Sui RPC endpoints: free public URLs by latency
HTTP round-trip latency for sui_getLatestCheckpointSequenceNumber against every free, no-key public Sui RPC endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , OnFinality has the lowest median latency of the 4 free public Sui RPC endpoints measured, 65 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/sui-rpc. 4 public endpoints, no key: sui.api.onfinality.io, sui-rpc.publicnode.com, mainnet.suiet.app, sui-mainnet-endpoint.blockvision.org. Full URLs with their 24h median are listed below.

Sui is a Move-based L1 blockchain using the Mysticeti DAG-BFT consensus protocol, producing checkpoints every roughly 3 seconds with deterministic sub-second finality. Free public RPC endpoints are available without an API key from Mysten Labs, PublicNode, BlockVision, Suiet and OnFinality. Every provider was live-verified with consecutive keyless sui_getLatestCheckpointSequenceNumber probes at launch.
Methodology
Sui: 4 free public RPC endpoints answering `sui_getLatestCheckpointSequenceNumber` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. OnFinality leads at 65 ms. We measure the round-trip latency of a single, identical JSON-RPC call (sui_getLatestCheckpointSequenceNumber) against every no-key public Sui endpoint that sustains continuous probing: 4 providers live today, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Sui-scaled staleness gap (100 checkpoints, around 5 min). The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Sui-scoped answer with per-region breakdowns as a first-class dimension.
