations, videos recorded with this addon are in the WebM format. You can view .webm files using your browser (by dragging and dropping the file) or by using a media player that supports it, such as VLC Media Player.

To convert WebM files into MP4 or other formats, you can use a video conversion software that supports WebM, such as HandBrake or CloudConvert, although we recommend simply viewing these files with a browser or media player. Note that this can take a long time depending on the size of the video.

Wie kann ich die Easter-Egg-Addons aktivieren?

Um die Easter-Egg-Addons zu enthüllen, mache den Konami-Code (↑↑↓↓←→←→BA) mit deiner Tastatur auf der Einstellungenseite. Danach werden die Easter-Egg-Addons sichtbar sein, um dir den Zugriff darauf zu erlauben.

Manche unserer Easter-Egg-Addons sind “Katzenblöcke” und “Semikolonfehler”. Im Addons-Tab findest du die vollständige Liste.

Was ist ein “Addon” genau?

Ein Addon ähnelt einer Erweiterung oder einem Userscript, verwendet jedoch spezielle APIs, die von der Erweiterung Scratch Addons bereitgestellt werden. Mit diesen APIs können Addons Skripte auf einer Scratch-Seite ausführen (Userscripts), Skripte im Hintergrund ausführen (persistente Skripte) oder Stile auf die Scratch-Website (Userstyles) anwenden.

Userscripts can use the addon.* JavaScript APIs, which allow them to obtain Scratch-related information (for example, the currently logged in user) and use extension APIs (like sending notifications).

Wenn alles ein Addon ist, was macht Scratch Addons dann?

By itself, Scratch Addons is just an addon loader. Its main tasks are to:

  • Erlaubt es Nutzern, Addons zu deaktivieren und zu konfigurieren.
  • Addons ausführen und APIs dafür bereitzustellen.
  • Provide useful data to addons (for example, the addon.auth API).
  • Erstellen von Prototypen zur Verwendung durch Addon-Userscripts.
  • Methoden zum Zugreifen und Bearbeiten des Redux-Status bereitstellen.
  • Vermeiden, dass sich Addons untereinander behindern.
  • Doppelte Arbeit von verschiedenen Addons vermeiden.
