Alchemy CU calculator
Use to show why “requests/month” is not enough: methods have different CU weights.
Interactive calculators · sales discovery
Translate CU, credits, RU and daily quotas into a production RPC recommendation.
Use this page in discovery calls to move buyers away from “which provider is cheapest?” and toward method mix, peak RPS, archive/debug usage, support, and dedicated-capacity triggers.
Workload inputs
Defaults use Alchemy’s published rough average of 27 CU/request as a starting point from the source-gated research. Replace with real customer logs when available.
QuickNode credits calculator
Use to compare monthly credits and visible RPS ceilings separately.
Chainstack RU comparison
Use to discuss Request Units and method/feature uplift explicitly.
Infura daily-credit estimator
Use to separate daily quota from credit/second throughput risk.

Sales rules of thumb
| Signal | Interpretation | Recommended motion |
|---|---|---|
| Peak ≥ 800 RPS | Shared plans may hit operational ceilings even if monthly cost looks fine. | Pitch dedicated/limitless proof pilot. |
| Archive/log/debug ≥ 15% | Weighted units can distort cost and job completion. | Run method-level workload review. |
| Backfills or launch windows | Average daily volume hides burst risk. | Benchmark p95/p99 and error rate by region. |
| Enterprise procurement | SLA/security/support docs matter as much as price. | Attach reliability pack + RCA template. |
