Alchemy Compute Units vs BlazingNode request limits
Alchemy prices RPC usage with Compute Units. BlazingNode prices Polygon RPC with clear monthly request limits, included traces, and USDC plans. The right choice depends on whether your team wants usage optimization or cost predictability.

Short answer
Choose Alchemy if you want a broad Web3 developer platform, many APIs, dashboards, SDKs, and multi-chain support. Choose BlazingNode if you want Polygon-only RPC with direct monthly request limits, included trace calls, and less CU math.
Who this page is for
- Developers who like Alchemy but struggle forecasting costs
- Teams seeing CU usage grow on Polygon
- Users with heavy logs, traces, simulations, or method mix variance
What Compute Units mean
One request is not always one billing unit. Lightweight methods may cost fewer CUs, heavier methods more CUs, and throughput is expressed in CUPS as well as request rate.
Why CU pricing can surprise teams
Request count can stay stable while cost rises because method mix gets heavier. Logs, traces, simulations, webhooks, and richer data features can all change CU burn without changing the number of top-level requests very much.
| Topic | Alchemy | BlazingNode |
|---|---|---|
| Billing unit | Compute Units | Direct monthly requests |
| Free or trial | 30M CU free, 25 RPS | 7-day workload trial |
| Throughput model | CUPS / RPS model | Clear plan RPS limits |
| Trace and debug | PAYG or Enterprise, not Free | Included monthly traces on paid plans |
| Best for | Broad developer platform | Polygon-only operator workloads |
| Cost forecasting | Depends on method mix | Fixed plan envelope |
| Add-ons | Platform-specific usage expansion | 10M request packs, traces, burst passes |
Example: why 10M requests can mean different things
Ten million light calls at 10 CU each is 100M CUs. Ten million average calls at 27 CU each is 270M CUs. Heavier workloads can go far beyond that. This does not make CU pricing unfair. It means the buyer has to model method mix. BlazingNode counts monthly request volume directly, but it still has plan limits and is not trying to be every type of Web3 platform.
Where Alchemy is stronger
- Multi-chain platform breadth
- Developer tooling and broader APIs
- Established ecosystem and dashboards
- Advanced platform products beyond base RPC
Where BlazingNode is stronger
- Polygon-only focus
- Direct monthly request limits
- Included trace calls
- Extra 10M request packs for 35 USDC
- USDC billing
- Simpler price conversation for operators
- RPC Checker and 7-day workload trial
Who should switch?
| Need platform breadth | Stay with Alchemy. |
| Main pain is CU forecasting | Test BlazingNode. |
| Need Polygon trace cost clarity | Compare included trace allowances. |
| Need SDK and broader app APIs | Alchemy may still fit better. |
| Main pain is Polygon RPC instability or unclear monthly cost | BlazingNode workload trial is the rational next step. |
