  • (2024-06-16) 伊藤瑠衣: 2023年8月15日 開けなくなりました。機能としては最高の部類なんですが… 追記(2024年6月16日)再インストールしたら大丈夫でした!スクラッチャーにもなれたので、これからも使っていきたいです。
  • (2023-11-26) Aarush Kalele: This is the greatest scratch mod ever and I wish all of these ideas were in real scratch! My favorite features include the pause button, mouse position display, editor find bar, jump to block definition, convert variable to this sprite only, clone counter, running block border, and the debugger panel because these features make it so much easier to find and fix bugs in scratch games! Everyone who uses scratch a lot because not only does it make coding a lot easier, it also improves other aspects of scratch like adding customizable website themes, speeding up project loading times, being able to set a project thumbnail, and a lot more that I would list if it weren't for the fact that there's over 100 addons that you should find out for yourself. Making sprite costumes is also super easy with opacity sliders, skewing, edge snapping, and onion skinning. If it weren't for all that, there's also an option to enable cat blocks, which no scratcher should be without. Finally, the most useful feature is the built-in message notification system that lets you read and reply to comments from other scratchers through the extension pop-up without ever leaving the game you're working on! If you don't already, you should get this extension, because scratch just isn't the same without it,. Thank you griffpatch (and everyone else who made addons and fixed all the bugs)!
  • (2023-11-11) AroAceAutisticChemist: Its good, but i honestly want a merging/cutting/dividing shapes addon. I dont wanna remake the borders of specific shapes just for something i wanna do.
  • (2023-11-04) Caven Bonsell: It stopped working after like a year. No addons show up and dark mode does not work. Scratch Addons is terrible. I contacted Scratch Addons and switched to a different Scratch customizor until this problem is fixed. Edit: Chrome keeps saying it may be corrupted. Is this Chrome or the extension's fault? It does not do it in Edge. Most likely it's Chrome. DAMN YOU CHROME!!! CONSPIRACY!!!!===
  • (2023-11-01) Zohan The Gamer: This is really cool but the problem is every time when i paste stuff to another, it keep on keeping what i pasted last time! I even tried to turn off do not shift pasted items and it still did not work, please add on to fix pasting errors like mine because this is not okay. It is pretty cool though but some errors
  • (2023-10-17) Dr Divya Kumari Tanwar: wow cool
  • (2023-10-14) HoB: Really cool extension...have some bugs but it still make the work alot easier...I would appreciate if they make something like a login feature so that we dont have to import data when we switch browsers or something
  • (2023-10-11) Armando Villalba: es-increible-esta-extencion es-lo mejor-de-scratch
  • (2023-10-09) TaelsDaFoox “Taels”: This might as well be Scratch 4.0 with how many fully customizable features and quality of life improvements this extention adds. From basic fixes that everyone should be using to more specific features for more experienced scratchers, there's absolutely no reason why you shouldn't get this extention!
  • (2023-10-01) benji bon: amazing, was able to switch all my variables to "for this sprite only" and it only took a few seconds, as apposed to the 20 mins it probably would've taken me. pause feature is really great too
  • (2023-09-24) Simocas: Maravilhoso!
  • (2023-09-21) goatboy: i cant see anything no options pls fix i dont see nothin
  • (2023-09-18) Nathan Keyes: Loved it! Has so many options, opacity slider (best of all), and much more! Tbh if I could I'd rate it 100 stars out of 5
  • (2023-09-15) Rocco Anastasio: good
  • (2023-09-11) まっさー、: とても楽に使えています。もうこれなしでは回らないかもです(笑) アップデートもかなり頻繁に入るので、どんどん使いやすくなっています。 とてもいい機能だと思います!!!
  • (2023-09-01) joaoguijz10: salva vidas
  • (2023-08-30) Bilyez ka: This thing, is so AWESOME! Scratch addons saved me so much time. The only thing is that i don't understand how to use folders.. Great extension!
  • (2023-08-29) Enzo Matos: MUITO BOM ESSA EXTENÇÃO
  • (2023-08-22) Dylan McCune: Good soup
  • (2023-08-18) Pengo Storm Alternate: Hey! This sounds EXACTLY like TurboWarp, a Scratch mod that lets you run Scratch projects faster! It comes with onion skinning, custom fps mode, and even interpolation!
  • (2023-08-14) priusup: Scratcherは全員入れたほうがいい、神拡張機能です! ですが翻訳がたまにおかしくなるので、そこは少し残念です。。。
  • (2023-08-11) Рома Касьян: Really epic! I love it!
  • (2023-08-10) Matthew Roughton (ArbestRiAgain): Filter messages addon makes every message disappear, hopefully it gets fixed
  • (2023-08-10) JOAO GABRIEL TRIGO NANBA: eu gostei, a extensão te dá muitos novos itens, mas o problema é que uma hora ele meio que acaba morrendo e tudo que eu customizei acaba voltando ao normal. agora ele não funciona mais =(
  • (2023-07-24) yande estrada: is real good i wish late saw this
