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.
LEADR
LEADR provides leaderboard backend services and social engagement features for games. Developers can configure score units, sorting, per-player score handling, tags, icons, and shareable board codes. SDKs are documented for Godot, Unity, and Unreal, with support stated for additional game engines. Hosted boards get shareable web pages for embedding, and can run recurring seasons or timed events, reset automatically, and archive completed results. Described anti-cheat measures include client authentication and anomaly detection for suspicious submissions. LEADR offers cloud hosting and an Apache 2.0-licensed core that can be self-hosted using Docker Compose. The company says cloud data is stored in the EU, on servers in Germany, with automatic backups. Its privacy policy describes player data as pseudonymous and scoped to a game, without cross-game tracking. The Free plan is free and allows 10,000 score submissions per month; Indie is $7.99 a month and Studio is $129.99 a month.
