Browser extension for FACEIT CS2

Know who you're playing before the knife round.

EloStack adds the stats FACEIT doesn't show you: ratings, roles, map records and a match forecast for all ten players, right in the match room. It also adds levels 11–20 for everyone over 2,000 ELO.

Everything in one extension

No more five tabs open in the match room. EloStack runs quietly on faceit.com and puts the numbers where you need them.

Match room stats

Rating, K/D, average K–D, ADR, win rate, matches in the last 24 hours and recent results for every player, plus team averages.

Forecast and ELO at stake

See your chance of winning and how much ELO you stand to gain or lose before the match starts.

Map stats and veto help

Both teams' records on every map, with pick and ban suggestions so you veto with data, not vibes.

Levels 11–20

Every 250 ELO above 2,000 earns a new level, shown across FACEIT, with a tracker and a celebration when you level up.

Form score

A 0–100 score from the last 20 matches, from Cold to On fire, so you can tell at a glance who's playing well right now.

Roles and history

AWP, ENTRY, CLUTCH and SUPPORT tags, "played before" markers, and a scouting card on every profile: you vs them.

Auto-accept

Grab a drink while you queue. EloStack accepts the match for you after a delay you choose. Off until you turn it on.

Auto-call

Set a position for each map and EloStack posts it in team chat as soon as the map is locked.

Quick links and popup

One click to Steam, Leetify or csstats for any player, and your ELO, peak and progress in the toolbar popup.

Free. All of it.

Questions

Is EloStack safe to use? Will it get me banned?

EloStack only runs on the faceit.com website in your browser. It never touches CS2, the FACEIT anti-cheat or your game files, and it reads public stats from the official FACEIT Data API.

Do I need a FACEIT API key?

No. By default EloStack fetches stats through its own server, so it works straight away. If you'd rather, you can use your own FACEIT API key in the settings.

Which browsers does it work in?

Any Chromium browser: Chrome, Opera and Opera GX, Edge, Brave, Vivaldi. Firefox isn't supported yet.

Is it really free?

Yes. Everything listed above is free. Optional premium extras will come in a later update, and the free features will stay free.

What do you do with my data?

Very little. Your settings, notes and ELO history stay in your browser. The privacy policy lists exactly what reaches our server and why.

Free beta coming soon

EloStack is heading to the Chrome Web Store and Opera add-ons. Follow along and grab it the day it lands.
