Hi Product Hunt — I built FlowLens to shorten the most frustrating part of operating n8n workflows: moving between execution history, copied JSON, credentials, and ad-hoc webhook tools just to understand and reproduce a failure. The integration is intentionally simple. Import one of the supplied templates or add an HTTP Request node, then FlowLens gives you a sanitized execution inbox, structured comparison, saved test payloads, and deliberate replay to an approved destination. It does not replace n8n; it gives developers and agencies a focused debugging workspace around it. There is a useful free plan, and the complete live demo needs no account. I would especially value feedback from people who operate client workflows: which part of failure investigation still costs you the most time?
