Put a pack back on Scratch.

Open a .scratchpack and scratchup re-creates every game inside it as a project on your Scratch account — assets first, then the project itself. Uploads land unshared in My Stuff.

Go slow. Scratch has no public upload API, so this drives the same endpoints the editor uses. Creating projects in bursts looks like spam and gets accounts banned. The pause below is capped at a minimum of 12 seconds between projects for that reason — don't route around it.

.scratchpack  ·  .scratchplay  ·  .zip  ·  .sb3

2 · Account

In a tab logged in to scratch.mit.edu, open dev tools → Application → Cookies → scratchsessionsid, and copy the value (drop the surrounding quotes). This never sends your password anywhere.

3 · Upload

Nothing queued.

Only upload projects you made or have permission to re-post, and credit the original author in the notes if a game isn't yours.
