A fast, local-first account manager and auto-login for League of Legends and VALORANT.
Nidalee stores your League of Legends and VALORANT accounts on your own PC and logs into them for you. Pick an account, pick a game, hit launch: Nidalee starts the Riot Client, fills in your credentials, waits out any game update, and launches the game. Switching from one smurf to another takes a couple of seconds instead of a trip to your password manager.
It is a 2 MB native Windows app built with Rust and Tauri. There is no account to create, no server, and nothing to sync.
💕 Accounts
- Unlimited accounts for League of Legends and VALORANT
- One-click auto login into the Riot Client
- Categories for grouping accounts (mains, smurfs, regions, whatever you like)
- Last login tracking per account
- Automatic detection of a running game, with the option to close and switch
💕 Launching
- Finds your Riot Client automatically via the registry, common install paths, and a drive scan
- Waits for client and game updates to finish before logging in
- Up to five launch attempts, each verified against the running process list
- Adjustable login delay for slower machines
💕 System integration
- Start with Windows, optionally minimised
- Minimise to tray, and on game launch
- Remembers which monitor you left it on
- Single instance: launching again focuses the existing window
💕 Privacy
- Credentials encrypted at rest with the Windows Data Protection API, scoped to your Windows user
- Everything stays in
%APPDATA%\Nidalee, nothing is uploaded - Zero analytics and zero telemetry
- In-app updates, signed and verified against a key baked into the app
Download the latest installer and run it:
⬇ Download Nidalee for Windows
Windows may warn you that the publisher is unrecognised, because the installer is not code signed yet. Choose More info then Run anyway. From this version onward, Nidalee updates itself: it checks nidal.ee on launch and installs signed updates with your confirmation.
- Open the Add Account tab and save your first account
- Go to Main, choose the account and the game
- Hit Launch Game
While logging in, don't switch windows or move the mouse. Nidalee types your credentials into the Riot Client the same way you would, so anything that steals focus can receive those keystrokes.
Accounts live in %APPDATA%\Nidalee\accounts.json. Usernames and passwords are encrypted with
Windows DPAPI, which derives the key from your Windows user account, so the file is useless when
copied to another machine or read by another user.
That protects against a stolen file, not against malware running as you: anything with your user token can ask Windows to decrypt it, exactly as Chrome's saved passwords work. Keep your machine clean, and enable two-factor authentication on your Riot accounts.
Versions up to and including 0.1.3 stored credentials in plaintext. If you used one of those, update and change any password you would rather not have had sitting in a readable file.
Nidalee is an independent, unofficial project. It is not affiliated with, endorsed by, or approved by Riot Games. League of Legends and VALORANT are trademarks of Riot Games, Inc.
Nidalee types your own credentials into Riot's official client. It does not touch the games, read game memory, or give any competitive advantage. It is still third party automation that Riot has not approved, so use it at your own discretion and read the terms.
Requires Node.js 18+, Rust, and the Visual Studio C++ build tools.
