Nakama vs Firebase

This is intended to be a brief, objective, technical comparison of Nakama and Firebase.

If you feel this comparison is unfaithful for whatever reason, please send an email to

At A Very High Level

  • Heroic Labs' Nakama is an open-source server which can be hosted on any cloud as well as locally. Firebase is a proprietary SaaS service hosted in the cloud and cannot be self-hosted.
  • Nakama server and the client libraries are open source on GitHub. Nakama can be run on Windows, macOS, and Linux for development and production.
  • Nakama comes packaged with a database to provide a fully capable collection of services. No separate solutions are required for user accounts, social login, data storage, etc.
  • Firebase comes with a realtime data storage system which syncs data between server and client. It can store large blobs that uses cold-line storage as the backing mechanism.
  • Nakama handles persistent users and shared state as well as persistent chat history. Firebase does not have any higher order functionality (like built-in chat and presence system).
  • All of Nakama’s features: Realtime multiplayer, chat, matchmaker, server authoritative logic, etc. are available with the same server and license. Licenses for Nakama Enterprise (for multi-server clusters) includes all features and no artificial CCU limitations.
  • Firebase provides Performance Monitoring, Crash Reporting, Analytics for free. All other development tools (such as Realtime Database) are paid products.

Features/Capability Comparison

The table below gives a high level comparison of Nakama's Managed Cloud and Firebase platform. To keep the page relevant in the face of rapid development on both sides, low level details are found in links to the online documentation for Heroic Labs and Firebase.

Feature/Capability Managed Cloud (Nakama) Firebase
User Identification Nakama offers multiple methods to authenticate: including email/password, third-party social providers like Steam and Game Center. You can also use your existing user accounts service with the server. Firebase offers multiple methods to authenticate including third-party social providers. Optional UI element available.
Data Storage Data is stored in in JSON format in a postgres-compatible database. Each record has specific read-write permissions and can be updated using JSON-patch operations. All operations are batched and they include transactional update guarantees. Firebase stores JSON data and synchronizes changes with devices and persists data to disk.
Asset Storage Nakama doesn't store asset files directly. Instead you can store a version-specific manifest which lists all files and the link to download the files from cold-line storage like S3. Firebase stores and serves user-generated content such as photos or videos.
In-app Chat & Chat History 1 on 1, group, and room-based chat. Available as part of Nakama server and can be self-hosted. Persistent chat history, can be kept as long or short as required by the studio. Not available.
In-app and Push notifications Nakama pushes system notifications to the devices that are online automatically. You can send custom notifications and persist them for later delivery. Push Notification is available as a code module. Yes. You can segment users and send mass notifications, but notifications are not persisted for later delivery.
Custom Script Runtime Nakama has an embedded script runtime which utilises the Lua language to extend or override server behaviour. You can use the Runtime as before/after action hooks, RPC calls, or server-to-server HTTP calls. Cloud Functions are single-purpose JavaScript functions that are executed in a managed Node.js environment.
Remote Configuration Yes. You can read more about it here. Firebase Remote Config includes a client library that handles important tasks like fetching parameter values and caching them.
Matchmaking & Multiplayer Engine Turn-based and realtime. The engine itself is realtime and works as a message broker. Turn-based games have their state managed in-memory on the server. Firebase does not have any multiplayer capabilities.
Transport Protocol WebSocket, secure rUDP (reliable-ordered and unreliable-unordered) based on the specs. WebSocket
Sync Behaviour Data is pushed to clients over a background socket. Data is persisted by the server, and state is tracked. If client lose network connectivity, they can then rejoin at a later point. Data stored in the Firebase realtime database is pushed to the clients. Authentication, asset storage, etc use request-response model.
Hosted Any cloud of your choice, local or bare metal. We also offer a Managed Cloud for developers who do not wish to operationalise their own infrastructure. Hosted on Google servers, and cannot be self-hosted.
Open-source Fully open-source server. Closed source.
