League companion apps

The best League of Legends companion apps.

Five League of Legends companion apps, what each one costs you in ads or subscription, and which ones make you install a platform to get at them. Warden is the one we make, and we've flagged it where it comes up.

01 What you're actually choosing between

Every League of Legends companion here does the same core thing, Warden included. You lock in, and it puts the right runes, items and summoner spells in front of you without making you open a browser. That part is solved. It's been solved for years.

What differs is what each one wants back. One shows you ads. One puts the high-elo builds behind five dollars a month. Two install a second piece of software to run at all. That's the real comparison, so that's the one below.

Figures come from each app's own store page or site, checked August 2026, and cover the champ select job: getting the right runes, items and augments in before the loading screen. Overwolf-hosted installers pull the Overwolf platform down with them, so the listed size is the installer rather than the finished footprint.

03 What comes with each one

Blitz

The best known of the five, and the one that charges for the part you came for. Blitz imports runes and builds on lock-in and spans a stack of other games. The free version carries ads and the general-population builds. The Masters+ builds, the ones actually worth copying, live in Premium at $4.99 a month. Full breakdown in Warden vs Blitz.

Porofessor

The heaviest of the five. It reads the draft and scouts the lobby, and to get any of it you install the Overwolf platform alongside the app. The free tier carries ads, with Premium to switch them off. Its standalone build is listed at 100.8 MB, close to four times Warden. Compared in detail here.

Mobalytics

An analytics product with a build tool attached. The reports and rank tracking are what you're really installing, and champ select sits on top of them. Another Overwolf app, another ad-supported free tier with a Plus tier to remove them. Compared in detail here.

OP.GG

The website, in a window. It auto-sets runes and items and skips Overwolf, which is the one thing it and Warden agree on. What it doesn't skip is Electron: 84 MB of browser engine to draw a list of item icons, with ads in it. Compared in detail here.

Warden

Ours, and the only one here with nothing attached to it. It reads champ select from the League client, works out what the queue actually calls for, and imports the loadout in one click without touching rune pages you made yourself. Native Windows at 26 MB, no ads, no account, no subscription, and no build held back for people who pay. It's in open beta.

04 What to check before you pick

Feature lists all look the same at a glance. These are the questions that actually separate them once it's installed and you're in champ select with twenty seconds left.

Warden is the only one of the five that answers all six the way you'd want. No ad in the window. Nothing installed alongside it. Nothing held back for paying users. No account. 26 MB of native Windows. And yes, it reads the queue before it recommends anything.

The honest take

On the job all five advertise first, getting the right runes and items in before the loading screen, Warden is the one that does it without charging you, showing you an ad, or installing a platform to get there.

Everything else here wants something back for it. That's the reason we built Warden, and it's why we'd put it first.

FAQ Common questions

What is the best League of Legends companion app?

For the job all of them advertise first, getting the right runes and items in before the loading screen, we would say Warden, and we make it, so weigh that accordingly. It is the only one of the five with no ads, no account, no subscription and nothing installed alongside it, at 26 MB. Blitz is the best known and spans several games, though its Masters+ builds sit behind Premium at $4.99 a month. Porofessor and Mobalytics add lobby scouting and analytics, and both install the Overwolf platform. OP.GG Desktop is standalone like Warden but ships 84 MB of Electron with ads.

Are League companion apps free?

All five here are free to download. Blitz, Porofessor, Mobalytics and OP.GG carry ads in their free versions. Blitz Premium is $4.99 a month, or $3.33 a month billed annually, and removes ads and unlocks its Masters+ builds. Porofessor and Mobalytics sell tiers that remove ads too. Warden is free with no ads and no paid tier.

Which League companion apps do not require Overwolf?

Blitz, OP.GG Desktop and Warden all run standalone. The OP.GG store page states explicitly that it does not require the Overwolf client. Porofessor and Mobalytics are Overwolf apps, and both store pages state that downloading them installs the Overwolf client.

Can I get banned for using a League companion app?

These apps work through the local League client interfaces Riot exposes to third-party tools, doing things you could do by hand in the client, like creating a rune page or an item set. They do not automate gameplay or touch game files. We are not Riot and cannot speak for them, but this category of tool has operated in the open for years.

Do I need more than one companion app?

Usually not. Running two at once tends to be more annoying than useful. Warden creates its own clearly named rune pages, so it will not fight with anything else you already have installed.
