Alchemy Compute Units True-Cost Calculator
Translate Alchemy's 75x log weights and 170x trace multipliers into predictable monthly dollars.
Alchemy calculates usage using Compute Units: `eth_getLogs` costs 75 CUs, `eth_call` costs 26 CUs, and debug traces cost 170 CUs. An indexing app running 10M requests can consume over 500M CUs, leading to hundreds in surprise overage charges.
Use this interactive modeler to compare your actual workload under Alchemy's CU formula against BlazingNode's transparent flat-rate plans.

Head-to-Head Calculator
Side-by-side audit calibrated against official first-party documentation. While Alchemy measures your traffic through complex billing units (170 CU per call (official doc rate) on traces and 75 CU per call (75x penalty) on logs), BlazingNode guarantees transparent 1:1 request counting with zero Compute Unit multipliers.

Core distinction: Compute Units Weighted Matrix vs dedicated 1:1 Polygon RPC
Alchemy meters usage under its Compute Units Weighted Matrix model on the PAYG Tier at $0.52 per million CU tier (up to 40 RPS, 7.8% multi-region tip drift). In contrast, BlazingNode provides dedicated Polygon PoS capacity with strict 1:1 request counting, included debug_traceTransaction quotas, included Deep Calls (>128 blocks), 300 RPS burst headroom on Builder, Operator, and Pro, and 500 RPS on Business, starting at 49 USDC/mo.
Who this comparison is for
- Teams running Polygon PoS workloads on Alchemy who want predictable 1:1 monthly request envelopes
- Bot operators, arbitrageurs, and indexers experiencing p95 tail latency or stale block reads on shared cloud proxies
- Developers with heavy eth_getLogs, archive Deep Calls, or debug_traceTransaction workloads tired of unit multipliers
Key Architectural Differences
Direct Request Envelopes
Every request counts as 1. No hidden multiplication factors.
Included Trace Allowances
25k to 200k trace calls bundled directly into paid plans.
No Overage Shock

| Specification | Alchemy (PAYG Tier at $0.52 per million CU) | BlazingNode (Builder — $49/mo) |
|---|---|---|
| Billing & Metering Model | Compute Units Weighted Matrix | Direct 1:1 Monthly Requests (20M–160M+ included) |
| Event Logs (eth_getLogs < 128 blocks) | Metered via unit multipliers or shared RPS pool | 1:1 request metering with zero Compute Unit multipliers |
| Deep Archive Calls (> 128 blocks) | Multiplied compute/archive units or higher tier required | 2,500–35,000 included + Pay-As-You-Go Deep Calls Packs ($6–$89) |
| Trace & Debug (debug_traceTransaction) | High unit multiplier or restricted on entry plans | Included on all paid plans (25K, 50K, 100K, 200K/mo) |
| Throughput & Burst Ceiling | Up to 40 RPS | 300 RPS Peak Burst on Builder, Operator, Pro; 500 RPS Peak Burst on Business |
| Northeast Latency (Montreal / Ashburn p50) | 52ms / 42ms | 6.2ms (ca-central-1) / 16.5ms (us-east-1) |
| Stale Block Read / Tip Drift Rate | 7.8% multi-node sync variance | 0.00% measured block drift in sample benchmark windows |
Where Alchemy fits well
- Multi-chain hobbyist or generalist projects needing dozens of non-Polygon networks under one login
- Low-volume workloads that stay comfortably inside free or entry credit allowances
- Teams already locked into vendor-specific SDKs or proprietary webhook pipelines
Where BlazingNode is stronger
- Polygon PoS specialization on dedicated Bor nodes
- True 1:1 request counting (zero Compute Unit or Watch/Request Unit inflation)
- Included monthly trace quotas (25K to 200K) and Deep Calls allowances
- Pay-As-You-Go Volume, Trace, Deep Calls, and 72h Spike Passes that never auto-renew
- Instant USDC on-chain settlement on Polygon Mainnet with verifiable PDF receipts
- 72-hour mainnet trial (500K requests, 300 RPS burst)
Workload architecture breakdown
| High-throughput Polygon execution & bots | BlazingNode (Sub-17ms US-East / 6.2ms Montreal p50, tip-of-chain freshness) |
| Predictable Polygon monthly cost budgeting | BlazingNode (Zero CU/credit multiplier math; direct 1:1 monthly request caps) |
| Heavy eth_getLogs & Historical Deep Calls | BlazingNode (1:1 active logs <128 blocks + non-expiring Deep Calls Packs from $6) |
| Trace and debug call volume | BlazingNode (Up to 200K traces included on paid plans without 40x–1000x unit penalties) |
| Multi-chain application with high Polygon volume | Isolate Polygon PoS on BlazingNode; keep secondary chains on Alchemy |
