Blockcypher offers a free blockchain explorer that supports multiple networks including BTC, ETH, LTC and several other networks. They are the only blockchain explorer that provides accurate transaction fee estimates in real-time that can be referenced to ensure that your transaction includes a sufficient value to be confirmed in the immediate block that follows the transaction broadcast. With higher TPS capable networks like Solana, this isn't very relevant because the confirmations are lightning fast but with legacy networks like BTC, the confirmations can't sometimes take 30-60 minutes. Being delayed for even a single block eats up valuable time and can be frustrating as such. Blockcyphers advanced infrastructure affords them the advantage of having one of the fastest network explorers in existence. A great resource and infrastructure for web3 companies and/or decentralized apps.
