Published prices, not invoices. Each figure is human-verified against the provider's own pricing page or API and carries the date it was read; the harness re-hashes 20 of those pages on a loop to catch an upstream edit. A 30-day month and flat traffic are assumed, the most generous reading. NOWNodes prices in EUR. A provider absent from a cell is not missing data: it has no plan that can serve that workload, usually a cap or a throughput ceiling rather than the price.

Free allowance
BlockPIn/aChainstackn/a

Allowance, not latency and not reliability. A plan that buys the most requests is not thereby the fastest or the most correct; those are measured on the per-chain RPC pages. Published allowances, human-verified against each provider's own pricing page with the date it was read. A free plan is one that costs nothing and renews, so Quicknode's one-month trial is not here. Where a provider publishes a daily cap it is multiplied by 30.

How this pair was selected

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.

Live data refreshes via ISR within 60 seconds of a new run. Sources are the same Prometheus queries surfaced on the parent benchmark pages.
