Mia V2024年6月5日

It was great until the creator decided to put MALWARE FOR FOLLOWERS. That is just stupid and wrong, trying to get fame. Not like I have seen that before.

Crazygamer7592024年6月4日

please come back, i need this extensions to Collab with my best friend and if it's gone we're gonna leak everything every time we Collab! Also my friend isn't allowed to get discord so this is one of the only ways we can talk in private!

Wheat Bread2024年6月4日

undo button sudden never works. gets rid of what i create randomly doesn't update the project live so you constantly have to reload the page and end then its not going to 100% work worst thing i have ever used

Great, I guess, only issue is that I heard that there was a Malicous code saying that anyone who uses blocklive follows a dev of blocklive? After I'm done writing this review, I can't trust it, not right now, However I'll give my opinion on blocklive, it's a really good extension, I used it to make a multiplayer scratch project, however, now that I know that blocklive had this malicous code (I know they removed it but I don't wanna risk it), I'm gonna stop using this extension, I'll use it again if It's trustable again, Thanks for reading my reviews, This was just my first review, but anyways, bye and stay safe everyone.

Real-time collaborative editing of Scratch projects

Scratch's native editor is single-user only; Blocklive enables multiple Scratchers to work on the same project simultaneously in real time

1. User installs extension and is prompted to log into Scratch (scratch.mit.edu). 2. The extension verifies the user's Scratch identity via a cloud-variable challenge (sets a code as a cloud variable on a verification project, then retrieves a Blocklive API token). 3. User adds friends' Scratch usernames to an allow list in the popup. 4. When a user opens a Scratch project editor, the extension injects collaboration UI and connects to the Blocklive websocket server. 5. Changes to the project (blocks, sprites, scripts) are synced in real time to all connected collaborators via socket.io and the livescratchapi.waakul.com server. 6. Users can chat within projects and receive notifications of activity.

Target users: Scratch developers and students who want to collaborate on projects in real time / Scratch educators and teams working on shared coding projects

The extension has multiple popup variants (popups/, popups-blorig/, popups-lsorig/) suggesting historical evolution; the analysis focused on the primary popups/ directory.
The scripts/editor.js file is very large (3967 lines / 154KB) and only partially reviewed, but the key workflow elements were identified from the background and auth scripts.
Cannot confirm whether the Blocklive API server itself has any paid tiers or rate limits from the extension code alone.

Monetization

No paid features detected

The deterministic heuristic flagged 'subscribe' and 'upgrade' keywords, but all hits are false positives from the socket.io library (event subscription and transport upgrade terminology, not billing). The 'pro' hits are from 'project' and 'Promise'. No payment UI, billing API calls, plan checks, Stripe/payment platform integrations, or feature-gating code were found. The extension has a Ko-fi donation link (ko-fi.com/waakul) but this is voluntary donations, not paid features. All core collaboration features appear freely available.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension requires the user to be logged into Scratch (scratch.mit.edu). It fetches the Scratch session endpoint to detect login status (background.js line 231: `res = await fetch('https://scratch.mit.edu/session/?blreferer', {`), and if the user is not logged in, the popup displays a message blocking the UI: 'Uh oh! Youre not logged in! Log in to scratch to use blocklive!' (popup.html line 149). Additionally, the extension performs a cloud-variable-based verification flow (auth.js / verify.js) to obtain a Blocklive API token, which is sent as an authorization header on all API calls to livescratchapi.waakul.com.
