I am working on a new open source game server with authentication, users, lobbies, server scripting and admin portal, built with Elixir. Links:

• Github
• Website
• Guides

Competition

This is how it compares with what exists today:

Solution	Language	Auth	Persistence	Friends	Scaling	Cost after ~5k CCU
Gamend	Elixir	Yes	SQLite / PostgreSQL	Yes	Horizontal (BEAM clustering)	$0
Nakama	Go	Yes	PostgreSQL	Yes	Manual sharding or paid cloud	$1k+/mo (cloud)
Colyseus	TypeScript	Beta	No	No	Node clustering	$0

• Note 1: Since Gamend works with SQLite also, hosting a single instance costs just 5$.
• Note 2: Nakama costs after scaling because it either requires manual configuration (hard to setup, not trivial) or enterprise version. Colyseus and Gamend both scale normally, without any enterprise edition. reddit/nakama_not_an_opensource_distributed_server

Features

a. Authentication:

• Email + password
• Magic links
• OAuth 2.0 / OIDC providers (Steam, Google, Discord, Facebook, Apple)
• JWT and session support
• Password reset, email verification

b. Realtime lobby system via Phoenix Channels and Presence:

• Create/join public or private lobbies
• Live player list with metadata, as well as live lobby data.
• In-game ready checks and scripting

c. User profiles and persistent data:

• PostgreSQL or SQLite (for lightweight setups)

d. Responsive web UI included

• Login, registration, lobby browser, profile pages

e. Guides

• Guides on how to configure everything on server side (eg. oauth, etc.) and on the client side.

f. Admin dashboard

• User management, lobby overview, basic analytics
• Integrated Sentry error tracking

Roadmap

I intend to add to it also:

• Leaderboards
• Groups
• Tournaments
• etc.
