01 The short version
Porofessor is a scouting tool that also does builds. It's in the draft from the first second with ban suggestions and counterpick tips, it surfaces recent form for everyone in the lobby, and it imports runes straight into the client.
Plenty of people install it, use the rune import, and close it. If that's you, you're running the Overwolf platform and an ad-supported app for about six seconds of work a game. That's the case Warden was written for. If you'd rather see the whole field at once first, we put the League of Legends companion apps side by side.

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 Porofessor
A lot, including things you didn't go looking for. Porofessor scouts the lobby, flags rough matchups and suggests bans while the draft is still moving.
To get any of it you install the Overwolf platform alongside the app, and the free tier carries ads with a Premium tier to switch them off. Its standalone build is listed at 100.8 MB against Warden's 26. If keeping a second platform off your PC is the point, here's which companions run without Overwolf.
04 Where the builds come from
Every night we pull the current patch from Data Dragon and CommunityDragon and rebuild the recommendations from match data, rather than reprinting someone else's tier list. Win rates get ranked on a Wilson lower bound, which is a long way of saying a 58% win rate over 40 games doesn't get to outrank a 53% over twelve thousand. The small-sample noise stops floating to the top, which matters most on the champions nobody plays.
Mode changes the model, not just the item list. Rift builds are role-aware, so mid Ahri and support Ahri don't get handed the same page. ARAM weights sustain and poke, because you can't go back. Arena ranks augments alongside the build, because the augment is usually what decides the round.
Warden itself is a native Windows app, which is why it's 26 MB and opens instantly instead of starting a browser engine to draw a list of item icons.
The honest take
Most people open Porofessor, use the rune import, and close it again. That's a platform install, an ad slot and 100 MB for about six seconds of work a game.
Warden does those six seconds in 26 MB, with no ads, no account and nothing installed beside it. If the loadout is what you were there for, Warden is the better tool for it, and it costs nothing to find out.
