I really needed a visual tool which I could use to search for assets on a certain BigchainDB network on the fly. I didn't really found one so I decided to create one. Enjoy!
You just load the page and start typing a string you want to query! Click on an asset to get a list of transactions and click on a transaction to get a detailed overview of its data.
By default, the snooper will point to the official BigchainDB Testnet, but you can point it to any node by changing the URL in the settings pane.
