OnFinality vs Alchemy for Blockchain RPC APIs

Compare OnFinality and Alchemy for multichain RPC endpoints, uptime, pricing, archive access, Trace API, request analytics, and production Web3 workloads.

Why teams compare OnFinality with Alchemy

Alchemy is commonly considered for Ethereum and EVM developer tooling. OnFinality is a strong fit when teams need broader production infrastructure across RPC APIs, supported mainnets and testnets, archive access, request visibility, and dedicated node options for workloads that outgrow shared APIs.

Multichain RPC coverage

Use one RPC infrastructure provider across production networks, testnets, and emerging ecosystems instead of stitching together separate providers.

Request analytics

Track usage patterns, response units, and endpoint behaviour so your team can understand demand before it becomes an infrastructure problem.

Archive and Trace API

Support heavier data workloads with archive access and Trace API availability on supported networks and paid plans.

Dedicated node path

Start with shared RPC APIs, then move high-throughput or custom workloads to dedicated blockchain nodes when your app needs isolated resources.

Decision guide

How to evaluate OnFinality and Alchemy for EVM applications

For EVM teams, the comparison should start with the application workflow: contract reads, transaction delivery, log indexing, real-time updates, and the networks that must be operated together.

Continue with Alchemy when

  • Your roadmap is centred on an existing EVM tooling workflow and that workflow covers the networks and developer services you need.
  • Your team has already validated its required RPC methods, quotas, and operational support model with Alchemy.

Consider OnFinality when

  • You need an EVM endpoint alongside Solana, Polkadot, or other supported networks from one provider.
  • You are planning a path from shared RPC access into archive, trace, or dedicated infrastructure for a specific workload.

Run a like-for-like test

Use a representative EVM test set: eth_call for user-facing reads, eth_getLogs for indexed ranges, transaction receipt polling, and any archive or trace calls your backend depends on. Repeat it on the target regions before moving production traffic.
