League apps without Overwolf: what still needs it, what doesn't

“Electron” means the app ships a browser engine of its own; “native” means it doesn't. Neither says how much memory an app uses: the only published figures are iTero's (a rival) for Porofessor, about 1,000 MB in a game with Overwolf, and Mobalytics, about 1,400 to 2,000 MB, and our own for LazyElo further down. The app roundup with sources compares the same apps on what they do.

• Porofessor, standalone

  The standalone build of December 5, 2025 drops the Overwolf client but not Overwolf itself: the press release says Overwolf “remains M.O.B.A.'s ad monetization and tech partner for all in-game apps”. So you keep the lobby scouting, the timers and the ads, on Electron instead of Overwolf. Premium removes the ads; its price isn't on the site.

• Blitz

  Blitz never needed Overwolf. You get one-click rune and build import, pick and ban tips, a jungle pathing overlay and camp timers, and ads in the free version that users describe as autoplay video. Premium is $4.99 a month or $3.33 billed yearly. What you give up: nothing from Overwolf, but Electron brings a browser engine along.

• OP.GG Desktop

  An Electron app, 84 MB by Warden's count, with “a range of in-game overlays”, an AI Agent that talks during matches, and a macOS version, the only one in this list. Ads in the free version, says Hexgate. What you give up: a public response to Riot's October 2026 notice; we found none.

• U.GG app

  Electron, next to the u.gg website: champ select scouting, rune and build import by rank, role and matchup, a live stat tracker and a Carry Score after the game. Ads in the free version; U.GG Plus is $3.99 a month or $2.49 billed yearly.

• Hexgate

  Hexgate describes itself as a native app built with Tauri and Rust, free for 3 games a day with Pro at €9.99 a month. It is also the rival whose comparison pages rank for most no-Overwolf searches, so read its grouping of other apps as a competitor's claim; we cross-checked the rows above against the vendors' own pages where they load.

• Warden

  Khaos Studio says Warden is a 26 MB native app without ads, in beta. We haven't checked it ourselves, and its page is a vendor page that also ranks other apps, so treat its figures the same way as Hexgate's.

• iTero

  iTero sells itself as an AI coach, and its own article (March 2026) is the source of the Porofessor and Mobalytics RAM figures you see quoted around the web. Whether it has a build without Overwolf isn't stated in the sources we checked, so it sits in the table with question marks rather than a guess.

• LazyElo

  A native Windows app without Overwolf or a browser engine, no ads in any plan, and it never clicks, picks, locks or imports for you. We measured 428 MB of RAM idle in the lobby and 511 MB during a game with the overlay on at 0.0% CPU. An FPS test with and without LazyElo is still in progress, so we make no FPS claim yet. What you give up: rune import (it shows runes, you set them), timers and alerts (none, by design), and a Mac version (Windows 10 and 11 only).

• Native, no browser engine

  A Windows app of its own, 50 MB to install. No Overwolf client, no Electron.

• No ads, in any plan

  The free plan has no ads and no end date; Plus and Pro add features, not ad removal.

• It never clicks for you

  No rune or build import, no auto-accept, no picks or locks. It shows; you decide.

• Measured, with version and date

  We measured 428 MB of RAM idle in the lobby and 511 MB during a game with the overlay on at 0.0% CPU. An FPS test with and without LazyElo is still in progress, so we make no FPS claim yet.

• Honest limits

  No rune import, no timers or alerts, no Mac version. What it does show during a game is on what the overlay shows; how that compares with the others, on which overlay shows what.
