About

Tenderly simulates transactions before sending, debugs contracts line by line and replays historical events, with monitoring and alerts — the tool for untangling complex transactions.

Far more efficient for failed-transaction debugging than reading raw logs; team collaboration is strong. Usage-based pricing adds up for heavy users.
