Fastest free Flare RPC, live no-key EVM endpoint latency
HTTP round-trip latency for the `eth_getBlockByNumber("latest", false)` method against every free, no-key public Flare EVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Ankr leads rpc latency at 50 ms (p50, 24h) on Fastest free Flare RPC, live no-key EVM endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/flare-rpc.

Flare is an EVM-compatible L1 blockchain (chain 14) specialising in cross-chain data acquisition, featuring native enshrined oracles (FTSOv2 for price feeds, FDC for cross-chain attestation), no staking-for-security requirement, FLR as its gas token, and ~1.8 s block cadence. The 2026-08-04 audit confirms 4 clean keyless providers: the Flare Foundation official endpoint (flare-api.flare.network/ext/bc/C/rpc), dRPC (flare.drpc.org), Thirdweb (14.rpc.thirdweb.com), and Ankr (rpc.ankr.com/flare). Excluded: Alchemy (no Flare route), QuickNode (key required).
Methodology
Per-chain member of the RPC latency cluster, extended to Flare. We measure the round-trip latency of a single, identical JSON-RPC call (`eth_getBlockByNumber("latest", false)`) against every no-key public Flare endpoint that sustains continuous probing, 4 providers measured, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Flare-scaled staleness gap (20 blocks at Flare's ~2 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Flare-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Flare RPC right now?
Ankr currently leads at 50 ms (`eth_getBlockByNumber("latest", false)` p50 over the last 24h), measured against 4 no-key providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples. Use the region tabs to see the leader from the origin closest to your deployment.
Which Flare RPCs work without an API key?
4 endpoints sustain continuous keyless probing: Flare Foundation (https://flare-api.flare.network/ext/bc/C/rpc), dRPC (https://flare.drpc.org), Thirdweb (https://14.rpc.thirdweb.com), and Ankr (https://rpc.ankr.com/flare). Every listed endpoint was live-verified with a `eth_getBlockByNumber` POST returning a parsable response before inclusion.
Does the fastest Flare RPC change by region?
Often. Public infra concentrates in specific regions; a gateway that wins from Amsterdam can lose from Singapore by multiples. The region tabs at the top of the page re-scope every number to a single origin; pick the one closest to where your requests originate.
How is Flare RPC latency measured here, technically?
One identical `eth_getBlockByNumber("latest", false)` POST every 60 seconds against each provider from each of 3 regions, using the same plain HTTP client the rest of the RPC cluster uses. 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.
