Personal, not prescriptive
Your own history is the model.
MayhemLab is designed to help players understand their play rather than dictate decisions. It compares you with you, separates modes where the comparison matters, and keeps live information inside the boundaries of what is already available to the player.

FAQ
Reasonable questions.
Is MayhemLab an official Riot Games product?
No. MayhemLab is an independently developed third-party companion. It is not endorsed by Riot Games.
Does MayhemLab make decisions for me during a match?
No. The product is built around personal context, static references, visible live-client information, and post-match analysis. It is not designed to expose hidden information or automate competitive decisions.
Does MayhemLab require a Riot API key from every user?
The goal for a production release is no. Riot API requests that require a production key will be routed through a secured MayhemLab service after approval; the production key will not be distributed inside the desktop app.
Why is League Classic different?
MayhemLab treats Classic primarily as a reference/build workspace because it does not fabricate unsupported public personal match-history aggregation.
What changed in the latest release?
The Trophy Vault adds rotating weekly objectives, class mastery milestones, community records, daily leaderboards, seasonal recognition, and dedicated Discord channels. See all releases ↗
Do I have to link Discord or share my history?
No. Personal analysis remains available locally. Community features require an optional Discord link and user-enabled sharing categories. Competition results are submitted by linked desktop clients and are not independently Riot-verified.
Where can I get support?
Join MayhemLab HQ on Discord for setup help, bug reports, feature requests, and release announcements.
