Polygon has no chain-official endpoint in the free tier, so this is the purest gateway-versus-gateway comparison in the cluster: PublicNode, dRPC, 1RPC, Tenderly and Nodies, all answering the same `eth_blockNumber` probe every 15 seconds from three regions. With no house endpoint to anchor expectations, the regional flips between gateways decide the ranking, and they flip often.
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 Polygon endpoint that sustains continuous probing, 5 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 Polygon-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Polygon RPC right now?
dRPC currently leads at 22 ms (`eth_blockNumber` p50 over the last 24h), measured against 5 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 Polygon RPCs work without an API key?
The 5 providers on this page: PublicNode, dRPC, 1RPC, Tenderly, Nodies. 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 Polygon 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 Polygon 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 is there no official Polygon RPC in this benchmark?
Polygon's historically documented public endpoint (`polygon-rpc.com`) is operated by a third party and has moved in and out of key-gating and rate-limit regimes that break our 15-second probe cadence. The bench includes only endpoints that sustain continuous no-key probing; the multi-chain gateways above all pass that bar on Polygon.
