Sei Labs leads on the only live benchmark. Sei Labs wins on Fastest free Sei RPC, live no-key EVM endpoint latency (100 ms vs 668 ms).
Sei Labs' official public EVM RPC (evm-rpc.sei-apis.com) for the parallel-execution EVM layer on Sei's Cosmos SDK L1 (chain 1329). Standard EVM JSON-RPC, keyless, rate-limited per IP.
ThirdWeb operates a keyless public RPC gateway at `<chainid>.rpc.thirdweb.com` covering 2000+ EVM chains via chain-id routing. Free tier is rate-limited per IP with no signup; paid tiers unlock higher throughput and dedicated endpoints. Used keyless across 13 chains on the RPC latency cluster (arbitrum, ethereum, polygon, optimism, base, bnb, avalanche, linea, worldchain, kaia, ink, opbnb + more).

Sei Labs and thirdweb are compared on 1 shared OpenChainBench benchmarks. Sei Labs leads on Fastest free Sei RPC, live no-key EVM endpoint latency. See the live table on this page for every metric.
On the Fastest free Sei RPC, live no-key EVM endpoint latency benchmark, Sei Labs leads at 100 ms versus thirdweb at 668 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.
