LoL Overlays Without Overwolf: Which Apps Run Standalone, and Which Do Not

Short answer: Blitz, OP.GG Desktop, U.GG, and Hexgate all run without Overwolf. Porofessor and Mobalytics do not: both are Overwolf apps, and they need the Overwolf host running underneath them. If you want to skip Overwolf entirely, you are choosing between two standalone Electron apps (Blitz and OP.GG), a build importer with no in-game overlay (U.GG), and one native app (Hexgate, which we build, so weigh our ranking accordingly).

The rest of this guide covers what Overwolf actually is, why so many players search for a way around it, and which no-Overwolf option fits what you need. There is also a section for TFT players, because the answer there is different.

Every Major LoL Overlay, Classified

App	Runs on Overwolf?	Runtime	Best for
Hexgate	No	Native (Tauri/Rust)	Adaptive builds, lightest footprint
Blitz	No	Standalone Electron	All-in-one, multi-game incl. TFT
OP.GG Desktop	No	Standalone Electron	Stats platform in the client, TFT
U.GG	No	Standalone app (no in-game overlay)	Fast meta build imports
Porofessor	Yes	Overwolf app	Live game scouting
Mobalytics	Yes	Overwolf app	Coaching and post-game analysis

The "Runtime" column is the one most comparison articles skip, and it is the one that decides how the app feels on your machine. Three runtimes show up in this list, and they cost very different amounts.

What Overwolf Actually Is, and Why People Avoid It

Overwolf is a host platform. It is a desktop application that other apps run inside of, the way browser extensions run inside a browser. Developers publish their overlay to Overwolf's app store; you install Overwolf first, then install Porofessor or Mobalytics as an app within it. Overwolf handles the in-game overlay layer, the updates, and, on free apps, the advertising.

That arrangement has real upsides, which is why it has survived so long. One launcher covers many apps across many games, so a player who runs an Overwolf app for another title gets Porofessor almost for free. Updates arrive through one pipeline. Developers do not have to build and maintain their own overlay injection, which is exactly the kind of thing small teams get wrong. And Overwolf apps have a long track record of staying within Riot's rules.

The reasons players search for "overlay without Overwolf" are just as concrete:

• Two processes instead of one. You are running Overwolf as the base layer plus the app on top of it, alongside League itself, Discord, and a browser. Our Mobalytics comparison puts the combined footprint in browser-engine territory, with reported memory around 1,400 MB and spikes toward 2,000 MB during games.
• Ads come with the platform. Free Overwolf apps are ad-supported, and the reviews we cite for both Porofessor and Mobalytics describe the ad load as aggressive. Paying the app's subscription removes them, but you are paying to remove something the runtime added.
• An extra thing that must be running. If Overwolf is closed, crashed, or mid-update, the overlay is gone. Players on older machines have been complaining about Overwolf overhead for years, and it is the single most common reason people look for Porofessor alternatives.

The catch is that "no Overwolf" does not automatically mean "lightweight". The standalone alternatives split into two very different camps:

Electron apps (Blitz, OP.GG Desktop) ship their own Chromium engine inside the app. You get one process instead of two, no host dependency, and no platform ads, but you still carry a browser engine's worth of memory. Blitz in particular has a public history of high RAM usage after long sessions, and Blitz itself acknowledged frame drop and stuttering issues in a statement before improving things.

Native apps (Hexgate, built with Tauri and Rust) use the webview already built into Windows instead of bundling one. The result is a footprint typically under 100 MB with negligible CPU cost. If the reason you are avoiding Overwolf is performance, this is the category that actually solves it; if the reason is the host dependency or the ads, Electron apps solve those two just fine.

The No-Overwolf Options, Ranked

Ranked by what each app is genuinely best at, with the tradeoffs stated plainly. We build number one, so read that entry with the appropriate salt.

