5Stack vs GS2-Matchmaking

5Stack is a free, self-hosted Counter-Strike 2 competition platform for communities, Discord servers, leagues, tournament operators, server hosts, organizations, schools, and LANs. It combines server provisioning, matchmaking, tournaments, statistics, replays, broadcasts, and community moderation. Players can queue for 1v1, 2v2, or 5v5 matches, with party support and regional matching based on latency. Organizers can run Single Elimination, Double Elimination, Round Robin, and Swiss formats, including multi-stage brackets and seasonal leagues. Match analysis includes economy breakdowns, clutches, roles, heatmaps, and movement paths. Browser-based 2D and 3D replays, demo playback, and automatic highlights are available; some rendering requires a GPU node. Broadcast tools include Stream Deck control, scoreboard overlays, a public watch hub, and picture-in-picture. Integrations include Discord, Valve and FACEIT imports, Twitch, YouTube, and Kick. Hosting requires a Linux server and domain, and GPU features require an NVIDIA GPU on native Linux.

GS2-Matchmaking is a managed service for grouping game players by conditions and finding opponents. In standard matchmaking, a player creates a gathering and others may join when they meet its requirements; it is deleted after reaching its required player count. Conditions can include up to five player attributes, role capacities, ratings, allowlists, and blacklists. Ratings follow a Glicko-2-based process, starting at 1500 and changing with game results. Party tokens allow gatherings with existing party members; player tokens last 3 minutes and party tokens last 10 minutes. Season matchmaking keeps gatherings for a specified period and supports up to 1000 players, but only searches by GS2-Experience rank and does not allow players to leave during the season. The service supports latency or region matching and server allocation. SDKs cover Unity, Unreal Engine 5, Godot 4, Go, PHP, Java, C#, TypeScript, and Python. The Individual plan is free for eligible users, subject to request-rate thresholds and a GS2 logo requirement at launch.
