# Metadata Explorer

The `Metadata Explorer` tool helps visualize the metadata of various parachains by retrieving the latest data directly from the chain using the [polkadot-js api](/reference/tools/polkadot-js-api/). The dropdown below allows you to update the chain selection to visualize. You can search all sub-categories using the provided search field. The information is categorized by the chains Pallets, RPC and Runtime information.

:::note[Info]
You can enter custom RPC endpoints for Polkadot SDK based chains and explore their metadata using [Parity Tech Subxt Explorer](https://paritytech.github.io/subxt-explorer/#/).
