Blockscout is widely used by the community with a current average of 500K monthly pageviews for instances we host. This number is much larger for all instances, but we do not have access to any metrics for self-hosted instances. Our primary repo has 2.4K forks and 3.6K stars. Blockscout is used as an explorer on over 1000 chains, and the primary option for most RaaS providers deploying rollups using the Optimism or Arbitrum stacks.  We have many testimonials on our website at blockscout.com from industry veterans who use and recommend Blockscout.
