The software between a game server and a league. One self-hosted install runs the whole stack: matchmaking, tournaments, stats, replays, and broadcast.
Overview
5Stack is a self-hosted competition platform for Counter-Strike 2. One install runs the entire lifecycle of competitive play: it provisions the servers, matchmakes the players, runs the map veto, controls the live match, holds the tournament structure, captures and parses the demos, computes the statistics, renders 2D and 3D replays, streams the broadcast, cuts the highlight reel, and moderates the community.
Is it for you?
Communities & Discord servers
Running pugs, scrims, and the occasional cup, and tired of stitching together a bot, a bracket site, and a spreadsheet.
League & tournament operators
Multi-stage brackets, seasonal divisions, negotiated scheduling, prize pools, and a bracket you can put on a stream.
Server hosts
Turn a rented box into a competitive platform. Multi-region orchestration, automatic CS2 updates, and white-label branding.
Orgs, schools & LANs
A branded platform with real analytics, offline-capable LAN servers, and venue-ready bracket displays.

5Stack is self-hosted and built to be adapted, not just configured.
Brand it
Your name, your logo, your login page, and full light/dark theming, so it reads as your organization's platform, not someone else's.
Extend the panel
Embed your own web apps as native 5Stack pages. Plugins inherit the panel session and design system, no fork, no rebuild.
Extend the game
Run your own CS2 server-side plugins alongside 5Stack's, on either CounterStrikeSharp or SwiftlyS2.
One command gets you a full install, Kubernetes, database, storage, and panel.
