The 6 Best LoL Overlays in 2026, Ranked by What They Actually Do Best
"Best overlay" is the wrong question - each of these apps wins a different category. Here is what each one is genuinely best at, what it costs you in money and RAM, and how to pick.
Full disclosure: we build Hexgate, one of the six apps below, and we put it first. Every other entry is written to be useful anyway, including where a competitor is simply the better choice and who should skip Hexgate.
Quick Picks
Each app here is the best in the League ecosystem at something. Find the line that sounds like you and jump straight to it.

Hexgate Best Adaptive In-Game Itemization
Ours, so apply salt. Hexgate exists because of the pattern you will notice in every entry below: every other app in this list recommends the aggregate build, the one computed across all games this patch, with no knowledge of who you are actually playing against. Hexgate reads the enemy team live and re-scores every viable item against their damage split, crowd control, healing, tankiness, and fed threats. Against four AD threats it moves armor up. Against a 7/0 Katarina it moves anti-burst up. Each adjustment is labeled with the reason, so you learn the counter-build logic instead of just copying it.
What it does best
- Keeps re-ranking your next item through the whole game, against the lobby you are actually in.
- Shows why: every move comes with a tag like Heavy AD and the enemies behind it. Counter-building is the one skill it automates.
- The lightest app in this list: no Overwolf, no Electron, no ads.
- Real ARAM Mayhem augment support: live S–D tier badges on the augment cards as they are offered, plus a Mayhem champion tier list in champ select.
- Each lane's gold difference on League's own scoreboard while you hold Tab, with both team totals: the gold gap League itself only shows in spectator mode and replays. Free.
- With Pro+: a post-game Match Breakdown of every ranked, Draft and Swiftplay game, Lane Scouting on the loading screen (the early-game habits of your lane opponent and the enemy jungler) and Clips of every death to rewatch.
The tradeoffs
- No player profiles or rank lookups for the whole lobby.
- Windows only, and the free tier is 3 games per day. If you want breadth, pair it with the OP.GG website or pick Blitz instead.
Zed and Kha'Zix on the enemy team: Zhonya's Hourglass jumps to first for Ahri's 3rd item, tagged Heavy AD.
Akali and Malphite on the enemy team: Mercurial Scimitar leads Jinx's 5th item, tagged Heavy AP.
Diana, Mordekaiser and Syndra on the enemy team: Kaenic Rookern leads Leona's 3rd item and the boots switch to Mercury's Treads.
Sivir on the enemy team: Guardian Angel and Death's Dance move to the top of Vi's 3rd item and the boots switch to Plated Steelcaps.
Why we would pick it over the rest
The apps below hand you a build before the game; after that, the item shop is up to you. Hexgate keeps making item decisions with you at 18 minutes, when the enemy Katarina is 7/0 and the aggregate build has no answer. If your losses come from building the same items every game, this is the leak to close first. If your losses come from drafting blind, keep reading: Porofessor is better at that. For mistakes you cannot see, compare Mobalytics with Hexgate Pro+'s Match Breakdown, which explains every ranked game you play.
Blitz Best All-in-One for Most Players
Blitz is the default answer when someone asks for "an app for League". Auto rune import, build suggestions, post-game stats, benchmarks, and coverage of multiple games in one package. It gets the fundamentals right with minimal setup, which is exactly what most players want.
The tradeoffs
- An Electron app with a real memory footprint.
- The free tier carries ads and upsells.
- Its build recommendations are aggregate meta builds: the same for every player of your champion, regardless of the enemy team.
- Breadth is the product; no single feature is the deepest of its kind.
Mobalytics Best for Improvement and Analysis
Mobalytics is the improvement platform of the group. Its GPI (Gamer Performance Index) breaks your play into measurable skills, and the post-game analysis is the most serious attempt in the ecosystem at telling you why you lost, not just that you did. If you treat ranked like a sport and want a training tool, this is the category winner.