  • (2023-07-16) Krishgamer101: This addon for scratch opens many doors, especially when its so easy to get as an extension. All you have to do is click it in your extension toolbar and it works! There are so many options, some which are enabled by default. I recommend this to anyone! [sorry its so big]
  • (2023-07-15) Quang Minh Nguyễn Việt: This extension is good for Scratchers!
  • (2023-07-14) ImmortalWasTaken: I turned on sync and it wont sync to my device what do i do?
  • (2023-07-13) Desmond Peveril: i am just confused. i downloaded it i think but idk how to use it. i believe it is really great but idk how
  • (2023-07-03) 0je14l3q8: This is the best addon to use on scratch. Many settings so you can customize scratch to your liking! This is really a recommended addon and you should download it!
  • (2023-07-03) Jordan Ramkirpaul: Its good but the "Customizeable Navigation Bar" Setting Breaks Scratch For example "When you enable it and turn projects/editor To projects/create It shows an ERROR Sign
  • (2023-07-02) ItsMeMakesVideos Yt: Honestly its a W, nothing bad about, just don't put on every single add-on like I did...
  • (2023-07-02) Tima. Ru: лучшее дополнение
  • (2023-06-30) Loganboi2 (LoganPlays): I don't know what to even say. This is completely broken every time I've tried to use it in the past few days. It opens, but then the addons don't even exist. There's nothing that it shows me, and no videos tell me how to fix this. I'm probably not re-reviewing until it actually explains how to fix it. It worked before hand and was good, but then all my addons got deleted and I couldn't use it anymore.
  • (2023-06-27) The E God: If you use scratch a lot. Either to make games, play them, and/or just talking through messages, scratch addons covers all of that. Scratch addons can help you by showing possible glitches like more clones then there should be. There's the 60 FPS button, which can be set to 240 FPS, so if you have a boring un-skippable cutscene, you can go through it 8 times as fast, Scratch addon will notify you whenever you receive a message, so if you are talking with someone, you can do other stuffs while scratch addon detects when the message is sent. You can even reply just by pressing the scratch addon extension button, meaning you can watch YouTube while replying to someone who sent you somethin on scratch. There is also visual stuff, like dark mode. Overall, scratch addon has been really helpful in the time I have been using scratch. It's like a whole entire different experience.
  • (2023-06-24) Rex Chang: AWESOME :DDDDD Wait... CAT! CAT! CAT!
  • (2023-06-23) Peverley Hormann: It's a good app, but for some reason, it is disabled in my browser and my device is compatible!
  • (2023-06-22) Matypo22 (Matypo): C'est super cool d'avoir se genre d'extension !!!
  • (2023-06-22) Chloe White: i love this but theres a bug where when you install it the thumnail to studios and projects a blanc
  • (2023-06-20) Clovir Studios: If you use Scratch, you use Scratch Addons, it's that simple. The developer community is very active, so don't pay attention to all the reviews about bugs, chances are it's been fixed by now.
  • (2023-06-16) murilo schuch: Muito bom,resolveu vários problemas do Scratch e trouxe o modo escuro. Pelo menos agora meus olhos não quando tô programando de madrugada.
  • (2023-06-11) randall austin: even though the ps3 control axis 2&3 is encoded wrong on the game pad extension, I like it.
  • (2023-06-06) Isabelle Call: I love everything about this extension definitely get it there's sooo many things that it adds to scratch. The onion skinning for animation and the clone counter is great. THE MOUSE POSITION THING IS THE BEST OMG.

  • (2023-05-14) Xander Young: THIS IS AMAZING!!!!11!11!!!!11!!1 You can add SO MANY FREAKING THINGS TO SCRATCH. The most helpful ones to me were the volume slider and the pause button. I LOVE IT!1

  • (2022-08-04, v:1.27.3) Brett Flannery: Program Gamepad Buttons
    I have a need to have two joysticks with different button mapping for each in a program. It works with the gamepad support if I change them in the program but there is no way to save the different configurations. Every time I open the program they default to both being the same. If you can add a feature to be able to save multiple configurations so joystick 1 map, joystick 2 map, ect that would make my project work. Thanks

    I want to use it in an InPrivate window, because I don't really have a device so I use my brother's computer, and I don't want to add stuff to their history. But I wanna use this extension. Please add support for InPrivate/Incognito windows. (If you are wondering what I mean, on Microsoft Edge, if you have an extension you can go to edge://extensions/ and then press "Details" on an extension and then most of the time there will be an option saying "Allow in InPrivate".)