1. Hexgate - Lightest Footprint and Adaptive Builds

Hexgate is the only native app in the list: Tauri and Rust, no Overwolf, no Electron, typically under 100 MB of memory, no ads on the free tier. If your goal in avoiding Overwolf is to get the overlay overhead as close to zero as possible, nothing else here comes close.

It is also the only one that does something different with builds. Every other app on this page hands you the aggregate build for your champion this patch, the same one every other player of that champion gets. Hexgate reads the enemy team from Riot's Live Client Data API during the game and re-scores every viable item against them. Core early items stay pick-rate driven, so you are never handed something weird for your first buy; the situational slots adapt to the enemy damage split, crowd control, healing, shields, tankiness, and fed threats. Every comp-driven nudge is labeled with the reason in the overlay, so you can see why armor moved up against four AD threats or why anti-burst moved up against a 7/0 assassin. Counter-building is the one skill it automates.

The rest of the package: one-click rune import on the free tier, and Pro adds lane matchup scoring and OTP (one-trick) builds. Free covers 3 games per day; Pro is 4.99 EUR per month, or 3.74 EUR per month billed annually.

The tradeoffs: Windows only, LoL only (no TFT, no Valorant), no player scouting, no jungle timers, no post-game analytics. It does one job. If you want the everything-app, it is not this one.

2. Blitz - Best All-in-One Without Overwolf

Blitz is the standalone answer to "one app for everything". Automatic rune and build import, jungle timers, ultimate tracking, teammate summoner spell timers, post-game analysis, performance tracking, and a loading screen overlay that shows each player's rank, win rate, recent performance, and most played champions. That last part matters for this article: it is the closest thing to Porofessor's scouting you can get without installing Overwolf.

It also covers League, TFT, Valorant, and several other games in one install, and it supports Windows and macOS (the overlay features are Windows only).

The tradeoffs: it is an Electron app, and its memory footprint is the most discussed of any app on this list. The free tier carries ads and upsells, with users reporting autoplay video ads and pop-ups. And its builds are static aggregates: the same recommendation for every player of your champion, regardless of the enemy team. Full comparison in Hexgate vs Blitz vs Mobalytics.

3. OP.GG Desktop - Best Stats Platform Without Overwolf

OP.GG is the reference stats site for the entire player base, and its desktop app is a standalone Electron application that brings that data into the client: automatic rune and build import in champ select, a Shift+Tab in-game overlay with builds, opponent data, and spell timers, plus TFT and Valorant support. It is free, familiar, and runs on Windows and macOS.

If you already live in OP.GG's profile pages, this is the least disruptive no-Overwolf pick. The rune import alone saves the fumbling minute before lock-in, and the opponent data in the overlay is useful even if it is shallower than a dedicated scouting tool.

The tradeoffs: Electron footprint, the platform's advertising on the free experience, and every recommendation is a patch-level aggregate that ignores your actual lobby. Details in Hexgate vs OP.GG.

4. U.GG - Simplest Build Imports Without Overwolf

U.GG's app does one thing with no ceremony: it detects your champion in select and imports the highest win rate runes and item sets. No Overwolf, no subscription, fully free, on Windows and macOS. For a player whose entire requirement is "give me the meta build without alt-tabbing", it is the least friction of anything here.

The tradeoffs: it is not an in-game overlay in any meaningful sense. There is no live overlay reading your game state; once the loading screen ends, U.GG's job is done. It also has no scouting and no analysis, and the builds are the same static aggregates as everywhere else. If you searched for "overlay without Overwolf" because you want something on screen during the game, U.GG is not that; it belongs on this list because it is a legitimate Overwolf-free way to get builds into the client. More in Hexgate vs U.GG.

What You Give Up by Skipping Overwolf

Honesty cuts both ways. Two of the best tools in the ecosystem are Overwolf-only, and no standalone app fully replaces either.

