CompareNodes team have released a light-weight HTTP client optimized for Web3.
We named it MilliNet because it measures round-trip milliseconds from the browser to any mainnet, testnet or devnet as min, max, avg, p50 and p95.
MilliNet works like Postman for POST RPC and GET RESTful requests:
- It is light-weight and runs entirely in the browser, without a backend proxy
- MilliNet measures p50 and p95 round-trip times between the browser and public or private endpoints
- The p95 calculation already utilizes linear interpolation and improvements are in our roadmap
- Users can dispatch single requests or run in loops up to 100, with or without throttling
Standalone and iFrame
- MilliNet can be embedded in an iFrame into any website as a free RPC sandbox / playground
- The standalone UI is available at CompareNodes.com/millinet/
- iFrame configuration params are in this list
- See the black-and-white iFrame below
The iFrame UX is best with width of >=360px and the default configuration without parameters can be achieved with this HTML:

Optional Configuration
e.g. comparenodes.com/millinet/millinet-widget/?protocolGroup=eth_chainId&endpointURL=https://mainnet.base.org/
| Parameter | Description | URL with Example |
| endpointURL | Fill in the initial value for the Endpoint URL. | &endpointURL=https://mainnet.base.org/ |
| endpointSLD | Set a restriction to second-level-domain: the form will reject values in the Endpoint URL input for domains except those that match the parameter. The example restricts the form to URLs with “onfinality.io” only. | &endpointSLD=onfinality.io |
| showAuthControls | Set it to false to hide the Auth Header pull-down (and its header value input). This option can be useful for sites which offer only public endpoints to make the MilliNet widget/form more compact. | &showAuthControls=false |
| filterAuthHeader | For providers which offer public endpoints and private endpoints with authentication via the header: set this parameter to the specific header and the pulldown will show NO + the parameter. Available values are: x-api-key, apikey, api-key, Authorization, project_id, dmtr-api-key and Drpc-Key. Do not use this parameter with &showAuthControls=false | &filterAuthHeader=apikey |
| selectAuthHeader | For providers which do NOT offer public endpoints and their private endpoints are authorized with an auth header: set this parameter to the auth header that you use and it will be the only selection in the pulldown. Available values are: x-api-key, apikey, api-key, Authorization, project_id, dmtr-api-key and Drpc-Key. Do not use this parameter with &showAuthControls=false | &selectAuthHeader=x-api-key |
| defaultLoop | Use it to replace the MilliNet’s value of 10 with a new default/initial for the loop. Must be >=2. The user can also change it to another value, up to 100 (see parameter maxLoop). | &defaultLoop=5 |
| maxLoop | This parameter should be used to restrict the max value that the user can set for a loop request. Must be >=3 and > defaultLoop, if any. When this value is set to =3, the form will display just the RUN-x1 and START-x3 buttons for a more compact layout. | &maxLoop=25 |
| protocolGroup | Exists to access RPC / RESTful examples for requests to most popular protocols: EVM, UTXO, Substrate, Tendermint, Aptos, Sui, Algorand, NEAR etc. See the next table below with the complete specification. | &protocolGroup=eth_getBlockByNumber |
