OP.GGvsMobalytics

Both show up when a player searches for "LoL stats", but they cover different needs. OP.GG is the de-facto match history tracker: enter a Riot ID and see rank, matches, per-champion stats, and current-patch tier lists, with no login or install. Mobalytics is a coaching platform built around the GPI (Gamer Performance Index), which diagnoses which areas you need to improve. Knowing when to open each one keeps you from using the wrong tool for the question you actually have.

What data each one offers

OP.GG is a lookup dashboard:

• Public profile with current and per-season historical rank
• Detailed match history (KDA, gold, vision score, every player's build)
• Per-champion stats and most-played picks
• Current-patch tier lists by role and rank
• Live Game and regional leaderboards

Mobalytics starts from the same data but reorients it toward improvement:

• GPI: a multidimensional score across 8 areas (combat, vision, farming, aggression, consistency, objectives, versatility, survivability)
• Comparison against players in your same rank and role
• Automatic per-match feedback ("high lane pressure but low team-fight impact")
• Builds and runes with pedagogical "why" notes
• Long-form coaching guides in its Academy section

The overlap is real (match history, builds, and tier lists appear in both), but the editorial angle is opposite: OP.GG describes, Mobalytics prescribes what to practice.

Entry friction and audience

OP.GG asks for no registration or install: go to the site, pick a region, paste the Riot ID, done. That makes it ideal for one-off lookups and for scouting other people's accounts in seconds. Its difficulty is beginner-level.

Mobalytics requires creating an account (login with Riot, Google, or Discord) and connecting your Riot ID before it shows the GPI, plus a few minutes to import matches. The 8 GPI areas take time to internalize, and with few analyzed matches (5-10) recommendations have low statistical confidence and feel generic; they improve with volume (50+). It's an intermediate-level tool meant for a player ready to invest in improving, not for glancing at a profile in passing.

Platforms, languages, and monetization

OP.GG runs on web, Windows, and macOS, with the broadest regional coverage in the ecosystem (Korea, NA, and EUW with huge datasets; smaller regions with more gaps in aggregates). It supports a dozen languages, Spanish included. It's free; there's a Premium tier (~$3/month) with filters and faster rendering, but 95% of the value is in the free version. It loads ads that can be annoying on mobile.

Mobalytics runs on web and Windows; the desktop app that assists in champ select requires the Overwolf runtime, with its own injected ads and telemetry (controversial in parts of the community). The web app has no such dependency. It supports several languages, Spanish included. The free tier covers basic GPI, builds, and dashboard; Mobalytics Pro (~$5/month) unlocks extended history and premium guides, with frequent upsells in the free version. The exact GPI formula is also proprietary, so it works as directional guidance rather than absolute ground truth.

Which one?

• Check your rank or a friend's fast → OP.GG. No login, straight to it.
• Scout an opponent in champ select → OP.GG. Paste the Riot ID and see their pool instantly.
• Pulse on the meta before a session → OP.GG. Per-role tier lists are one click away.
• Know the concrete area to work on to climb → Mobalytics. The GPI prioritizes it for you.
• Track whether your vision score improves week over week → Mobalytics. It keeps GPI history.
• Learn macro or vision by reading guides → Mobalytics. The Academy covers that; OP.GG doesn't.

They're complementary: OP.GG is the daily-lookup shortcut, Mobalytics is the diagnosis you follow once you decide to improve seriously. Many players keep OP.GG bookmarked and open Mobalytics when they stall in a rank.
