Lichess Lag Analytics

Tracks network latency, provides post-game analysis via API, and correlates lag with win rates.

Lichess Lag Analytics is built for players who care about one thing: converting better play into better results, especially in fast time controls where milliseconds matter. This extension tracks your real in-game connection behavior on lichess.org (ping, jitter, spikes, and time loss), then turns it into practical chess insights. Instead of generic “your up to 500ms connection is good,” you get game-by-game evidence of how latency impacted your clock, your decisions, and your results. Key features: – Live in-game ping monitor with quick traffic-light indicator (green/yellow/red). – Per-game lag graph and packet-loss/time-loss tracking. – Recent games dashboard with detailed single-game analysis. – Ping vs Win Rate correlation (including rated/casual splits). – Opponent lag/compensation tracking and opponent history pool. – Match Guard tools to help avoid consistently high-lag pairings (with safety controls). – Jitter stats and trend views for your last games. – Backup/import of extension data. – Hybrid sync mode for lightweight settings across devices. – How it can improve rating: Helps you identify whether losses are tactical mistakes, time pressure, or network instability. Lets you tune your setup (Ethernet, browser load, routing choices) using measurable feedback. Makes time controls more intentional: strict settings for Bullet, different thresholds for Blitz/Rapid. Reduces avoidable flag losses by improving connection consistency, not just average ping. Builds long-term connection awareness so your practical playing strength matches your actual chess strength. Scope: Works on lichess.org and focuses on connection/performance analytics, not engine analysis. Gives strong practical signal for online performance optimization, especially Bullet/Blitz.
