| Integrations | The maker lists Unity, Roblox, Godot, and custom game servers as supported integrations, and publishes JavaScript, Godot, Unity, and Roblox client SDKs. | The maker lists examples or guides for Kaboom.js, Phaser, PixiJS, Godot, Unity, and Unreal, alongside raw REST access. |
| Intended users | Crux says it is best suited to dedicated-server and multiplayer survival or co-op games, including indie and mid-size studios, and less suited to offline single-player games. | The maker describes the product for indie game developers, multiplayer game creators, hackathon builders, and game studios. |
| Security | Crux describes PostgreSQL row-level security, environment isolation, and separate API key, server token, and player JWT access modes. | The service supports HMAC-SHA256 score signing, per-key rate limits, and score bounds; its documentation says API keys and score secrets should stay server-side. |
| Support | Dev includes community support, Launch includes email support, and Scale includes priority email support. | Priority support is listed as a Pro plan feature. |

In their own words
Crux
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.
