Nakama (Heroic Labs)
Open-source game server by Heroic Labs providing real-time multiplayer, social features, leaderboards, and matchmaking — deployable self-hosted or via Heroic Cloud managed service.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Self-hosted deployments place full security responsibility on the operator — TLS, firewall rules, and key rotation are not enforced by default. Server key is a single shared secret. Heroic Cloud provides managed TLS and network isolation.
⚡ Reliability
Best When
Building a real-time multiplayer game where you need full control over server logic and data, with the option to self-host on your own infrastructure.
Avoid When
Your team lacks backend engineering capacity to operate and scale a stateful game server, or you need a fully managed zero-ops solution.
Use Cases
- • Implement real-time authoritative game state sync between players using Nakama's relayed or authoritative match handler
- • Build social friend graphs with presence notifications so agents can trigger events when friends come online
- • Run custom server-side game logic via Lua or TypeScript runtime modules without managing a separate server
- • Automate leaderboard resets and reward distribution using scheduled server-side functions (cron-style runtime calls)
- • Manage in-game economy (wallets, item grants, store purchases) programmatically via the REST or gRPC API
Not For
- • Teams without DevOps capacity for self-hosted Kubernetes or Docker deployment — managed Heroic Cloud adds cost
- • Purely mobile attribution or analytics — Nakama is a game server, not an analytics platform
- • Games requiring a purely serverless architecture — Nakama requires a persistent stateful server process
Interface
Authentication
Server key (static) used for server-to-server calls. Players authenticate via device ID, email, social providers (Google, Apple, Facebook), or custom tokens and receive a session token. HTTP key (separate from server key) required for REST API access to admin console endpoints.
Pricing
Self-hosted costs are infrastructure only. Heroic Cloud pricing scales with concurrent users (CCU) rather than MAU.
Agent Metadata
Known Gotchas
- ⚠ gRPC and REST APIs are not 1:1 feature-equivalent — some admin features are REST-only via the console API
- ⚠ Runtime modules (Lua/TypeScript) are loaded at server startup; deploying new logic requires server restart unless using Heroic Cloud hot reload
- ⚠ Session tokens expire (default 60s for refresh token window) and must be refreshed; agents that don't handle token refresh will get 401s
- ⚠ Self-hosted deployments require CockroachDB or PostgreSQL — agents connecting directly to the database bypass all Nakama access controls
- ⚠ Match presence events are delivered over WebSocket only — REST polling cannot subscribe to real-time match state changes