Porofessor is still the best live game scouting tool: ranks, win rates, playstyle tags, loss streaks, and one-tricks for all ten players, surfaced automatically in champ select, backed by the League of Graphs team. Blitz's loading screen overlay covers the basics of this, but Porofessor's version is deeper and better known. If scouting is what decides your games, Overwolf is part of the price. Our Hexgate vs Porofessor comparison goes through exactly that decision.

Mobalytics owns post-game analysis. Its GPI breaks your play into measurable skills and is the most serious attempt in the ecosystem at telling you why you lost. The in-game overlay is not the star; the analysis after the game is. Nothing in the no-Overwolf list does this at the same depth.

One reasonable setup, if your machine can afford it: keep an Overwolf app for the pre-game or post-game half, and run a native overlay in-game. Porofessor for scouting plus Hexgate for itemization overlap almost nowhere.

If You Need TFT

Hexgate does not support Teamfight Tactics. It is a League of Legends only tool, and the reason people search "TFT overlay without Overwolf" is a problem it cannot solve. Do not install it for TFT.

The apps on this page that our comparisons list as supporting TFT are Blitz, Mobalytics, and OP.GG Desktop. Of those, Blitz and OP.GG are the two that run standalone without Overwolf, so they are the TFT answer to this article's question. Mobalytics covers TFT as well but runs on Overwolf, so it does not qualify.

A Note on Riot Safety

Whether an overlay uses Overwolf, Electron, or a native runtime has nothing to do with whether Riot allows it. Riot's third-party tool policy is about behavior: reading public data or Riot's local APIs is fine; modifying game files, reading game memory, or automating inputs is not. Every app in this article, on both sides of the Overwolf line, operates within those rules. Hexgate specifically reads the Live Client Data API that Riot provides locally during active games and writes rune pages through the same League client API that Blitz, OP.GG, and U.GG use. The tools that get accounts banned are the ones promising scripting or automation, and none of them are on this page.

How to Pick

• You are avoiding Overwolf because of RAM or FPS: Hexgate. It is the only native option, and the only one that actually fixes the overhead rather than halving it.
• You are avoiding Overwolf but want one app for everything: Blitz. Accept the Electron footprint and the ads.
• You want OP.GG's data in your client: OP.GG Desktop.
• You just want the meta build imported and nothing on screen: U.GG.
• You play TFT: Blitz or OP.GG. Not Hexgate.
• You build the same items every game no matter the enemy comp: Hexgate, because the runtime is a bonus and the adaptive builds are the point.

FAQ

Does Blitz use Overwolf?

No. Blitz is a standalone Electron app. You install it directly and its overlay works without a separate host platform like Overwolf. The tradeoff is that Electron still bundles a browser engine, so Blitz carries a real memory footprint of its own, and the free tier is ad-supported.

Does Porofessor need Overwolf?

Yes. Porofessor runs as an Overwolf app, so Overwolf has to be installed and running as the host platform underneath it. There is no standalone Porofessor overlay. If you want its live game scouting, Overwolf is part of the price; if you want to avoid Overwolf, Blitz covers loading-screen scouting in a standalone app.

Does Mobalytics work without Overwolf?

The Mobalytics desktop app and its in-game overlay run on Overwolf, so no, the overlay does not work without it. You need Overwolf as the base layer and Mobalytics on top, which is two processes alongside League. Its post-game analysis and GPI are the main reasons players accept that overhead.

Is there a TFT overlay without Overwolf?

Yes. Blitz and the OP.GG desktop app both support TFT and both run standalone without Overwolf. Mobalytics also covers TFT but runs on Overwolf. Hexgate does not support TFT at all: it is a League of Legends only tool, so TFT players should look at Blitz or OP.GG.

Are overlays without Overwolf allowed by Riot Games?

Yes. Riot's third-party tool policy is about what an app does, not what runtime it uses. Blitz, OP.GG, U.GG, Hexgate, Porofessor, and Mobalytics all read publicly available data or Riot's local APIs, and none of them modify game files, read game memory, or automate inputs. Overwolf or not, none of these apps will get you banned.
