How Scanner compares with Arkham, Bubblemaps and Solscan for Solana and Robinhood Chain investigations, and where each tool is the better pick.
Arkham is the broader tool: entity attribution across many chains, plus alerts. Scanner is narrower and deeper on Solana and Robinhood Chain: a free explorer that shows where any wallet's funds came from, bundle detection on token holders, bubble maps, and Seek for following Solana funding trails hop by hop. If you investigate memecoin launches, bundles and Solana funding trails, Scanner is the more direct fit; if you need attribution across Bitcoin, Ethereum and dozens of other chains, use Arkham.
Bubblemaps made the token bubble map famous and covers about fifteen chains for free, including Magic Nodes, which reveal intermediaries such as a shared gas funder that aren't holders themselves. Scanner's bubble map comes out of a full scan on Solana or Robinhood Chain: each cluster arrives with a funding trace walked back toward its original source, labeled bundle and insider groups, and exchange labels, plus KOL labels and a path into Seek on Solana. Use Bubblemaps for a quick free look, especially on a chain Scanner doesn't cover; use Scanner when you need the funding trail behind a cluster and whether it is a bundle.
Solscan is a leading Solana block explorer and the right pick for raw lookups and developer data. Scanner is a free Solana explorer too, but every wallet shows where its funds came from, and one click runs a scan for connected wallets, bundles and a bubble map. Scanner also covers Robinhood Chain.
