$49 Global RPC Performance Showdown: Dwellir vs. Chainstack

About the Showdown

Dwellir and Chainstack are amongst the leading infrastructure providers in web3. Both serve many protocols with support for JSON-RPC and WebSocket interfaces. Their entry level paid price-point is $49/mo which deliver comparable requests-per-second and cost per request.

We purchased our own paid accounts with Dwelllir and Chainstack for $49/mo to compare their global RPC performance using our own global RPC Inspector Pro (see its documentation).

This analysis is not sponsored. For additional information please contact Simon on LinkedIn.

All Runs

  • From 31 global locations on 6 continents; all probes in AWS;
  • HTTPS runs with throttling 1.1 sec start-to-start; 15 iterations; two requests per;
  • WSS runs subscribe newHeads;
  • Using our own RPC Inspector Pro.

Implementation

  • 5 consecutive days: May 6 – May10 2026;
  • 3 rounds per day for HTTPS;
  • 3 rounds per day for WSS;
  • Each round is Dwellir endpoint vs. Chainstack endpoint;
  • All endpoints from the same account for the respective provider;
  • Each round runs alone to minimize account requests-per-second.

Disclaimer

  • Using a different subset of locations can result in different overall results / conclusion: e.g. you might not care about an entire continent group; use RPC Inspector Pro to conduct new analysis to match the locations (regions) best suited for your consumption patterns.

Methods

  • EVM
    • HTTPS JSON-RPC: eth_getBlockByNumber(latest, false) & eth_getLogs(hash from eth_getBlockByNumber);
      • winner for each method is the lower-is-better p95 latency in milliseconds for the global rollup from 31 locations;
    • WSS eth_subscribe(newHeads);
      • winner for each block-location (region) is the earlier arrival in that location;
      • winner of the run is the higher total number of winners across all block-location combinations;
      • In some cases, the providers can be “Tied” on block-location arrival.

Overall Results

Ethereum Mainnet

  • Chainstack wins 43 of 45 possible major performance metrics across the combined 30 runs for HTTPS and WSS;
  • Chainstack scores the perfect 100% for blockNumber consistency and blockAvailability while Dwellir had issues in both areas during multiple runs, albeit >90%;
  • Chainstack recorded a few timeouts at 4,000 millis (enforced by our probes).

Btw, we used a screenshot below because WordPress tables are PITA. You can access details for individual runs in the Date columns of this public google sheet.
