Stremio doesn't let you change the email on an account. So if you ever need to move to a new one — new email, got locked out, whatever the reason — you're stuck manually re-adding every show and movie by hand. This is a small tool that copies your library and installed addons straight from one account into another.
It's one file, index.html. No install, no build step, no server — open it in a browser and it talks directly to Stremio's own API. Nothing passes through a third party; your credentials and library data go from your browser to Stremio's servers and nowhere else, same as the official app.
- Open
index.htmlin a browser. - Under Source account, log in with the account you're moving from and hit Login + Fetch. It pulls your library and addons, runs a quick sanity check on the data (more on that below), and gives you a "Download backup JSON" link — worth grabbing as a safety net. If you've already got a backup from a previous run, use Import backup JSON instead of logging in again.
- Under Destination account, log in with the account you're moving to.
- Click Migrate library & addons.
Running it more than once is safe — library items keep their original IDs, so migrating again overwrites rather than duplicating.
Every fetch gets checked for duplicate IDs, missing fields, and bad or empty timestamps, with a short report shown right in the UI. Anything broken is patched automatically before it's sent anywhere — no corrupted entries making it into your new account.
- Nothing is written to disk unless you click the backup download link yourself.
- This relies on Stremio's web API, which is stable in practice but not an officially documented public API — the same one the official apps use. If Stremio changes it, this may need an update.
