Storage
Upload stays on your bucket. By default Refirebase does not mint a long-lived download URL.

const uploaded = await db.storage.upload(
`playground/${file.name}`,
file,
);
const bytes = await db.storage.getBytes(uploaded.path);Connect a Firebase project
Paste your web config on the credentials page. Nothing is saved on our side — the SDK talks to Firebase from this tab only.
