Alchemy and Chainstack are compared on 9 shared OpenChainBench benchmarks. Alchemy leads on Ethereum RPC endpoints. Chainstack leads on Solana RPC endpoints. See the live table on this page for every metric.
On the Ethereum RPC endpoints benchmark, Alchemy leads at 37 ms versus Chainstack at 68 ms. Live measurement is updated continuously by the OpenChainBench harness.
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
