BACKND vs Crux

BACKND is a backend API and SDK for game developers adding multiplayer and backend services to games. BACKND Base offers authentication, cloud data storage, rankings, notices, social functions, events, coupons, push notifications, receipt verification, and an admin console. Match handles 1:1, individual, and team matchmaking, with result processing and reconnection. Worlds provides persistent servers and real-time synchronization for MMO and other multiplayer games. Other services include real-time chat with moderation, profanity filtering, reports, sanctions, and translation; a database for user and shared game data; and server-side functions written in C# using Unity-style syntax. Documentation lists Unity and Unreal SDKs, a Platform API, and a.NET SDK. Worlds officially supports Unity, while other engines can call server APIs directly. The company says users can test all features for free, but gives no trial duration. Database FREE includes 300 MB read bandwidth, 100 MB write bandwidth, and 200 MB storage; exceeding the allowance can restrict game use. Listed paid plans include chat options from $9.00 per month and a database plan at $29.00 per month.

Crux provides multiplayer game backend services for player authentication, persistent data, leaderboards, server registration, live configuration, game economies, and matchmaking. Authentication supports email and password, guest sessions, Google, GitHub, and Discord OAuth, as well as Roblox verification. Developers can store player- or project-scoped JSON documents and configure ranked or seasonal leaderboards with recurring resets. Economy tools handle currencies, virtual items, and inventories through atomic, server-authoritative updates. Matchmaking queues players by game mode and region, then assigns them to live servers from the dedicated server registry. The maker lists Unity, Roblox, Godot, and custom game servers as integrations, with client SDKs for JavaScript, Godot, Unity, and Roblox. The hosted API is documented with OpenAPI, and client SDKs are MIT-licensed; the managed backend is proprietary. Crux has a free Dev plan and paid plans from $10.00 per month. Runtime is a capacity-gated closed alpha for Godot 4 Linux dedicated-server exports, with Dev evaluation limited to admitted projects. Crux says it best suits dedicated-server multiplayer survival or co-op games.
