League of Legends overlays that run in the game, with and without Overwolf. Not stream overlays.
There is no single best overlay; it depends on what you want to see during a game. Porofessor and Mobalytics show the most, with jungle timers, gold leads and build trackers, but both carry ads in their free versions and Mobalytics needs Overwolf. Blitz, OP.GG Desktop and U.GG run without Overwolf, also with ads in their free versions, and each lists an ARAM Mayhem augment overlay.
If you only want the scoreboard per lane, light and without ads, LazyElo's overlay does that. It is part of Plus. This page covers overlays inside the game; a stream overlay for OBS or Twitch is a different kind of product.

Checked October 29, 2026; the Porofessor and Mobalytics rows come from our sourced comparisons of October 26, 2026. Written by the maker of LazyElo, so read it as one side's view. Claims one app makes about another say so, and where we found nothing we say that instead of guessing.

Worth a look if you want a native app and play only a few games a day.
Hexgate describes itself as a native app built with Tauri and Rust, without Overwolf, free for 3 games a day, with Pro at €9.99 a month. We haven't checked its overlay in detail.
Worth a look if you want summoner timers without Overwolf.
Its overlay page lists Flash and enemy summoner timers and gold per lane, without Overwolf. We haven't checked it in detail.
Of the eight, Blitz, OP.GG Desktop, U.GG, Hexgate, Buildzcrank and LazyElo run without Overwolf, and Porofessor can since December 2025. Mobalytics needs it.
Without Overwolf doesn't mean light. Blitz, OP.GG Desktop and U.GG are Electron apps, which bring a browser engine along, says Hexgate, and the standalone Porofessor is built on Electron too. LazyElo is a native Windows app; what it measured on its own PC is below.

LazyElo's overlay shows each enemy's ult cooldown at their current level as a fixed number from the patch data. It never counts down and never tracks when an ult was used. More on what Riot allows, app by app, on Are LoL apps safe?
Three places
Your size, your see-through
Out of your way
The overlay is part of Plus (€4.99 a month or €39 a year). Every new account gets 7 days of Plus free, without a payment card. The full overlay page: LoL overlay without Overwolf.
What LazyElo asks of your PC: first what follows from how it is built, then what we measured. We only put a number here once we have measured it.
Native, without Overwolf
A Windows app of its own. No Overwolf and no browser engine running next to your game.
No ads
Nothing in the app loads ads or ad videos, in the lobby or during a game.
A small overlay
The overlay is a separate see-through window. It only draws scoreboard info and redraws twice a second.
Nothing inside the game
LazyElo reads the client and the game's own live data through the local connections Riot provides. It never runs inside the game process and never reads game memory.
