Desktop Companion

Private Beta · Current status: Private Beta (Registration pending)

A lightweight companion application that syncs champion select from your League of Legends client into KayLoL over local loopback (127.0.0.1) in real time.

Trust & Safety Guarantees

Official LCU Local Loopback

Connects strictly to Riot’s local League Client Update (LCU) HTTPS interface using the client lockfile. It does not touch memory, inject dlls, or inspect other processes.

100% Read-Only

Reads only the draft state already visible on your screen. It cannot and will not lock in champions, pick runes, or automate any game actions.

Loopback Only (127.0.0.1)

Draft state travels solely between the League client and your local browser tab over 127.0.0.1. Nothing about your live draft is transmitted to kaylol.gg to draw the board.

Riot Developer Policy Compliant

Built from the ground up to respect Riot Games third-party application policies and Vanguard integrity requirements.

Private Beta Registration

The desktop companion is currently under private beta evaluation while developer registration with Riot Games is finalized.
