If you play League of Legends in 2026, you have probably used a companion app at some point. Blitz, Mobalytics, Porofessor, U.GG, OP.GG - the list keeps growing. These tools promise to help you climb by providing builds, stats, and overlays. But they are not all doing the same thing, and the differences matter more than most comparison articles admit.

This is a comparison between Hexgate, Blitz.gg, and Mobalytics - three overlay apps that take fundamentally different approaches to helping you build items. We built Hexgate, so we are obviously biased. But we will be upfront about what each tool does well and where each one falls short. You should pick the tool that matches how you want to play.

The Core Difference: Static Builds vs Adaptive Builds

Before comparing features line by line, it is worth understanding the philosophy behind each app, because that shapes everything else.

Blitz and Mobalytics are build importers. They look at what items have the highest win rate across all games for your champion, and they import that build into your item shop. The build is determined before the game starts. It does not change based on the five specific enemies you are facing. If the highest win rate Jinx build includes Infinity Edge into Rapid Firecannon, you get that build whether you are playing against five squishies or a triple-tank composition.

Hexgate is an adaptive build advisor. It reads the enemy team composition from Riot's Live Client Data API during the game and scores every viable item based on how well it performs against the specific enemies in your match. The recommendations update as you progress through item slots, factoring in damage types, crowd control, healing, shielding, and tankiness across all five opponents. You are not getting a generic best-case build. You are getting the build that counters what you are actually facing.

This is not a subtle distinction. The highest overall win rate build for a champion is the build that works best on average across thousands of games. But your game is not average. If the enemy team has three AP champions and your static build has no magic resist, you are leaving gold efficiency on the table that an adaptive build would have caught.

Blitz.gg - The Feature-Rich All-Rounder

What Blitz Does Well

Blitz is the most feature-complete companion app on the market. It covers League of Legends, TFT, Valorant, and several other games. For League specifically, Blitz offers automatic rune and build imports, in-game overlays with jungle timers and ultimate tracking, teammate summoner spell timers, post-game analysis, and performance tracking across your match history.

The breadth of coverage is genuinely impressive. If you want a single app that handles everything from champ select scouting to post-game review, Blitz is hard to beat. The UI is polished, the overlay works without needing a separate platform like Overwolf, and the data is pulled from a massive sample of ranked games.

Blitz's loading screen overlay is particularly useful. It shows you each player's rank, win rate, recent performance, and most played champions before the game even starts. This scouting information helps you identify which lanes are likely to be strong or weak, which can inform your early game decisions.

Where Blitz Falls Short

The main criticism of Blitz is performance overhead. Users have reported high RAM usage, with some seeing the app consume several gigabytes of memory after extended sessions. Blitz officially acknowledged frame drop and stuttering issues in a public statement, and while performance has improved over time, it remains a concern for players on lower-spec machines.

The other issue is advertising. The free tier includes ads, and users have reported autoplay video ads, pop-ups, and generally intrusive advertising that makes the free experience feel cluttered. Blitz Premium removes ads, but the free version can feel more like an ad platform with a companion app attached than the other way around.

On the build side, Blitz imports a single static build path. It is the statistically best build for your champion in your role, but it does not adapt to the enemy team. You get the same recommended items whether you are playing into a full AD team or a heavy AP composition. For players who already know how to counter-build, this is fine - you can ignore the import and build manually. But for players who rely on the app's recommendations, the lack of adaptive builds is a real gap.

Mobalytics - The Analytics Powerhouse

What Mobalytics Does Well

Mobalytics has the deepest analytics of any companion app. Its signature feature is the Gamer Performance Index (GPI), which breaks your gameplay into measurable categories like Farming, Fighting, Vision, Survivability, Aggression, and Consistency. Each category gets a score, creating a performance profile that shows your specific strengths and weaknesses.

The GPI is genuinely valuable for long-term improvement. It goes beyond "you won" or "you lost" and tells you why. Maybe your mechanics are fine, but your vision score is consistently low. Maybe you farm well in lane but drop off after 15 minutes. Mobalytics surfaces patterns that are hard to notice on your own, and it provides actionable advice for improvement.

The pre-game scouting tools are also strong. Mobalytics shows detailed breakdowns of your opponents, including their tendencies, champion pools, and recent form. The desktop overlay provides live insights during the game, including CS benchmarks, power spike timers, and objective reminders.

Where Mobalytics Falls Short

Mobalytics runs on the Overwolf platform, which means you need two applications running simultaneously - Overwolf as the base layer and Mobalytics on top of it. This has measurable performance consequences. RAM usage typically sits around 1,400 MB but can spike to 2,000 MB during games. If you are running League, a browser, and Mobalytics plus Overwolf on a machine with 16 GB of RAM or less, you will feel it.

