Used to be soooooooo fun🤩 - but now it doesn't work😡

5 stars before the servers crashed. But before, worked really well, and was very useful. I hope the servers will be back, since alternatives are limited (literally only 1), and are hard to use, unlike BlockLive (which is this).

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.
