Linea RPC endpoints: free public URLs by latency
HTTP round-trip latency for eth_getBlockByNumber against every free, no-key public Linea RPC endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , PublicNode has the lowest median latency of the 3 free public Linea RPC endpoints measured, 70 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/linea-rpc. Chain ID 59144. 3 public endpoints, no key: linea-rpc.publicnode.com, gateway.tenderly.co, linea.drpc.org. Full URLs with their 24h median are listed below.

The no-key field thins out on Linea: 3 providers qualify, 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 60 seconds from us-east, eu-west and Singapore with full response classification.
Methodology
Linea: 3 free public RPC endpoints answering `eth_getBlockByNumber` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. PublicNode leads at 70 ms. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against every no-key public Linea endpoint that sustains continuous probing, 3 providers, every 60 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
Which Linea RPCs work without an API key?
The 3 providers on this page are listed with their URLs in the endpoints table above. Every (provider, chain) pair was live-verified no-key before inclusion, and anything that key-gates, region-blocks or rate-limits below our 60-second cadence is excluded rather than listed with an asterisk.
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 (3 providers) is typical of newer L2s; the Ethereum and Arbitrum pages list their own live counts. The flip side is that the providers that do qualify are the disciplined multi-chain operators, so the measured success rates (listed in the endpoints table) stay high even where the field is thin.
