Build vs. Buy: Custom Feeds vs. Generic Solutions
Choosing between building a custom GameFi/NFT activity feed in-house or using a specialized provider like Chainscore impacts your time-to-market, security, and total cost of ownership. This comparison highlights the key trade-offs.
| Factor | Build In-House | Generic API Provider | Chainscore Custom Feeds |
|---|---|---|---|
Time to Market | 4-8 months | 2-4 weeks | 4-8 weeks |
Data Granularity & Customization | Full control | Limited, generic events | Tailored to your game economy |
Real-time Latency | Your responsibility | 500ms - 2s | < 500ms SLA |
Security & Audit Burden | High (your team) | Provider risk | Audited, battle-tested infrastructure |
Multi-chain Support (e.g., Ethereum, Polygon, Immutable) | Complex integration per chain | Often limited | Native, unified API |
Ongoing Maintenance & Updates | Dedicated 1-2 engineers | Provider roadmap | Fully managed service with SLA |
Total Cost (First Year) | $150K - $400K+ | $10K - $50K | $50K - $150K |
Scalability for Player Growth | Your team scales infra | Tiered limits, overage fees | Automatically scales, predictable pricing |
