Fastest free Songbird RPC, live no-key endpoint latency
HTTP round-trip latency for eth_getBlockByNumber against every free, no-key public Songbird EVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Flare Foundation posts the lowest rpc latency at 316 ms (p50, 24h) on Fastest free Songbird RPC, live no-key endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/songbird-rpc.

Songbird (chain 19, SGB) is Flare Network's canary network, a production EVM-compatible chain used to test and validate Flare's FTSO oracle system before mainnet deployment. One keyless endpoint is probed continuously: the official Songbird gateway (songbird-api.flare.network/ext/C/rpc). The FTSO AU community node (songbird.rpc.ftso.au) was removed after DNS went dead.
Methodology
Per-chain member of the RPC latency cluster, extended to Songbird. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against the no-key public Songbird endpoint that sustains continuous probing (1 provider: Flare Foundation official), every 60 seconds, from us-east, eu-west and Singapore. The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Songbird-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Songbird RPC right now?
Flare Foundation currently leads at 316 ms (`eth_getBlockByNumber` p50 over the last 24h), measured against 1 no-key provider probed every 60 seconds from us-east, eu-west and Singapore.
Which Songbird RPCs work without an API key?
1 endpoint sustains continuous keyless probing: Flare Foundation official (songbird-api.flare.network/ext/C/rpc). The FTSO AU community node was removed after its DNS went dead.
Does the fastest Songbird RPC change by region?
Often. The region tabs at the top of the page re-scope every number to a single origin.
How is Songbird RPC latency measured here?
One identical JSON-RPC POST (`eth_getBlockByNumber`) every 60 seconds against each provider from each of 3 regions.