The advertising situation is also aggressive. Recent reviews describe multiple simultaneous video ads playing in the lobby, banner ads taking up significant screen space, and pop-up ads at the bottom of the interface. The Plus subscription at $7.99 per month removes ads, but that is a significant monthly cost for a companion app.

Like Blitz, Mobalytics recommends static builds. The GPI and analytics features are excellent for post-game review and long-term development, but the in-game item recommendations follow the same highest-win-rate approach as every other major app. The build does not change based on the enemy team you are facing.

The overlay can also feel overwhelming. The sheer volume of data and widgets being displayed at once works well on large monitors, but players on laptops or smaller screens report that the overlay feels crowded and hard to parse at a glance.

Hexgate - The Adaptive Build Specialist

What Hexgate Does Well

Hexgate focuses on one thing and tries to do it better than anyone else: recommending the right items for the game you are in right now. Instead of importing a pre-game build, Hexgate reads the live game state, analyzes the enemy team composition, and scores items based on win rate data filtered by your champion, your build slot, and the specific enemies you are facing.

The scoring engine looks at multiple dimensions of the enemy team. It evaluates physical vs magic damage split, CC types and density, healing sources, shielding, and tankiness. If the enemy has three AP champions, items with magic resist are scored higher. If they have heavy healing, anti-heal items get a boost. If their team is full of auto-attackers, items like Frozen Heart score higher than they would against a caster-heavy composition. The recommendations are different every game because every game has a different enemy team.

Performance is minimal. Hexgate is a standalone Tauri application - no Overwolf, no Electron, no browser runtime. It runs as a lightweight overlay that sits on top of the game and uses virtually no resources. On most machines, you will not notice it is running.

It also includes one-click rune imports, champion select counter data (Pro), and OTP builds that show what one-trick players build on your champion (Pro). The rune import works the same as Blitz's - it writes the optimal rune page directly to the League client so you do not have to manually set it up.

Where Hexgate Falls Short

Hexgate is narrower in scope than Blitz or Mobalytics. It does not have jungle timers, ultimate tracking, teammate summoner spell tracking, post-game analysis, or performance analytics like the GPI. If you want a comprehensive dashboard that covers every aspect of gameplay, Hexgate is not that tool. It is focused specifically on itemization and build decisions.

The player scouting features are also more limited. Blitz and Mobalytics show detailed opponent profiles during loading screen with rank histories, champion pools, and win rates. Hexgate's focus begins when the game starts and the Live Client Data API becomes available.

Hexgate is also newer and smaller. Blitz and Mobalytics have been around for years with large teams, extensive documentation, and well-established communities. Hexgate is a smaller project that is still growing. That means fewer features today, though the core scoring engine is mature and backed by data from millions of ranked games.

Currently, Hexgate is Windows only. Blitz supports both Windows and macOS (though Blitz's overlay features are also Windows-only). If you are on Mac, Hexgate is not an option yet.

What About U.GG, OP.GG, and Porofessor?

These three deserve a brief mention since they are part of the wider ecosystem.

U.GG is one of the most trusted build sites for players who want clean, reliable data without clutter. Their overlay is straightforward and pulls builds from high-ranked and pro-level games. It is a great source for static builds, but like Blitz and Mobalytics, the builds do not adapt to the enemy team.

OP.GG is the gold standard for player lookup and match history. If you want to check someone's rank, recent performance, or champion stats, OP.GG is where most players go. Its companion app has improved significantly, but its strength remains in stats and scouting rather than in-game build guidance.

Porofessor was one of the first League overlays and has strong pre-game scouting tools. However, it requires Overwolf to run, and recent reviews point to increasing error reports and a user experience that is starting to feel dated compared to newer alternatives. Its scouting tool remains one of the better implementations available, but the overall package has not kept pace.

The Performance Question

Performance impact is a real concern for overlay apps, and it is one area where the differences are significant.

Blitz is a standalone Electron-based desktop app. Its resource usage has been a frequent topic of discussion, with some users reporting several gigabytes of RAM consumption after extended sessions. Blitz acknowledged this and has made improvements, but Electron applications inherently carry a higher baseline memory footprint than native apps.

Mobalytics runs on Overwolf, adding an extra layer. You are running Overwolf as the host platform plus Mobalytics on top of it, which means two processes sharing resources alongside League of Legends itself. Users on machines with less than 16 GB of RAM report noticeable impact.

