The no-key field thins out on Linea: 4 providers qualify (PublicNode, dRPC, 1RPC, Tenderly), all multi-chain gateways. Thinner competition makes the reliability columns matter more than raw speed, a fast endpoint with a high stale or timeout rate is a worse default than a slightly slower consistent one. Probes run every 15 seconds from us-east, eu-west and Singapore with full response classification.
Methodology
Per-chain member of the RPC latency cluster. We measure the round-trip latency of a single, identical RPC call (`eth_blockNumber`) against every no-key public Linea endpoint that sustains continuous probing, 4 providers, every 15 seconds, from us-east, eu-west and Singapore. The harness also classifies every response (ok / http_err / jsonrpc_err / stale / timeout) and audits archive depth every 5 minutes, so the leaderboard rewards sustained, honest availability rather than a fast error message. The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Linea-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Linea RPC right now?
dRPC currently leads at 23 ms (`eth_blockNumber` p50 over the last 24h), measured against 4 no-key providers probed every 15 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples, so the answer on this page is the answer right now, not a quarterly snapshot. Use the region tabs to see the leader from the origin closest to your deployment.
Which Linea RPCs work without an API key?
The 4 providers on this page: PublicNode, dRPC, 1RPC, Tenderly. Every (provider, chain) pair was live-verified no-key before inclusion, and anything that key-gates, region-blocks or rate-limits below our 15-second cadence is excluded rather than listed with an asterisk.
Does the fastest Linea RPC change by region?
Frequently. The headline number averages three probe origins (us-east, eu-west, Singapore), but per-region leaders regularly diverge, a gateway that wins from Virginia can lose from Singapore by multiples. The region tabs at the top of the page re-scope every number on the page to a single origin; pick the one closest to where your requests actually originate.
How is Linea RPC latency measured here?
One identical JSON-RPC POST (`eth_blockNumber`) every 15 seconds against each provider from each of 3 regions, with the same plain HTTP client. Wall-clock round-trip is recorded at millisecond precision; p50/p90/p99 are computed via Prometheus `quantile_over_time` over 24 hours. Responses are classified (`ok` / `http_err` / `jsonrpc_err` / `stale` / `timeout`) so an endpoint stuck on an old head or returning errors behind HTTP 200 is never ranked as fastest. The harness is open source and every number on this page is a public Prometheus query you can run yourself.
Why do so few free RPCs support Linea?
Free-tier coverage follows demand: gateways add no-key chains when traffic justifies the infrastructure. Linea's cohort (4 providers) is typical of newer L2s, compare with 9 on Ethereum and 8 on Arbitrum. The flip side is that the providers that do qualify are the disciplined multi-chain operators, so the reliability floor is high even where the field is thin.
