Fastest free Juno RPC, live no-key endpoint latency
HTTP round-trip latency for the Tendermint status method against every free, no-key public Juno Cosmos SDK endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Polkachu leads rpc latency at 193 ms (p50, 24h) on Fastest free Juno RPC, live no-key endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/juno-rpc.

Juno (juno-1) is a Cosmos SDK blockchain and the original CosmWasm smart contract hub in the Cosmos ecosystem, JUNO staking token, using CometBFT consensus. It hosts an active ecosystem of DEXes, lending protocols, and NFT platforms built with CosmWasm. Polkachu, PublicNode, and LavenderFive provide keyless Tendermint RPC endpoints probed every 60 seconds from three regions.
Methodology
Per-chain member of the RPC latency cluster, extended to Juno. We measure the round-trip latency of a single, identical Cosmos SDK call (Tendermint `status`) against every no-key public Juno endpoint that sustains continuous probing, 4 providers at launch, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) so the leaderboard rewards sustained availability rather than fast error messages. The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Juno-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Juno RPC right now?
Polkachu currently leads at 193 ms (Tendermint `status` 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.
Which Juno RPCs work without an API key?
4 endpoints sustain continuous keyless probing at launch: Polkachu, PublicNode, LavenderFive, AutoStake. Every listed endpoint was live-verified before inclusion.
Does the fastest Juno RPC change by region?
Often. 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 Juno RPC latency measured here?
One identical Tendermint `status` POST every 60 seconds against each provider from each of 3 regions. Responses are classified so an endpoint stuck on an old block is never ranked as fastest.