Hexgate is built with Tauri, which uses a native webview instead of bundling an entire browser engine. The result is a significantly smaller memory footprint - typically under 100 MB. For players on older machines or anyone who notices performance dips with other overlays, the difference is tangible.

Why it matters: League of Legends itself is not particularly demanding, but many players run it alongside Discord, a browser, and a music app. Adding a companion tool that uses 1-2 GB of RAM on top of that stack can push lower-spec machines into frame drop territory. Lighter overlays leave more headroom for the game.

Safety and Riot Compliance

A question that comes up constantly: will using an overlay get me banned?

Riot Games has a clear policy on third-party tools. They allow applications that provide information a player could theoretically track manually - things like build stats, win rates, and scouting data. They prohibit applications that provide a measurable unfair advantage, such as exposing intentionally hidden information, automating gameplay actions, or altering the game's visual field.

In early 2025, Riot tightened the rules further by banning enemy ultimate ability alerts from overlays and deactivating the Spectator API to prevent player deanonymization. In mid-2025, they also banned in-game overlay advertisements. These changes affected all major overlay apps.

All three apps in this comparison - Hexgate, Blitz, and Mobalytics - operate within Riot's current guidelines. They use Riot's officially provided APIs and do not modify game files or inject code into the client.

Hexgate specifically reads from the Live Client Data API, which Riot provides at https://127.0.0.1:2999/liveclientdata/ during active games. This is a public local API that Riot designed for third-party tools. Hexgate does not interact with the League client in any other way - no file modifications, no memory reading, no packet interception. The rune import feature writes to the LCU (League Client Update) API, which is the same mechanism that Blitz and Mobalytics use to import rune pages.

Which One Should You Pick?

Honestly, the right answer depends on what you care about most.

Pick Blitz if you want everything in one app.

Blitz covers the most ground. Build imports, jungle timers, teammate tracking, post-game stats, and multi-game support. If you want a single install that handles champ select through post-game across multiple titles, Blitz is the most complete package. Just be aware of the resource overhead and the ads on the free tier.

Pick Mobalytics if you want to improve long-term.

The GPI system is the best performance analytics tool in the League ecosystem. If your goal is not just winning tonight but understanding your weaknesses and tracking your improvement over months, Mobalytics provides the deepest feedback loop. The cost is higher system requirements and a pricier subscription.

Pick Hexgate if you want smarter item builds every game.

If your primary frustration is that you build the same items every game regardless of what the enemy team is doing, Hexgate directly solves that problem. The adaptive scoring engine gives you builds that respond to your actual opponents, not a statistical average. It is also the lightest option if performance is a concern. The tradeoff is fewer features outside of itemization.

The Case for Adaptive Builds

We want to make one final point about why we built Hexgate the way we did, because it is not just a feature differentiator - it is a fundamentally different way of thinking about builds.

The standard approach to build recommendations, used by every major app, is to look at aggregate win rate data and recommend whatever wins the most games across all matchups. This is a reasonable starting point, but it has a blind spot: it treats every game as the same game.

A Jinx building Infinity Edge into Rapid Firecannon might have a 52% win rate across all games. But what is the win rate of that build specifically against a team with Malphite, Amumu, and Leona? Against that much hard engage and armor stacking, a different build path - maybe prioritizing Galeforce for mobility or Lord Dominik's for armor penetration earlier - might win significantly more often. The aggregate data hides this because it averages across all enemy compositions.

Counter-building is one of the highest-impact skills in League of Legends. The difference between building the right defensive item and the wrong one against a fed carry can be thousands of effective health points. Professional players adapt their builds every game. One-tricks with 60% win rates adapt their builds every game. The static "best build" is a simplification that works well enough most of the time but leaves real win rate on the table.

Hexgate's scoring engine exists to close that gap. It takes the same underlying win rate data that every app uses, but it filters it by the enemy composition in your actual game. The result is recommendations that shift based on what you are facing. Counter-building is the skill - Hexgate just automates the analysis that most players do not have time to do between recalls.

Final Thoughts

There is no single best overlay for everyone. Blitz, Mobalytics, and Hexgate each solve different problems. Blitz is the Swiss army knife. Mobalytics is the analytics platform. Hexgate is the itemization specialist. If you are reading this comparison, you probably care about builds - and if you care about builds, you should care about whether those builds adapt to what you are playing against.

The League overlay market has been dominated by apps that import static builds for years. We think there is a better way. Try Hexgate for free, build against what you are actually facing, and see if the difference shows up in your games. If it does not, Blitz and Mobalytics are both solid tools that will serve you well.

Whatever you pick, stop building the same items every game. Your enemies are different every game. Your build should be too.
