Yes, security is a priority. Authentication via Discord OAuth2 (no passwords stored). The site is protected by strict security headers (HSTS, CSP, X-Frame-Options), rate limiting on all API routes, and parameterized SQL queries against injections. Communications are encrypted via HTTPS. GDPR compliant with right to delete and export your data.

The site runs on Next.js 16 (React 19) with strict TypeScript (0 @ts-ignore across 137,000 lines), Node.js 22, PostgreSQL via Prisma ORM with PgBouncer, and Redis cache. Hosting uses PM2 in cluster mode (4 instances) behind Nginx with Brotli. AI coaching relies on Anthropic's Claude API with prompt caching (-90% cost). Monitoring is handled by Sentry. The code is tested (961 unit and E2E tests) and linted (0 errors, 0 warnings) with an automatic CI/CD pipeline.

All data comes from the official Riot Games API. Our automatic collector continuously gathers thousands of ranked matches to feed stats, tier lists and builds.

Profiles: on each visit. Leaderboard: every 2h. Builds and tier lists: daily. Patch notes: with each new patch.

10 regions: EUW, EUNE, NA, KR, JP, BR, TR, RU, LAN and LAS.

By comparing your performance to the averages of your rank and role on each metric (KDA, CS/min, vision, gold, damage…). S = top of your elo, D = well below.

If you haven't played recently or your account is new, the Riot API only provides recent ranked matches. The more you play, the more complete your profile will be.

A real-time chat right on the site, Discord-style: topic channels, online member list, markdown, emojis, @mentions and private messages between players. Fully self-hosted (no third-party service) and encrypted at rest. No install required.

LegendsTracker stays free; the subscription is an optional way to support us that raises your daily AI analysis quota and grants you a dedicated role on our Discord. Members of the Legends Path Discord get premium access for free. Your status syncs automatically after payment or verification.

Every champion has a build recalibrated to its actual kit: item order and the reasons (the tooltips) are computed from its damage type, scalings, on-hit effects, %HP, crit, mana reliance and ability resets, then checked against the patch's official stats. For heavily-played champions, the real Emerald+ build (with win rate) takes over once the sample is large enough. A guard prevents any inconsistent build, such as two items from the same exclusive group (e.g. two Hydras).
