Stellar Soroban RPC endpoints: free public URLs by latency
HTTP round-trip latency for getLatestLedger against every free, no-key public Stellar Soroban RPC endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Gateway.fm has the lowest median latency of the 5 free public Stellar Soroban RPC endpoints measured, 142 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/stellar-rpc. 5 public endpoints, no key: soroban-rpc.mainnet.stellar.gateway.fm, stellar.api.onfinality.io, rpc.lightsail.network, mainnet.sorobanrpc.com, rpc.ankr.com. Full URLs with their 24h median are listed below.

Stellar uses the Stellar Consensus Protocol (SCP) with roughly 5-second ledger closes and deterministic finality on every close. Soroban is Stellar's smart contract platform with a dedicated JSON-RPC interface. Free public Soroban RPC endpoints are available without an API key from Gateway.fm, Ankr, OnFinality, SorobanRPC.com and Lightsail Network. Every provider was live-verified with consecutive keyless getLatestLedger probes at launch.
Methodology
Stellar Soroban: 5 free public RPC endpoints answering `getLatestLedger` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. Gateway.fm leads at 142 ms. We measure the round-trip latency of a single, identical JSON-RPC call (getLatestLedger) against every no-key public Stellar Soroban endpoint that sustains continuous probing: 5 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 Stellar-scaled staleness gap (roughly 5 s per ledger). The cross-chain view lives on the parent rpc-capabilities benchmark; this page is the Stellar-scoped answer with per-region breakdowns as a first-class dimension.

Frequently asked
Which Stellar Soroban RPCs work without an API key?
5 endpoints are probed on this chain; each is listed with its URL, 24h median and success rate in the endpoints table on this page, and the list changes as providers come and go. Every listed endpoint was live-verified with a `getLatestLedger` request before inclusion.
What is the difference between Stellar Horizon and Soroban RPC?
Horizon is Stellar's REST API for classic payments and account operations. Soroban RPC is the JSON-RPC interface for Stellar's smart contract platform. This benchmark measures Soroban RPC endpoints since they are the primary interface for dApp developers building on Stellar.
