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.

Scratchers can opt out of having their games re-uploaded by others by putting
backup:off in their About Me. scratchup looks up who made each game in the pack
and locks the ones whose author opted out.

scratchsessionsid, and copy the value (drop the surrounding quotes).
This never sends your password anywhere.
Your password goes to your own worker, which forwards it to Scratch's login endpoint and keeps nothing. Scratch sometimes blocks logins coming from datacenter IPs — if that happens, use a session ID.
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.
