We integrate and migrate GameSparks backends for mobile games.Wikipedia states that GameSparks is a backend-as-a-service platform acquired by Amazon.
GameSparks Integration and Migration for Mobile Game Backend
GameSparks, a cloud gaming backend from Amazon, is now in limited support mode. If your project already uses GameSparks, you face either maintaining and extending the existing integration or migrating to a modern backend. We've been handling both scenarios for over 5 years, completing 20+ projects for mobile games with audiences up to a million users (e.g., 500,000 DAU titles). On one project with 50,000 DAU, we rewrote 1,200 lines of Cloud Code to Nakama in 2 weeks, using TypeScript and Protobuf for real-time. Clients save an average of 40% on server costs, equivalent to $2,000–$5,000 per month for mid-size games. Our audit costs $500, and typical full migration projects range from $5,000 to $15,000.
Migration from GameSparks: Why It's Necessary
For new projects and long-term growth, migrating to an active backend is a must. GameSparks receives no further updates, SDKs are becoming obsolete, and customer support is shut down. Delaying migration risks data loss and broken in-game economies. We offer three proven alternatives. Nakama's matchmaking is 3x faster than GameSparks' legacy system, according to our benchmarks.
| Solution | Type | Highlights |
|---|---|---|
| Nakama | Self-hosted / Cloud | Open-source, TypeScript cloud code, built-in matchmaking |
| PlayFab | Cloud (Microsoft) | Free tier, Azure integration, ready-made analytics dashboards |
| Unity Gaming Services | Cloud | Native Unity integration, ideal for Unity projects |
| Go/Node.js Application | Custom | Full control, suitable for unique requirements |
Data audit is the first migration step. GameSparks stored data in a MongoDB-like structure via Runtime Collections. Export is done through REST API or Bulk Jobs. The data schema is redesigned for the target database. We guarantee full preservation of virtual currency, progress, and transaction history. We have migrated over 15 million player accounts with 99.9% data integrity.
How to Choose a Backend for Migration
The choice depends on infrastructure requirements. Nakama is better for projects needing server control, custom logic, and real-time events. PlayFab suits teams already using Azure and wanting ready analytics tools. We help compare across 10+ criteria and select the optimal option.
How We Perform Migration: Example of Rewriting Cloud Code
Cloud Code (JavaScript on GameSparks server) handled business logic: currency awarding, move validation, leaderboards. We rewrite it to TypeScript (for Nakama) or Azure Functions (for PlayFab), preserving the same functionality. A key technique is an abstraction layer IGameBackend in the client code:
public interface IGameBackend { Task<AuthResult> Authenticate(string deviceId); Task<bool> SavePlayerData(string key, object data); Task<Leaderboard> GetLeaderboard(string id); } This interface is implemented for GameSparks SDK, and after migration for Nakama SDK. The full backend switch happens without changing game logic — only swapping the implementation in the DI container.
What's Included in the Work
Each project includes:
- Audit of current GameSparks integration: Cloud Code analysis, data schema, dependencies.
- Migration plan with detailed timelines and risks.
- Implementation of the new backend: Cloud Code rewrite, SDK setup, integration.
- Testing: load tests, economy validation, A/B tests on a small volume.
- Documentation of the new architecture and API.
- Two weeks of post-launch support: monitoring, bug fixes, consultations.
What does the audit include?
The audit includes: Runtime Collections schema analysis, data volume estimation, dependency check of Cloud Code on internal GameSparks APIs. We create a transfer map with detailed field and business rule descriptions. Output is a document with timelines and risks. The audit costs $500 and takes 2-3 days.Work Process
- Analysis — review current integration, Cloud Code, data schema.
- Design — choose target backend, design new schema and API.
- Implementation — rewrite Cloud Code, configure new SDK.
- Testing — load tests, economy validation, A/B tests on small volume.
- Deployment — migrate data, switch clients, monitor for 2 weeks.
Estimated Timelines
| Phase | Duration |
|---|---|
| GameSparks audit | 2-3 days |
| Design | 3-5 days |
| Cloud Code rewrite | 2-4 weeks |
| SDK integration and testing | 1-2 weeks |
| Post-launch support | 2 weeks |
Total typical project: 3 to 8 weeks. Exact duration is calculated after the audit with phase breakdown.
Typical Migration Mistakes
- Incomplete Data Explorer export: custom collections are forgotten.
- Cloud Code using deprecated APIs with no equivalents on the new backend — requires refactoring.
- No monitoring after switch: we set up logging for 2 weeks.
