WARNING. The best Starknet RPC provider can depend on your location because they use different data centers.
The RUN button below tests endpoints from the location of your browser with a POST / GET request. It works like Postman for web3 but without a proxy and with linear interpolation for p95. Errors about 429 indicate low rate limits.
Additional providers with free, private and paid accounts are in our directory for Starknet infrastructure providers
