CheckerLoL is a desktop app for checking League of Legends account inventory via the LCU API. Manage a login:password queue, sign in manually in the client, scan, and review results in a single window.
- Account queue — add accounts one by one or bulk-import from text/file (
login:password, optional comment after a space) - Folders — group accounts, create, rename, delete, and move between folders
- Manual login — the app does not log in for you: copy login/password, sign in in the client, then click Scan
- Inventory scan via LCU:
- champions and skins (with images from Community Dragon)
- loot, currency, and shards
- level, server, Blue Essence
- email status (bound / verified)
- last played match (mode, KDA, result, duration)
- Export results to CSV and JSON
- RU / EN interface
- Local storage — passwords and data stay on your PC (
data/accounts.json)
- Launch League of Legends (the client must be running).
- Add accounts to the queue or import a list.
- Select an account → copy the login and password.
- Sign in manually in the client.
- Click Scan — the app reads inventory through LCU.
- Move to the next account with Next.
- Windows
- Python 3.10+
- League of Legends client installed and running
