5Stack vs Asobi

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.

Asobi is an open-source multiplayer game backend built on Erlang/OTP for solo developers and small teams making indie 2D games. It provides authentication, matchmaking, real-time sync, leaderboards, a virtual economy, social features, cloud saves, and an admin dashboard. Developers can build ephemeral matches or persistent worlds with lazily loaded zones. Lua match logic can be changed while a match runs, with updates taking effect on the next tick. Official client SDKs are listed for Unreal, Unity, Godot, Defold, TypeScript/JavaScript, Dart/Flutter, Lua, and LÖVE. Monitoring includes OpenTelemetry integration, structured logging, and telemetry events for matches, queues, and connections. The Apache 2.0 core can run locally with Docker Compose or be self-hosted as a Docker container. Asobi Cloud is hosted on Hetzner in Germany and uses EU-only infrastructure subprocessors, but is invite-only while studios are onboarded. The project is single-node by design and pre-1.0, so minor breaking API changes may occur before 1.0.
