# 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.md). 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.

    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/#/).
