This is a safe product simulation.

The interactive preview uses fictional sample statistics, achievements, and community boards. It makes no Riot API calls, Discord posts, or real account connections. The Windows desktop client uses your own supported League history.

Built for understanding

Useful information, without dashboard clutter.

MayhemLab keeps the signal close to the action: what changed, where you perform best, what separates your wins from losses, and what is worth reviewing next.

◇

Game Labs

Separate analysis for Normal Rift, Ranked, League Classic reference, ARAM, ARAM Mayhem, and Arena. Each mode uses metrics that actually make sense for that mode.

Mode-aware analytics
↗

Ranked Climb Lens

Track role commitment, champion-pool focus, last-10 form, death baseline, lane fundamentals, and the differences between your own ranked wins and losses.

Personal improvement signals
⌁

Intelligence Feed

Surfaces meaningful changes such as Hot Hand runs, personal records, patch shifts, repeat encounters, and build associations when your own sample supports them.

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.