The tradeoffs
- The good parts sit behind the Plus subscription.
- It runs on Overwolf, a second platform alongside League.
- The in-game overlay itself is not the star - the analysis after the game is. Builds, again, are static aggregates.
Porofessor Best Live Game Scouting
Porofessor answers one question better than anyone: who is in this lobby? Ranks, win rates, playstyle tags, loss streaks, one-tricks - surfaced automatically in champ select. Knowing the enemy top is autofilled or their ADC is smurfing changes real decisions, and Porofessor makes that information effortless. Backed by the League of Graphs team, the underlying data has a long track record.
The tradeoffs
- It was Overwolf-only until its standalone app arrived in December 2025.
- The free tier is ad-supported.
- It is fundamentally an information tool: it tells you the enemy mid is fed, not what to do about it.
OP.GG Desktop Best Stats Platform Integration
OP.GG is the reference stats site of the entire player base, and the desktop app moves that into the client: auto 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. Free, familiar, and the data everyone already argues from.
The tradeoffs
- Electron footprint and ads.
- Every recommendation is a patch-level aggregate that ignores your actual lobby.
U.GG Best Simple Build Imports
U.GG built its reputation on being the fastest, cleanest place to grab the highest win rate build and runes, and its app does exactly that with no ceremony. If your entire requirement is "give me the meta build without alt-tabbing", U.GG delivers it with the least friction of anything here, for free.
The tradeoffs
- The free site and app show ads; U.GG Plus removes them.
- It tells you what wins rather than why you lost.
- Its builds, though filterable by rank and lane matchup, are the same kind of pre-game aggregate as everywhere else.
How to Actually Choose
Ignore feature counts and ask what loses you games:
- You get outdrafted or surprised by smurfsPorofessor
- You repeat the same mistakes and cannot see themMobalytics
- You just want the meta build and runes, fastU.GG, or OP.GG
- You want one app that covers the basics everywhereBlitz
- You build the same items every game no matter the enemy compHexgate
That last one is the leak Hexgate exists to close. We compared every popular LoL build app on exactly that question.
On performance: everything Overwolf-hosted or Electron-based costs a browser engine of RAM. With 16 GB or less, pick one heavy app at most, or pair light tools that each do one job.
Safety, Briefly
All six apps operate within Riot's third-party tool policy:
- Public data and Riot's local APIs only
- No memory reading
- No injection
- No input automation
None of them will get you banned. The tools that do are the ones promising scripting or automation, and none of them are in this list. Riot's rules have changed four times since 2025, most recently on October 6, 2026; our guide on whether you can get banned for LoL apps quotes them directly.
FAQ
Are LoL overlays allowed by Riot Games?
Yes, as long as they follow Riot's third-party tool policy: reading only publicly available data or Riot's local APIs, no game file modification, no memory reading, no input automation. Every app in this roundup - Blitz, Mobalytics, Porofessor, OP.GG, U.GG, and Hexgate - operates within those rules. Tools that script, automate inputs, or read memory are the ones that get accounts banned.
Do overlays hurt FPS in League of Legends?
The overlay UI itself rarely does, but the app hosting it can. Electron apps and Overwolf-hosted apps each add a browser engine's worth of memory. On 16 GB machines running League, Discord, and a browser, that overhead is noticeable. Native apps like Hexgate (Tauri/Rust) keep the footprint under 100 MB.
What is the best free LoL overlay?
All six apps in this roundup have usable free tiers. Blitz and OP.GG offer the most complete free feature sets (with ads), Porofessor offers full scouting free (with ads), U.GG is free (with ads), and Hexgate's free tier covers 3 games per day with no ads. The best one depends on which problem you want solved, not which is cheapest.
Can I run more than one overlay at once?
Yes. Common pairings combine tools that do not overlap, like Porofessor for pre-game scouting plus Hexgate for in-game itemization. Watch two things: total memory footprint, and features that conflict, like two apps both trying to auto-import runes.
